João 14

João 14:28

If we say that the Father is the origin of the Son and greater than the Son, we do not suggest any precedence in time or superiority in nature of the Father over the Son (for through his agency he made the ages) or superiority in any other respect except causation. And we mean by this that the Son is begotten of the Father and not the Father of the Son, and the Father naturally is the cause of the Son. So then, whenever we hear it said that the Father is the origin of the Son and greater than the Son, let us understand it to mean in respect of causation. — ORTHODOX FAITH 1.8
