Assuming you would say that "origin" does not negate the concept of "eternalness", of what import is origin in describing a co-eternal and co-equal God?

The origin is understood to be eternal, i.e. the Son is eternally  begotten by the Father, and the Spirit eternally proceeds form the Father. It's like saying the water wells unceasingly from the eternal origin.

But the existence of both the Son and the Spirit (and therefore the Godhead, the Trinity) is eternally caused by the Father who is himself un-caused; hence the monarchy of the Father.

But the existence of both the Son and the Spirit (and therefore the Godhead, the Trinity) is eternally caused by the Father who is himself un-caused; hence the monarchy of the Father.

This goes with my recent post to Kolo about the Chrysostom article. MY existence was caused by God, so how can the existence of any of the Trinity said to be caused? To say "caused" means there was a time of non-existence.
