The Divinity
of Christ

Definition of Terms:

  • Trinity:  the belief in one God who exists as three distinct persons: the Father, the Son (Jesus Christ), and the Holy Spirit. These three persons are understood to be co-eternal, co-equal, and consubstantial, meaning they share the same divine essence.
  •  Consubstantial:  a term used to describe the Trinity of the Father, Son (Jesus Christ), and Holy Spirit are of the same substance or essence. It signifies that they share a fundamental unity of being, possessing the same divine nature. The term “consubstantial” emphasizes the essential oneness and equality of the three persons within the Godhead, affirming that they are not separate entities but inseparably united in their divine essence.

During the second to fifth centuries, debates regarding the relationship between Christ’s human and divine natures were central within the early church. These discussions greatly influenced the first seven Ecumenical Councils that followed. While it took centuries to fully develop the precise understanding of Christ’s nature and his relation to the Father, the fundamental teaching that Jesus Christ is both fully human and fully divine can be implicitly reasoned from Scripture.

Scripture provides numerous references to Jesus as God, such as John 1:1, where it states, “In the beginning was the Word, and the Word was with God, and the Word was God.” Additionally, in Matthew 1:22-23, Jesus is called “Immanuel,” meaning “God with Us.” Another clear affirmation comes from John 20:28-29, when Thomas declares, “My Lord and My God!” Jesus Himself emphasizes His inseparability from the Father, stating, “I and the Father are one” (John 10:30, John 10:37-38, John 14:7-10).

Moreover, Jesus is attributed with the same titles as God the Father. Both are referred to as the first and the last (Isaiah 44:6, Revelation 22:13). Jesus also identifies Himself as “I Am” in John 8:58. In Mark 2:1-12, during the healing of the paralytic, Jesus claims the power to forgive sins, a divine prerogative. The scribes recognize this, questioning, “Who can forgive sins but God alone?” (Mark 2:6). Furthermore, Jesus demonstrates His divine knowledge by reading their thoughts, validating His claim. Scripture consistently supports Jesus’ divinity.

The early Church relied on the Traditions of Apostolic Teaching and the Authority of the Magisterium to address theological debates, including the nature of Christ. Many heresies arose during this time, such as Adoptionism, Modalism, Docetism, Arianism, Nestorianism, Monophysitism, and Miaphysitism. Church Councils were convened to resolve these controversies, condemning views that deviated from the orthodox teachings agreed upon by the larger Catholic Church.

These Councils resulted in early schisms within the Church, with the Assyrian Church rejecting the Council of Ephesus and the Oriental Orthodox Church rejecting the Council of Chalcedon. However, recent efforts toward reunification have been made between leaders of the Eastern Orthodox, Oriental Orthodox, and Assyrian Church of the East, aiming to address historical differences over terminology rather than intended meaning. While Lutheran, Anglican, and Reformed Churches recognize the first four Councils, there is a growing number of denominations that reject the dual nature of Christ.

Critics have raised rationalist objections, citing verses like John 14:28, where Christ states, “The Father is greater than I,” to argue for the Son’s subordination to the Father. However, the doctrine of the Incarnation maintains that the Son, in His human nature, is lesser than the Father, while His divine nature remains undiminished. Rationalists also claim that the Incarnation implies a change in God’s nature, but the Church explains this through the concept of the “hypostatic union.” In the Incarnation, the second person of the Trinity acquires a human nature while retaining the divine nature. The divine and human natures of Christ are distinct yet united within the one person of Christ. This union occurred in the human nature assumed by Christ, not in God’s unchanging divine essence.

The Athanasian Creed, utilized by Christian churches since at least the sixth century, articulates these beliefs, affirming that Christ is fully God and fully human, with a rational soul and human flesh. He is equal to the Father in His divinity but lesser than the Father in His humanity. Christ is not two separate entities but one, as God took humanity upon Himself without transforming His divinity and by maintaining the unity of His person.

He himself is before all things, and in him all things hold together. He is the head of the body, the church; he is the beginning, the firstborn from the dead, so that he might come to have first place in everything. For in him all the fullness of God was pleased to dwell, and through him God was pleased to reconcile to himself all things, whether on earth or in heaven, by making peace through the blood of his cross. And you who were once estranged and hostile in mind, doing evil deeds, he has now reconciled in his fleshly body through death, so as to present you holy and blameless and irreproachable before him.”

[thinking] that we confess that there is another God, and that he is mortal. . . .

“But those who say, ‘There was a time when he [the Son] did not exist,’ and ‘Before he was born, he did not exist,’ and ‘Because he was made from non-existing matter, he is either of another substance or essence,’ and those who call ‘God the Son of God changeable and mutable,’ these the Catholic Church anathematizes” (Appendix to the Creed of Nicaea [A.D. 325]).

Non-Catholic Quotes:

Novatian
“If Christ was only man, why did he lay down for us such a rule of believing as that in which he said, ‘And this is life eternal, that they should know you, the only and true God, and Jesus Christ, whom thou hast sent?’ [John 17:3]. Had he not wished that he also should be understood to be God, why did he add, ‘And Jesus Christ, whom thou hast sent,’ except because he wished to be received as God also? Because if he had not wished to be understood to be God, he would have added, ‘And the man Jesus Christ, whom thou hast sent;’ but, in fact, he neither added this, nor did Christ deliver himself to us as man only, but associated himself with God, as he wished to be understood by this conjunction to be God also, as he is.” (Treatise on the Trinity 16 [A.D. 235]).
