Since they share all the same divine attributes they only differ in role or function like you pointed out. Sort of like in a marriage where we are equal as humans/persons but different in our roles in the family unit. The wife submits to the husband and the Son does with the Father in the Trinity and the Holy Spirit does with both the Father and the Son.
hope this helps !!!
So before the incarnation there were three co equal co eternal members of the Godhead ... How did they decide which one was going to play the role of son, which one the Father, which one Spirit? Toss a coin?
Seriously. They are only role playing? Like a show? A metaphor?
So, according to the modem church in order to accomplish the plan of salvation and to enable man to better understand the issues involved, the members of the deity took certain positions? Questions....
Where in scripture is there any suggestion of such a role playing concept being enacted by God?
When the Bible says that God gave His only begotten Son, what reason is there not to believe that God actually had a literal preincarnate Son to give?
If Jesus is the literal Son of His Father and Through whom the Father created all things as scripture reveals, why is His divinity questioned?
Why is a concept which arose in the 4th century considered a better means by which to ascribe divinity to Christ than the plain concise declaration of Peter, "thou art the Christ, the Son of the Living God?".
Why is it necessary to make the Father and the Son of equal ages (if you believe in a preincarnate Son) in order to fully establish the divinity of Jesus particularly in the light of Colossians 2:9?
And finally, why can we not simply accept the Bible testimony regarding the one true God, instead of denying, reasoning, and teaching something contrary?
KJV 1 Corinthians 8:6
6 But to us there is but one God, the Father, of whom are all things, and we in him; and one Lord Jesus Christ, by whom are all things, and we by him.
KJV John 17:3
3 And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.
KJV Ephesians 4:6
6 One God and Father of all, who is above all, and through all, and in you all.
KJV 1 Corinthians 11:3
3 But I would have you know, that the head of every man is Christ; and the head of the woman is the man; and the head of Christ is God.
KJV Ephesians 1:15-17
15 Wherefore I also, after I heard of your faith in the Lord Jesus, and love unto all the saints,
16 Cease not to give thanks for you, making mention of you in my prayers;
17 That the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of wisdom and revelation in the knowledge of him:
To quote a late 19th century scholar and historian...
"
There were some very early that turned the doctrine of the Trinity into tri- theism, and instead of three Divine persons, brought in three collateral, coordinate, and self originated beings, making them 3 absolute and independent principles... Which is the most proper notion of 3 gods.
