Eastern Catholic theology understands Christ's saving work through several complementary models, with particular emphasis on the Christus Victor framework: Christ's death and resurrection constitute a cosmic victory over sin, death, and the devil, restoring human nature and opening the way to theosis. Eastern patristic sources frequently present the Incarnation itself as salvific, since the Son of God united himself to human nature in order to heal and transform it.

While Eastern Catholics in communion with Rome accept the Catholic Church's broader teaching on atonement, Eastern theological tradition has historically been less focused on satisfaction or penal substitution theories (associated with Anselm of Canterbury) and more on recapitulation (associated with St. Irenaeus) and deification. Christ bore our death and corruption so that we might share in his divine life. These emphases coexist within the broader Catholic theological tradition.
