The title "Son of Man" is one of the most significant and frequently used titles for Jesus Christ in the New Testament, emphasizing both His humanity and His divine authority. This title, deeply rooted in the Old Testament, particularly in the book of Daniel, is pivotal in understanding the scope and nature of Jesus' mission and authority.

Old Testament Background

The term "Son of Man" appears prominently in Daniel 7:13-14, where the prophet Daniel describes a vision: "In my vision in the night I continued to watch, and I saw One like the Son of Man coming with the clouds of heaven. He approached the Ancient of Days and was led into His presence. And He was given dominion, glory, and kingship, that the people of every nation and language should serve Him. His dominion is an everlasting dominion that will not pass away, and His kingdom is one that will never be destroyed." . This passage highlights the eschatological figure who is granted authority, glory, and sovereign power by God, the Ancient of Days.

New Testament Fulfillment

In the New Testament, Jesus frequently refers to Himself as the "Son of Man," a title that encapsulates His role as the Messiah and His divine authority. This self-designation is used in various contexts to assert His authority over creation, His role in redemption, and His future judgment.

1. Authority to Forgive Sins: In Mark 2:10, Jesus declares, "But so that you may know that the Son of Man has authority on earth to forgive sins..." . This statement, made in the context of healing a paralytic, underscores His divine prerogative to forgive sins, a power traditionally ascribed to God alone.

2. Lord of the Sabbath: In Mark 2:28, Jesus asserts, "So the Son of Man is Lord even of the Sabbath." . This claim highlights His authority over Jewish law and tradition, affirming His divine lordship and reinterpretation of the Sabbath.

3. Authority in Teaching: The Gospels frequently depict Jesus teaching with authority, as seen in Matthew 7:29, "because He taught as one who had authority, and not as their scribes." . His teachings, often prefaced with "Truly, I say to you," reflect His unique authority to reveal divine truth.

4. Authority over Nature and Demons: Jesus demonstrates His authority over nature and spiritual forces, calming storms (Mark 4:39) and casting out demons (Mark 1:27). These acts reveal His sovereign control over creation and the spiritual realm.

5. Authority in Judgment: Jesus speaks of His future role in judgment, as seen in Matthew 25:31-32, "When the Son of Man comes in His glory, and all the angels with Him, He will sit on His glorious throne. All the nations will be gathered before Him..." . This eschatological authority underscores His role as the ultimate judge of humanity.

6. Authority in His Sacrificial Role: The Son of Man's authority is also evident in His sacrificial mission. In Mark 10:45, Jesus states, "For even the Son of Man did not come to be served, but to serve, and to give His life as a ransom for many." . His authority is exercised in humility and self-giving love, fulfilling the redemptive plan of God.

Theological Implications

The authority of the Son of Man is central to Christian theology, affirming both the divinity and humanity of Jesus Christ. His authority is not only a testament to His identity as the Messiah but also a demonstration of His unique role in God's redemptive history. The title "Son of Man" thus serves as a bridge between the Old Testament prophecies and their New Testament fulfillment in the person and work of Jesus Christ.
