The Authority of the Divine King
(Mark 1:21–28)

They went into Capernaum; and immediately on the Sabbath He entered the synagogue and began to teach. They were amazed at His teaching; for He was teaching them as one having authority, and not as the scribes. Just then there was a man in their synagogue with an unclean spirit; and he cried out, saying, “What business do we have with each other, Jesus of Nazareth? Have You come to destroy us? I know who You are—the Holy One of God!” And Jesus rebuked him, saying, “Be quiet, and come out of him!” Throwing him into convulsions, the unclean spirit cried out with a loud voice and came out of him. They were all amazed, so that they debated among themselves, saying, “What is this? A new teaching with authority! He commands even the unclean spirits, and they obey Him.” Immediately the news about Him spread everywhere into all the surrounding district of Galilee. (1:21–28)

Life’s most critical question is, “Who is Jesus Christ?” How a person answers that question has eternal implications. Nothing is more essential, either for this life or the life to come, than knowing the truth about Jesus. Yet few seem seriously interested in rightly understanding who He is and why He came. Tragically, many people blindly assume that Jesus was merely a good teacher, a moral idealist, or a misunderstood social activist whose life ended in tragedy two millennia ago. That is not how Scripture presents Him, nor is it in keeping with who He declared Himself to be.

The gospel of Mark (like the other three) provides a definitive answer to that question in the very first verse. Mark 1:1 declares Jesus to be the Christ—the messianic King—and the Son of God. He is the divinely appointed ruler to whom all the prerogatives of royalty are due. Moreover, He is God incarnate, worthy of all glory, honor, and praise. He is the Lord of lords, possessing all authority both in heaven and on earth (cf. Matt. 28:18). Consequently, the only right response to His sovereign dominion is to submit and worship Him as the eternal King of kings and the glorious Son of God. Any depiction of Jesus that undermines or belittles His true person and position is not only inadequate, it is blasphemous. Though many demean and disparage Him now, all will one day recognize Him for who He truly is. As the apostle Paul told the Philippians, “At the name of Jesus every knee will bow, of those who are in heaven and on earth and under the earth, and that every tongue will confess that Jesus Christ is Lord, to the glory of God the Father” (Phil. 2:10–11).

Mark 1:21–28 is a passage that dramatically illustrates both the sovereign authority of Jesus Christ and the stubborn unwillingness of unbelieving sinners to recognize and submit to that authority. The passage comes on the heels of Mark’s introduction (in vv. 1–20), in which he presented five proofs to demonstrate that Jesus is indeed the divine King: Jesus was preceded by a royal forerunner (1:2–8), experienced a divine coronation ceremony (1:9–11), defeated His archenemy the prince of darkness (1:12–13), proclaimed the kingdom message of salvation (1:14–15), and commanded His kingdom citizens to follow Him (1:16–20). Heralded by John, commissioned by the Father, filled with the Spirit, victorious over sin and Satan, and accompanied by His disciples, the Lord Jesus began His public ministry with every necessary credential demonstrated. So, succinctly but convincingly, Mark’s fast-moving, condensed, and selective introduction established the messianic character and divine nature of the Lord Jesus. From this point forward, as Mark begins the body of his gospel record, he will slow his pace to focus more intently on specific events from the ministry of the messianic King.

The history begins in verse 21 with the inspired recounting of an incident in which Jesus demonstrated His authority over the demonic realm. Mark has already highlighted Christ’s authority over Satan, sin, and sinners in verses 12–20. In this section (vv. 21–28) he continues that theme, specifically focusing on a dramatic showdown one Sabbath day between Jesus and a demon. Once again, the cosmic authority of Jesus is vividly put on display, leaving no doubt about the King’s ability to dominate demons and to obliterate the satanic bondage that can hold sinners captive all the way to hell.

The passage itself reveals a striking contrast between the response of people to Jesus’ authority and the response of demons. On the one hand, people were amazed at Jesus’ power and authority (vv. 22, 27). They reacted with wonder, curiosity, and surprise because He taught as no one they had ever heard before. On the other hand, demons were terrified by Christ. They responded in horror, dread, and panic. Those divergent reactions lie at the heart of understanding the significance of this passage. Both the demons and the people were sinful. Yet, only the demons shrieked in fear. They understood Jesus was their Judge who would cast them into hell. The people certainly did not.

Ironically, in the first half of Mark’s gospel, the only beings sure of Jesus’ true identity were the demons. The Jewish leaders rejected Him (3:6, 22); the crowds were curious but largely uncommitted (6:5–6; cf. John 2:24); and even His disciples exhibited a lingering hard-heartedness (8:17). But the demons knew for certain. As Mark explains, “Whenever the unclean spirits saw Him, they would fall down before Him and shout, ‘You are the Son of God!’” (3:11). Knowing exactly who Jesus was and what He had the power to do, they responded with terror—fearing He might cast them immediately into the abyss (Luke 8:31; cf. Rev. 9:1). As one unclean spirit cried out, “What business do we have with each other, Jesus, Son of the Most High God? I implore You by God, do not torment me!” (5:7). They had known the Son of God since He created them (Col. 1:16). Their ancient minds were full of the particulars about their heavenly rebellion, defeat, and expulsion; they understood the eternal punishment that yet awaits them in the lake of fire (Matt. 25:41). Understandably, the demons were utterly terrified in Jesus’ presence. Now that the Son had come to earth to begin the establishment of His rule, the evil angels had every reason to be tormented by terror.

There is no salvation for fallen angels (Heb. 2:16). However, sinners who come to a true understanding of the authority of the Son of God, and are terrified by the threat of hell are invited to flee from wrath and run in holy fear to Christ for the forgiveness and grace of salvation. Yet the vast majority of sinners who hear the good news of heaven still refuse to fear hell and come to Christ for the gift of salvation. Such is the great irony depicted by this passage. The demons recognized who Jesus was, but have no possibility of salvation. The crowds were offered divine forgiveness, but they refused to recognize the One who alone can provide it. Put another way, the demons were terrified and could not be saved; the people were amazed and would not be saved. Consequently, the amazed people (who would not believe) and the terrified demons (who do “believe, and tremble”—James 2:19 KJV) will ultimately end up in the same eternal lake of fire (Rev. 20:10–15).

It is important to emphasize that during Jesus’ ministry, the demons did not attack Him. They assaulted the souls of sinful people but never Jesus. In fact, whenever a confrontation occurred, it was Jesus who attacked them. His mere presence sent them into a frenzied panic. Though invisible to the naked eye, they were not invisible to Him. They might be able to hide from people—disguising themselves as angels of light (2 Cor. 11:14) and dwelling comfortably within the confines of apostate religion. But they could not hide from the omniscient gaze of Christ. In His presence, they blew their cover due to the constraining power of their fear.

Throughout His entire ministry, Jesus’ dominance over the demons was absolute and uncontested—indicative of the fact that He possessed absolute power over the devil and the entire force of fallen angels in the “domain of darkness” (Col. 1:13). He is able to overwhelm Satan—the one who controls this world system (1 John 5:19), and who has blinded sinners (2 Cor. 4:3–4) and holds them captive (Heb. 2:14–15)—in order to set sinners free (John 8:36). As the apostle John explained, “The Son of God appeared for this purpose, to destroy the works of the devil” (1 John 3:8). The new King needed to demonstrate His power to dethrone Satan and rescue sinners from his grip. To be sure, the demons knew why the Son of God had come. They knew the King of salvation had arrived, and the prince of darkness needed his spiritual forces to do everything in their capacity to oppose Him. From the start of the Lord’s ministry, it was apparent that they were no match for His unsurpassed sovereign authority. It was divine power that threw them out of heaven and would one day throw them into hell. In between those two events, during Jesus’ earthly ministry, the Lord’s invincibility over the satanic realm was vividly put on display in every encounter with a demon.

This passage (1:21–28) relates one of what must have been many such encounters. Here Jesus confronted a traumatized and exposed demon while teaching in the synagogue in Capernaum. In 1:23, Mark explains that the demon cried out to Jesus. The verb translated “cried out” (anakrazō) means to scream or shout with strong emotion and describes the shrieks of someone experiencing intense agony. The demon’s screeching outcry was abrupt, disruptive, and startling. Mark relates the dark angel’s panic to three aspects of Jesus’ authority: the authority of His word, the authority of His judgment, and the authority of His power.

THE AUTHORITY OF HIS WORD

They went into Capernaum; and immediately on the Sabbath He entered the synagogue and began to teach. They were amazed at His teaching; for He was teaching them as one having authority, and not as the scribes. (1:21–22)

Although the demon’s reaction is not recorded until verse 23, these two verses describe the initial reason for his outburst. His violent outcry came in immediate response to the authoritative teaching of Jesus. The words of Christ ignited flames of dread in his consciousness, which erupted loudly as exclamations of terror and anguish.

Mark introduced this episode by noting that they (meaning Jesus and His recently called disciples) went into Capernaum. The name Capernaum means “village of Nahum.” It was likely a reference to the hometown of the Old Testament prophet Nahum. But Nahum also means “compassion,” perhaps indicating that the town was also named for its compassionate residents. Located on the northwest edge of the Sea of Galilee, Capernaum was a prosperous fishing town. It was here that Peter, Andrew, James, and John had their fishing operation, and where Matthew worked as a tax collector (Matt. 9:9). Built on a major Roman road, the Via Maris, Capernaum was an important commercial town. According to historians, it had a promenade that stretched nearly half-mile long and sat on top of an eight-foot seawall. From there, piers jutted approximately one hundred feet out into the water, giving fishing boats easy access to the city. It contained a Roman garrison and was located in the tetrarchy of Herod Antipas, on the border of his brother Philip’s domain. After being rejected at Nazareth (Matt. 4:13; Luke 4:16–31), Jesus established His headquarters there during His Galilean ministry (cf. Mark 2:1).

Mark continued by explaining that immediately on the Sabbath He entered the synagogue and began to teach. That was not unusual, since it had always been Jesus’ habit to attend the synagogue every Sabbath (cf. Luke 4:16). The Jewish system of synagogues had initially developed in the sixth century B.C. during the Babylonian exile. Prior to the exile, worship centered in one place, the temple in Jerusalem. When Solomon’s temple was destroyed, and the Jews were in captivity for seventy years, the people began to meet together in small group gatherings. Even after the Jews returned to their homeland and rebuilt the temple, they continued to structure the community life of local villages and towns around what had become official synagogues (the Greek word translated synagogue means “gathering” or “assembly”). As a result, the synagogue became the center of Jewish community life—a place of local worship, a meeting hall, a school, and a courtroom. Traditionally, a synagogue could be formed in any place where there were at least ten Jewish men. Consequently, larger cities in the ancient world often contained numerous synagogues.

One of the primary functions fulfilled by the synagogue was the public reading and exposition of Scripture, a practice that went back at least to the time of Nehemiah. A policy known as “freedom of the synagogue” allowed any qualified man in the congregation to deliver the exposition of the Old Testament passage. That privilege was often extended to visiting rabbis, as it was on this occasion to Jesus. The apostle Paul similarly used such opportunities to proclaim the gospel in various cities throughout the Roman Empire (cf. Acts 9:20; 13:5; 18:4; 19:8). Because the news about Jesus’ miracles had already spread (cf. Luke 4:14), the attendees in Capernaum would have been eager to hear Him teach.

Mark does not detail the content of the message Jesus preached to the congregation that Saturday in Capernaum. Instead, he focused on the people’s response. They were amazed at His teaching; for He was teaching them as one having authority, and not as the scribes. The people were shocked. Never before had they heard a rabbi speak with such power, precision, and gravitas.

The word authority (exousia) speaks of rule, dominion, jurisdiction, full right, power, privilege, and prerogative. Jesus taught with absolute conviction, objectivity, dominion, and clarity. He spoke the truth with the unwavering confidence of the divine King, and the people could only respond in wonder (cf. Matt. 7:28–29). What a contrast Jesus’ profoundly piercing words were to the esoteric pontifications of the scribes, who loved to quote the multitudinous views of other rabbis. They often taught in ways that were mystical, muddled, and often focused on minutiae. But Jesus was clearly different. He did not derive His theology from the musings of other people, nor did He offer a variety of possible explanations. His teaching was absolute not arbitrary. It was logical and concrete, not evasive or esoteric. His arguments were reasonable, inescapable, and focused on essential matters.

Scribes were the primary teachers in first-century Jewish society. They traced their heritage back to Ezra who, according to Ezra 7:10 and Nehemiah 8:4–8, read the law and explained it to the people. Most people had only limited access to the Scriptures, copies of which were too expensive for ordinary, working-class people to own. Consequently, they would go to the synagogue to hear the Scriptures read and explained by the scribes. Because they handled the Scriptures, the scribes became so revered that they were given the title “rabbi,” meaning “honored one.” Over the centuries, from the time of Ezra to the time of Christ, the teaching of the scribes grew less focused on the text of Scripture and more focused on what previous rabbis had said. By the first century, scribes prided themselves on being familiar with all possible views. Rather than faithfully explaining the simple meaning of Scripture, they delighted in complex musings, fanciful allegories, obscure insights, mystical notions, and the teachings of earlier rabbis.

When Jesus began to explain the biblical text perfectly with clarity, conviction, and authority, His listeners were stunned. They had never heard anything like it. Their astonishment is bound up in the word amazed (ekplessō), which literally means “to be struck out of one’s self” with awe and wonder. To use the vernacular, Jesus blew them out of their minds. There are a number of New Testament words that can be translated “amazed” or “astonished.” This is one of the strongest and most intense. Jesus’ message was so riveting and powerful that His audience sat in stunned silence, hanging on to every word He uttered (cf. Luke 19:48).

The silent awe would be violently interrupted by the screams coming through the lips of a demon-possessed man. It was the demon who was panicked by the truth of Jesus’ preaching and could not remain hidden in the man any longer. Mark introduces the demon in verse 23, noting the immediacy of the evil spirit’s reaction to Jesus’ preaching. Unable to restrain himself, the demon erupted in a fit of shrieking rage in response to the truth the Son of God proclaimed.

It is not surprising to find this evil spirit hanging around the synagogue. The demons had developed a false system of hypocritical religion that was highly successful in first-century Israel. As is their nature, demons hide in the middle of false religion, disguising themselves as angels of light (2 Cor. 11:14) and perpetuating error and deceit (cf. 1 Tim. 4:1). Like their leader Satan, they are liars and murderers who seek people’s eternal destruction. In John 8:44–45, Jesus told the Pharisees, “You are of your father the devil, and you want to do the desires of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. Whenever he speaks a lie, he speaks from his own nature, for he is a liar and the father of lies. But because I speak the truth, you do not believe Me.” Those verses summarize the heart of the conflict. Satan and his hosts propagate lies for the purpose of perpetuating spiritual death. But Jesus is the way, the truth, and the life (John 14:6). When Jesus preached the truth on that Sabbath day, the demon who heard Him teach was involuntarily exposed. Confronted by the authority of Jesus’ words, the fallen angel reacted with a terrified scream.

THE AUTHORITY OF HIS JUDGMENT

Just then there was a man in their synagogue with an unclean spirit; and he cried out, saying, “What business do we have with each other, Jesus of Nazareth? Have You come to destroy us? I know who You are—the Holy One of God!” (1:23–24)

Mark’s use of the phrase just then (euthus) underscores the immediacy of the demon’s reaction. It followed directly on the heels of Jesus’ preaching. His shrieking outburst provided audible evidence that fallen angels tremble at the power of Christ’s word. The content of his exclamation, which is recorded in verses 23–24, indicated that the demon was also terrified by the authority of Christ’s judgment.

Demon possession—always present, usually hidden—was dramatically and uniquely exposed during the ministry of Jesus Christ. The rebellious angels were unable to remain concealed in His presence. In the Old Testament, outside of Genesis 6:1–2, there are no recorded instances of demon possession. In the book of Acts, there are only two (Acts 16:16–18; 19:13–16). The Gospels, however, abound with it (Matt. 4:24; 8:28; 9:33; 10:8; 12:22–27; Mark 1:23–27; 5:4–13; 9:25; Luke 4:41; 8:2, 28; 9:39; 13:11). Confronted by the glory of the Son of God Himself, the demons revealed their identities, often in violent and remarkable ways.

On this occasion, the demon-possessed man responded by screaming at the top of his lungs—the demon inside him borrowing the man’s vocal chords to express pure terror. In a burst of dread mixed with rage, the demon asked, “What business do we have with each other, Jesus of Nazareth? Have You come to destroy us? I know who You are—the Holy One of God!” The use of plural pronouns (we and us) suggest that this particular demon was asking these questions on behalf of fallen angels everywhere. As those who had joined in Satan’s failed coup (cf. Isa. 14:12–17; Ezek. 28:12–19), demons once served in the presence of God. They knew each member of the Trinity intimately and immediately recognized Jesus as God the Son whenever they found themselves in His presence. They knew He was the Holy One of God, the messianic King who had come to save the world from the power of Satan (Luke 4:41).

In speaking to Christ, this demonic spirit employed two different names—one of which expressed his antagonism, the other his fear. The first, Jesus of Nazareth, carried a tone of scornful disdain. Nazareth was an obscure town, held in low esteem by other Israelites (cf. John 1:46). The Jewish leaders, in particular, used the term as a pejorative, because they mocked the idea that the Messiah would come from such humble, Galilean origins (cf. John 7:41, 52). In referring to Jesus’ hometown, the demon joined the scorn of the disbelieving crowds.

At the same time, the evil spirit knew exactly who Jesus was. Consequently, his scorn is mixed with terrified dread. As a wretched fallen angel, his response was one of enmity intermingled with fear. He called Jesus the Holy One of God because he was fully aware of Jesus’ divine authority. This unclean spirit, a being characterized by ultimate depravity and incurable wickedness, cringed in the presence of perfect virtue and holiness.

The demons knew that “the Son of God appeared for this purpose, to destroy the works of the devil” (1 John 3:8). Fully aware they were irredeemable, and would one day be cast in the lake of fire (Matt. 25:41), they feared the hour of their final destruction had come. Later in Jesus’ ministry, other demons asked almost the same question: “What business do we have with each other, Son of God? Have You come here to torment us before the time?” (Matt. 8:29). The demons recognized exactly who Jesus was. They knew He had full authority and power to cast them into eternal punishment on God’s appointed judgment day. That is why they repeatedly responded with such panic and dismay (cf. James 2:19).

The impending reality of future judgment explains the demon’s response to Jesus on that Sabbath day in Capernaum. As an operative of Satan, he would have undoubtedly preferred to remain undetected—hidden in the shadows of hypocritical religion. Instead, overwhelmed with dread and panic, he could only uncover himself in a dramatic outburst.

THE AUTHORITY OF HIS POWER

And Jesus rebuked him, saying, “Be quiet, and come out of him!” Throwing him into convulsions, the unclean spirit cried out with a loud voice and came out of him. They were all amazed, so that they debated among themselves, saying, “What is this? A new teaching with authority! He commands even the unclean spirits, and they obey Him.” Immediately the news about Him spread everywhere into all the surrounding district of Galilee. (1:25–28)

Though the eschatological day of eternal judgment for Satan and his angels has not yet come (cf. Rev. 20:10), this demon was given a foretaste of Christ’s absolute authority over him. He was cast out by the same power that will one day cast him into the lake of fire.

Unfazed by the demon’s histrionics, Jesus rebuked him. As the divine King, He possessed the inherent authority to command this fallen angel. No dialogue, negotiation, or struggle was necessary. Attempted exorcisms involving various formulas and rituals were not uncommon among the Jews of New Testament times, though they produced no real success. But Jesus’ success rate was perfect. He never failed to cast out the demons He confronted, nor did He rely on any special formulas or rituals to do so. He simply issued a command and the demons obeyed.

The Lord delegated that power to His apostles and they did the same (Luke 9:1). Apart from Jesus and the apostles, the New Testament never presents exorcism as a practice in which believers ought to engage. In fact, when non-apostles tried to usurp that kind of authority, the results were disastrous. The seven sons of Sceva learned that lesson painfully. When they tried to cast an evil spirit out of a man by the power of “Jesus whom Paul preaches, … the evil spirit answered and said to them, ‘I recognize Jesus, and I know about Paul, but who are you?’ And the man, in whom was the evil spirit, leaped on them and subdued all of them and overpowered them, so that they fled out of that house naked and wounded” (Acts 19:13–16). Rather than engaging in exorcisms, believers today are called to engage in evangelism. Whenever we bring the gospel to nonbelievers and they put their faith in the Lord Jesus Christ, the Holy Spirit washes them clean, takes up residence, and the demons are evicted.

Jesus’ rebuke came in the form of two short imperatives: “Be quiet, and come out of him!” The demon had no choice but to obey immediately. The first command silenced the demon; the second drove him out. Throughout Jesus’ ministry, He repeatedly forbade the unclean spirits to testify about Him (cf. Mark 1:34). Though their identification of Jesus was accurate, He did not need any publicity from the agents of Satan. As it was, the religious leaders accused Him of casting “out demons only by Beelzebul the ruler of the demons” (Matt. 12:24). Permitting the demons to continue speaking about Him would only have added support to the sneering speculations of the Pharisees. So whenever they affirmed His identity, He shut them up (cf. Acts 16:16–19).

Jesus’ second command, come out of him, resulted in the demon’s violent departure. The unclean spirit preferred to remain to hold that man’s soul captive for hell. But he was forced to go, unwillingly but not quietly. As Mark records, Throwing him into convulsions, the unclean spirit cried out with a loud voice and came out of him. With one dramatic final protest, causing the man’s body to convulse, the demon let out a final scream as he departed.

The scene is reminiscent of another demon Jesus encountered, later in His ministry, the day after His transfiguration. Mark relates that story in Mark 9:25–27:

Like the demon described in Mark 1:23, this demon showed his rebellious objection to Christ with a final, violent thrashing of his victim. But it was only a momentary frenzy. Like every other fallen angel, he was no match for the sovereign power of the divine King, and once he left, the boy whom he had tormented was healed. Though the demon-possessed man in the synagogue in Capernaum was similarly thrown into convulsions, the demon did no damage. As Luke explains in the parallel account: “When the demon had thrown him down in the midst of the people, he came out of him without doing him any harm” (Luke 4:35).

Neither Mark nor Luke provide any biographical information about the man who was delivered. But the lack of detail is intentional, because the focus is not on him. It is on the One who liberated him from demonic possession. Appropriately, the attention centers on the Son of God, who again publicly displayed His divine power. By His own authority He commanded the demon to flee. Only the divine King has the power necessary to break the bondage of Satan. He can destroy the devil, dismantle his forces, and deliver captive souls.

Jesus’ power was unmistakable, so that those who sat in the synagogue, who had already been amazed by His teaching, were all amazed at His ability to deliver this demon-possessed man. They had no category for what they had just witnessed, so that they debated among themselves, saying, “What is this? A new teaching with authority! He commands even the unclean spirits, and they obey Him.” The crowd began to buzz with excitement over what had transpired. They had been stunned by the authority of His teaching and then equally shocked by the power He exercised over the unclean spirits. The debate was not a formal one but rather the excited chatter of wonder expressed by those who were amazed. Eventually, however, that debate would grow more polarizing. While no one could deny His authority over demons, the religious leaders would begin to question the source of that authority (cf. Matt. 12:24).

In the meantime, word about Jesus began to get out. As Mark explains, “Immediately the news about Him spread everywhere into all the surrounding district of Galilee.” This was just the beginning. Mark 1:39 reports that “He went into their synagogues throughout all Galilee preaching and casting out the demons.” The divine King launched His public ministry by putting on displays of power over evil spirits unprecedented in Israel and the world (cf. Matt. 9:33). He taught like no one else and He possessed and used force that no one else had ever seen. Behind His power was Jesus’ authority. The demons recognized Him and were terrified; the crowds witnessed Him and were amazed. The demons believed Him but could not be saved; the crowds refused to believe in Him and, therefore, would not be saved.

A combination of both responses is necessary for salvation. Sinners need to be both terrified and amazed: terrified by such a Judge and astonished by such a Savior. It is not enough simply to be amazed by Jesus Christ. He is not satisfied with mere curiosity, wonder, or astonishment. He wants sinners to fear Him as the Judge and then run to Him as the Savior.

The people who heard Jesus teach and witnessed His authority on that Sabbath day in Capernaum were left with no excuses. Yet, the population of that city ultimately rejected Him as their Lord and Savior (Matt. 11:23; Luke 10:15). Perhaps they considered Jesus a good teacher, a moral idealist, or a misunderstood social activist. None of those conclusions was adequate. They may have been amazed by Him in the moment, but unless they came to embrace Him in saving faith—worshiping Him as the Son of God, trusting in Him as the Savior of the world, and submitting to Him as the Lord over all—their amazement was ultimately worthless. It was no better than the trembling terror of the demons. So it is for all who reject the true person and work of Jesus Christ.
