Before the Incarnation, “No one could see the Father but the Lamb…Then the Word became Flesh, received from the Father…so that all might see their King, that the Father’s light might be gathered in the Flesh of Our Lord, and from His Flesh strike into us like lightning, so that man might attain to eternal life, wrapped in the Father’s light.”

S. Irenaeus, Adv. Haer. 2.214
