2 Peter 1.3-8 [3] His divine power has given us everything needed for life and godlikeness, through the knowledge of him who called us by his own glory and goodness. [4] Thus he has given us, through these things, his precious and very great promises, so that through them you may escape from the corruption that is in the world because of lust, and may become participants of the divine nature. [5] For this very reason, you must make every effort to support your faith with goodness, and goodness with knowledge, [6] and knowledge with self-control, and self-control with endurance, and endurance with godlikeness, [7] and godlikeness with mutual affection, and mutual affection with love. [8] For if these things are yours and are increasing among you, they keep you from being ineffective and unfruitful in the knowledge of our Lord Jesus Christ.
🗝️ Key Concept: Theosis
What is the ultimate goal of salvation? Is it simply a ticket to heaven, an escape from punishment, or a legal declaration of forgiveness? The Christian tradition, especially in its early and Eastern forms, offers a far more breathtaking and transformative vision. The goal is not just to be saved from something, but to be saved for something: To be so filled with the life of God that we ourselves become godlike. This is the shocking and beautiful doctrine of Theosis.
The word Theosis (also known as deification or divinization) comes from the Greek word theos, meaning "God." It is the process of becoming, by grace, what Christ is by nature. This was not a fringe idea but was the assumed understanding of salvation for nearly all major Christian thinkers in the first centuries. As St. Athanasius famously declared, “God became human that humans might become divine.” This doesn't mean we usurp God or become individual deities. Rather, it means we are invited to become participants in the divine nature, to be so fully integrated into the life of the Trinity that we radiate God’s own love and glory.
In the Eastern Orthodox tradition, this is understood through the distinction between God’s unknowable essence and God’s knowable energies. We can never become God in His transcendent essence, but we can fully participate in His immanent, life-giving energies. Think of an iron rod plunged into a fire. The rod never becomes the fire itself, but it takes on the properties of the fire, glowing white-hot with its light and heat. In the same way, through Theosis, our human nature is permeated by the divine life, yet we remain distinctly ourselves. This is the ultimate expression of a panentheistic vision where God is in all things, inviting all things to share more fully in the divine life. It is our destiny to be caught up in the divine dance of the Trinity, sharing in the love that flows eternally between the Father, Son, and Holy Spirit.
