Question
How can God be both unknowable and truly known?
This is the central tension of Orthodox theology. God is incomprehensible in His essence — no creature can grasp what God is in Himself. And yet the mystics and saints genuinely know God — not merely know about Him, but encounter Him, participate in Him, are transformed by Him. The distinction between God's essence and His energies is the Orthodox answer to this tension.
The essence is what God is in Himself — uncreated, infinite, beyond all creaturely comprehension. The energies are what God communicates of Himself — His life, love, wisdom, holiness — reaching outward from the essence into creation. The energies are truly God: not a created go-between, not a diminished form of God, but God genuinely giving Himself to creatures. The difference is between God as He is in Himself and God as He gives Himself to us.
The teaching
God gives Himself truly — without surrendering His mystery
The energies are not a substitute for God. They are God. When you encounter divine love, you are encountering God — not a created representation of God. When you participate in divine life through prayer and the sacraments, you are participating in something uncreated. The essence remains incomprehensible; but the energies are genuinely received. This is how God can be both totally beyond us and totally for us — at the same time.
Examples from Scripture: God is light (1 John 1:5) — the divine light is an energy, genuinely God, genuinely communicated. God is love (1 John 4:8) — the divine love is an energy, genuinely God. God is life (John 14:6) — the divine life is an energy. These are not metaphors. They are descriptions of the energies through which the incomprehensible God genuinely reaches creation.
We know God from His energies, but we do not claim to draw near to His essence itself. His energies come down to us, but His essence remains inaccessible.
Basil's formula is exact. Two things are held together: real knowledge (from His energies) and real incomprehensibility (His essence remains inaccessible). Neither is sacrificed for the other. We know God genuinely — not merely in symbols or metaphors. And we do not exhaust Him — the essence remains beyond us. This is not contradiction but the precise description of what relation with an infinite God is like.

Holy Scripture
"His divine power has granted to us all things that pertain to life and godliness... so that through them you may become partakers of the divine nature."
2 Peter 1:3–4
"Now this is eternal life: that they know you, the only true God, and Jesus Christ whom you have sent."
John 17:3
Theosis
What it means to participate in the life of God
Theosis — deification — is the goal of the Christian life: the full participation of the human person in the divine life. It does not mean becoming God in essence — the creature does not become the Creator. It means becoming God by grace and participation — receiving divine life, being transformed by it, becoming increasingly transparent to it. The saints are those in whom this process is most advanced.
