Eastern and Reformed Views on Christ and the Trinity
The Athanasian Creed articulates the ecumenical consensus: "we worship one God in Trinity, and Trinity in Unity; neither confounding the persons nor dividing the substance" [6]. This formulation, shared across Eastern and Western Christianity, affirms three distinct persons (Father, Son, Holy Spirit) in one divine essence. Yet beneath this shared confession lie significant differences in how Eastern Orthodox and Reformed traditions articulate the relationship between Christ's natures and the Trinity's operations.
The Person of Christ
John of Damascus, representing Eastern theology, argues that "things that have the same essence have also the same energy," linking the question of Christ's energies directly to Trinitarian personhood [1]. The Eastern tradition distinguishes between essence and energies, maintaining that Christ possesses two energies corresponding to his two natures—divine and human—without dividing his person. This contrasts with those who would collapse energy into a single operation, which Damascus warns would logically require collapsing the persons themselves [1].
Reformed theology, articulated by Calvin, insists that Christ is "our Lord and the true Son of God, even according to his humanity, though not by means of his humanity" [4]. Calvin rejects Nestorius's "double Christ" while maintaining the integrity of both natures "united, but not confused" [4]. Charles Hodge develops this further, describing Christ's humanity not as "wholly dissevered from that of Adam" but as Adam's humanity "raised to a higher character" through union with the divine nature [2]. This union enables Christ to communicate his life "substantially to the soul," constituting the Church as his mystical body [2].
Trinitarian Access and Mediation
Both traditions affirm Trinitarian mediation in salvation, though with different emphases. Adam Clarke's commentary on Ephesians 2:18 presents the cooperative work: "through him—Christ Jesus, we both—Jews and Gentiles, have access by one Spirit—through the influence of the Holy Ghost, unto the Father" [5]. Jamieson-Fausset-Brown notes that "the grace of Christ" comes first in Paul's benediction, "for it is only by it we come to 'the love of God' the Father," demonstrating that "in this Trinity none is afore or after other" [7].
Augustine's exegesis of the imago Dei illustrates Western Trinitarian thought: when Scripture says "God made man in the image of God," we understand "the one and selfsame Trinity itself, who is one God, and after whose image man is made" [3]. This reflects the Western tendency to emphasize divine unity, while Eastern theology more readily distinguishes personal properties and operations within the Godhead.

Indeed, the holy Fathers have maintained with one voice that things that have the same essence have also the same energy. But further, if personality is introduced along with energy, those who divine that neither one nor two energies of Christ are to be spoken of, do not maintain that either one or two persons of Christ are to be spoken of.”
