Again, from Gorman:
Because the faithful and loving crucified Christ is the image and self-revelation of God, the paradoxical process of justification by co-crucifixion, or resurrection through conformity to the crucified Christ, means that the pisteuontes (“believers”) are those who are becoming like God and thus experiencing the process of theosis inasmuch as they embody the symbiosis of fidelity and love found in the Son of God.
What does that mean? Inasmuch as Christ’s faithful and loving death reveals the faithfulness and love of God, and justification is participation in that death, justification is participation in the faithfulness and love of God. It is, thus, a process of deification or theosis. The cruciformity that is constitutive of justification is actually theoformity, or theosis . . . This means also that to become the righteousness or justice of God in Christ is theosis. This is not primarily an individual experience, but a corporate one of communal theosis–we become, in Christ, the righteousness/justice of God. (p. 90-91)
