Why Is Jesus Called the "Son of Man"?

@SincereSeeker
i was waiting for this topic, my brother, this is what I feel.
The term "Son of Man@ (huios tou anthropou in greek and ben adam in hebrew) is linguistically polyvalent, oscillating between human and divine connotations. In hebrew usage, ben adam denotes a human being, as seen in God’s address to Ezekiel 2:1, emphasising mortality and creatureliness. However, its apocalyptic inflection in Daniel 7:13-14- where “one like a son of man” receives eternal dominion, imbues it with theophanic significance. In Catholic and Orthodox hermeneutics, this duality is not dichotomous but synergistic, reflecting the Chalcedonian definition of Christ’s two natures (divine and human) united without confusion or separation. Patrisitic theoloigan like St. Cyril of Alexandria interpret “Son of Man” as kenotic self-designation, whereby the Logos veils His divine glory in human flesh, yet retains thearchich perogatives (like authority to forgive sins). The terms flexibility allowed Jesus to reveal His identity progressively, inviting faith while subverting messianic expectations of political triumphalism prevalent in first-century Judaism.
The Sciptural underpinning of "Son of Man@ is rooted in Daniel 7:13-14 where a human-like figure approaches the Ancient of Days, receiving “dominion, glory and kingdom” that is everlasting. Jesus appropriates this title to assert His messianic identity.
Mark 2:10 we see
“The Son of Man has authority on earth to forgive sins”
SHowing revealing divine perogative, as only God forgives sins (Psalms 130:4)
Mark 8:31
“The Son of Man must suffer many things… and be killed, and after three days rise again”
linking the title to the suffering servant of Isaiah 53:3-12 fulfilled in Christ’s passion.
Mark 14:62:
“You will see the Son of Man seated at the right hand of Power, and coming with the clouds of heaven” directly showing Daniel 7 to affirm His eschatological return and divine authority.
John 5:27
“He has given Him authority to execute judgment, because He is the Son of Man”
grounding His judicial role in His incarnate nature.
In apostolic exegesis, these texts underscore Christ;s hypostatic union, his divine and human nature in one person. The “Son of Man” title integrates His kenotic condescension (Philippians 2:7-8) with His eschatological exaltation (Acts 1:11). The Church Father, such as St. Athanasius saw this as affirming the theandric nature of Christ’s actions, where His human suffering and divine power cohere in the economy of salvation.
Lets talk abt Hypostatic Union and Communicatio Idiomatum
THe “Son of Man” title reveals CHrist’s hypostatic union, where divine and human natures are united in the single hypostasis of the Logos (Chalcedonian Definition 451AD). Unlike Oneness-pentecostal, which posits Jesus as the singular God without distinct persons, catholic/orthodox theology affirms the Logos as the Second Person of the Trinity, who assumes humanity without compromising divine immutability. St.Cyril of Alexandria articules this as the unio personalis, where the Son fo Man is the theos anthropos (God-man) whose human nature is the instrument of divine action (took me one day to learn about this segment before, believe me, its worth it)
The communicatio idioatum allows attributes of one nature to be predicated of the other in the person of Christ. Thus the Son of Man forgives sins (divine act, Mark 2:10) and suffers (human act, Mark 8:31), manifesting the indivisible unity of His natures. This counters Nestorianism.
Soteriological Mediation and Theandric atonement is another part I want to talk about.
THe Son of Man’s humanity is soteriologically constitutive, enablign Him to serve as the mediator between God and humanity (1 Timothy 2:5). His kenotic incarnation (Philippians 2:7) allows Him to offer Himself as the hilasterion (propitiatory sacrifice, Romans 3:25) satisfying divine justice and reconciling humanity to Go (2 Corinthians 5:19). St Anselm’s satisfaction theory and St.Greogory Palamas’ emphasis on theosis converge here: Christ’s human obidence as the Son of Man merits salvation for humanity, while his divine anture divinizes believers through sacremental participation.
In Apostolic Theology, the sacrement particularly Baptism and Eucharist are theandric extensions of the Son of Man’s work. Baptism unites believers with Christ’s death and resurrection (Romans 6:3-4), while the Eucharist actualizes His sacrifical presence (1 Corinthians 11:24-25). Unlike Oneness emphasis on baptism in Jesus’s name as a salvific necessity, Catholic/Orthodox theology views these as grace-conferring mysteries, not meritorious works, aligning with synergistic grace (meaning God’s initiative-human response).
Then coming to Eschatological Teleology, we need to talk about recapitulation and parousia. The Son of Man’s eschatological role, rooted in Daniel 7 positions Him as the eschaton’s arbiter, exercisign krisis (judgement, John 5:27) and inaugraiting the parousia (second coming, Matthew 24:30). St Irenaeus’s concept of recapitulation is pivotal, as the Son of Man, Christ sums up all humanity restoring creation’s telos by uniting it to God (Ephesians 1:10). His human nature ensures a just judgement for He has experienced human frailty as in Hebrews 4:15.
In Catholic/Orthodox eschatolog, the Son of Man’s return consummates the apokatastasis panton (meaning restoration of all things, as in acts 3:21) transforming creation into the new heavens and earth (Revelation 21:1).
THen at last we gonna talk about Theanthropic recapitulation and perichoresis (my favourite topic, especially every Christian needs to know about perichoresis)
The Son of Man embodies theanthropic recapitulation, where Christ, as the Second Adam ( 2 Corinthians 15:45-47) restores humanity’s vocation through His obedience and victory over sin. This integrates St.Irenaeus’ recapitulo with St.Maximus the Confessor’s perichoresis (now perichoresis means mutual indwelling) of Christ’s natures, where human and divine operations interpenetration without confusion (goosebumps coming, this is the beautiful meaning of Periochoresis, Lets cry together, Lets Praise God togother, along with the Angels and Archangels, we praise God, we raise up a hymm of praise to him who creates and gives breath of life, He who crushed the head of the serpent, we praise him, so immense is your glory O God, its a marvel, we are unable to grasp it, O Adonai, hearken to our prayers.)
The Son of Man’s life i.e. born, sufering, dying, rising recpaitulates human existence divinizing it thorugh His divine energeia ( I talked more about this on Oneness vs Trinity debate, divine energeia is a whole another topic, energeia means activity)
Apostolically, this grounds the sacramental economy, i.e. baptism and Eucharist are perichoretic encounters with the Son of Man, enabling believers to participate in His divine life (2 Peter 1:4). This is the point i was waiting to make, isnt it amazing my brothers, O MAN, im going to faint, its too much for me to grasp.
@SincereSeeker, im waiting to learn more from you.
