Christ's Dual Identity in Trinitarian Theology
The dual identity of Christ, often referred to as the hypostatic union, is a foundational concept in Trinitarian theology, asserting that Jesus Christ is both fully divine and fully human. This mystery, though revealed, is not entirely comprehensible by human reason [2].
Scripture presents God as one, yet subsisting in three distinct persons: Father, Son, and Holy Spirit [1]. Jesus, as the Son, is understood to possess the fullness of the Godhead [5]. The Apostle Paul highlights this mystery, stating, "And without controversy great is the mystery of godliness: God was manifested in the flesh" (1 Timothy 3:16) [2]. This manifestation involves the incarnation of Christ, his birth of a virgin, and the union of divine and human natures in his person [2].
The divine nature of Christ is affirmed through passages that speak of the Father giving the Son the Spirit without limit, illustrating Jesus' divinity [7]. The Apostle John presents the one God as three persons, further emphasizing Christ's divine identity within the Trinity [7].
Simultaneously, Christ's humanity is crucial. He is depicted as the "second Adam," founding a new humanity that is spiritual and heavenly, in contrast to the natural and earthly humanity represented by the first Adam [3]. This dual nature means that Christ's human body is where the Godhead dwells in the most eminent and exalted manner [5].
The Trinitarian benediction found in 2 Corinthians 13:14, "The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all," demonstrates the distinct yet unified roles of the three persons of the Trinity, with Christ's grace often presented first as the means by which believers access the love of God the Father [4]. The order of persons in such passages varies, indicating that "in this Trinity none is afore or after other," as articulated in the Athanasian Creed [4]. John Calvin, in his commentary on Genesis, acknowledges the Trinitarian distinctions while emphasizing that a definition of the image of God should rest on a firm scriptural basis [6].

- Easton's Bible Dictionary “Easton's Bible Dictionary: Trinity — A word not found in Scripture, but used to express the doctrine of the unity of God as subsisting in three distinct Persons. This word is derived from the Gr. trias, first used by Theophilus (A.D. 168-183), or from the Lat. trinitas, first used by Tertullian (A.D. 220), to express this doctrine. The propositions involved in the doctrine are these: 1. That God is one, and that there is but one God (Deut. 6:4; 1 Kings 8:60; Isa. 44:6; Mark 12:29, 32; John 10:30). 2. That the Father is a distinct divine Person (hypostasis, subsistentia, persona, suppositum int”

Adam represents the natural (physical) body and Christ the spiritual (resurrection) body. See also 15:21-22; Rom 5:12-21. 15:45-46 Just as Christ’s life-giving Spirit supersedes the natural life, the spiritual body will supersede the physical body.”
