It doesn't help your course in any way, if anything, it shows two beings. You have to show us where the scripture says two persons in one being, John 1:1 is not the verse for you.
We know how the logos became flesh and we know how He was with God, there's nothing more than:
Malachi 3:
1Behold, I will send my messenger, and he shall prepare the way before me: and the LORD, whom you seek, shall suddenly come to his temple, even the messenger of the covenant, whom you delight in: behold, he shall come, said the LORD of hosts.
God Himself became flesh, nothing like a part of Him coming and leaving other parts. Pie doctrine can not describe God.
