Apotheoun,
Can you expand on this? I have read Metr. Zizioulas say that the Father is the cause of the Godhead. What is the distinctions between the term Godhead and God? It seems like a contradiction of terms to say that the Father - who is God - is the cause of the Godhead.
Metr. Zizioulas is simply stating what the Eastern Fathers always stated, i.e., that the Father is the source of divinity (
pege theotetos), the cause of the divine essence (
ousia) itself; for as St. Gregory Palamas explained, “When God was speaking to Moses, He did not say, ‘I am the essence,’ but ‘I am who I am.’ It is not, therefore, He-that-is who comes from the essence, but the essence comes from He-that-is, for He-that-is embraces in Himself all being.” [St. Gregory Palamas, Triads, Part III, 2, 12]. In other words, God the Father is the Father of His own essence, while also being the sole cause of the hypostasis of the Son by generation (
gennatos), and the hypostasis of the Spirit by procession (
ekporeusis).
