You are running from the question
So you don't appreciate being enlightened when it does not suit you. Got it.
the verse was saying for them there is but one God and one Lord
God being the Father
Christ being the lord
So was Christ their only Lord ?
Paul didn't say Christ is the only Lord.
He said we have two things: one of these plus one of those, ONE God plus ONE Lord.
Just like ancient Israel had one God, Yahweh, and one Lord King David.
Answer the question and don't divert
Nothing to divert.
Or did you really mean you wanted to wedge me into providing an answer which suits your creedal lord?
