Wow, this looks like a topic I could get into. I'm new with this forum, but not new with this debate....
This is an excellent scripture to debunk trinitarianism. Since trinitarianism holds the position that "Father, Son and Holy Spirit" are co-equal, co-eternal, ect...
However this scripture in no way debunks the Biblical position of the deity of Jesus. It's simply revealing the fulfillment of the purpose and role of the "Sonship". We knew the fulfillment of this position, would be a moment in time, when God said, "Sit at My right hand UNTIL I make your enemies your footstool". (Psalm 110:1)
"UNTIL" signifies a moment in time.
1 Cor 15: 24. "Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power."
Ephesians 5:27 sheds more light on the subject "That he [Christ] might present it to HIMSELF a glorious church…"
When we understand the very clear and very obvious biblical position that as a Man, Jesus has a dual nature, scriptures such as this, don't pose any problem or cause any contradiction to the biblical doctrine of the deity of Jesus.
