What is Theosis?

The Greek word "theosis" (θέωσις) means deification or divinization. In Eastern Christian theology, it refers to the process of becoming like God, or attaining likeness to or union with God.

Theosis is the ancient Christian invitation to become one with God — not in theory, but in experience. It is the lifelong transformation of the human person through love, grace, and participation in the divine life.

Theosis is the divinely intended destiny of human beings: to be united with God through the incarnation of Christ. This is not an artificial elevation but the natural fulfillment of humanity’s purpose. Grace and nature are not opposed but integrated. In Christ, the union of God and man is both accomplished and offered to all.

Theosis is the full realization of what it means to be human: to become by grace what God is by nature.

  • God created the world specifically so that Christ could enter it, uniting divine and human natures, and enabling humanity to share in divine life.

    “God became human so that humans should become God.” —St Athanasius of Alexandria

    This statement, echoing the Church Fathers, expresses the central conviction of theosis: that God’s purpose in creating is to bring creatures into union with himself.

  • Theosis is not a supernatural add-on to human existence, but the fulfillment of what humanity was always meant to be. The Fall introduced alienation and corruption, but it did not erase the underlying orientation of human nature toward God.

  • Theosis is not a strange or optional idea—it is what human beings are for. Humanity is not complete apart from union with God. Christ, as both divine and human, is the archetype of this union. He does not merely offer moral improvement or legal justification but shares his divine life with us.

    The incarnation reveals this: God does not remain distant but enters creation to bring creation into himself. Our participation in divine life is possible because Jesus is the God who is always already united to humanity.

  • In theosis, we do not become God in essence, but we become partakers in the divine energies—that is, in God’s life and love. This distinction, often emphasized in Eastern theology (especially by the likes of St. Gregory Palamas), preserves the Creator-creature distinction while still affirming the real and transformative union with God.

    “All that God is, except for an identity in being, one becomes when one is deified by grace.” —St Maximus the Confessor

  • The human being is, by nature, drawn toward God as its telos (end). This is not simply an abstract intellectual longing, but a deep hunger for union with Love itself. Theosis is the journey of that hunger being fulfilled through divine initiative and human participation.

    “Our hunger for transcendent wholeness propels us toward the triune Creator who will be all in all.” - David Bentley Hart

    This movement is dynamic, relational, and rooted in the Trinitarian life. We are made for communion, and God persistently draws us into that communion.

The Resurrection Icon, also known as the "Anastasis" or "Harrowing of Hades," depicts Christ descending into Hades (the realm of the dead) to rescue Adam and Eve, symbolizing his victory over death and his redemption of all humanity.
