Theosis
Salvation includes real participation in the divine life by grace.
What it is: Theosis designates the participation of the human being in the divine life by grace.
How the tradition understands it: Salvation is seen as healing, illumination, and communion with God, and not only as juridical forgiveness. Christ assumes humanity to restore it and elevate it.
Basis and context: The language of deification is deeply associated with the Greek Fathers and Orthodox spirituality.
Debates and variations: Compared with modern Western Christian currents, the emphasis and terminology can sound unusual, but they occupy a central place in the Eastern tradition.
