Theosis

The Orthodox teaching that human beings are called to be transformed by God's grace into his likeness, sharing in the divine life without becoming God in essence. It frames salvation as union with God rather than a merely legal verdict.

Related: Divinization by grace, Image and likeness of God, Synergy
Image and likeness of God

The biblical claim that humans are made in God's image (Genesis 1:26–27). Patristic writers distinguish the given image from the likeness that must be freely acquired through virtuous living and grace.

Related: Theosis, Synergy, Freedom of the will
Synergy

The cooperation of human freedom with divine grace in salvation and growth in holiness. Orthodox theology rejects both pure human self-salvation and a grace that overrides the will, insisting that God invites and the person responds.

Related: Theosis, Freedom of the will, Prevenient grace
Freedom of the will

The God-given capacity of humans to choose, including the capacity to accept or refuse grace. It grounds moral responsibility and explains why love toward God must be freely offered rather than compelled.

Related: Synergy, Ancestral sin, Image and likeness of God

A state of inner freedom and calm in which the passions no longer dominate the person. It is a goal of ascetic struggle, understood as loving detachment rather than indifference or the absence of feeling.
