So in John 17:3 the Son is not the Only true God?
John 17:3
Now this is eternal life: that they know you, the only
true God, and Jesus Christ, whom you have sent.
That still does not mean the Son is the Father, and the Father is the Son.
The Son is God.
The Father is God.
But the Son is God having two natures in union.
God and Soul.
The Father is solely God. No other nature in union.
The Father, as is, alone, is imperceivable to man.
The Father transcends human perception.
The Son uses His human nature to take what he uniquely knows about God, and translate God to man in human terms.
The Father as God does no such thing.
He works through the Son to make Himself known.
That is why Jesus said...
"No one comes to the Father except through me. "
The Son is God actively making the Father knowable to man by interpreting what we can not perceive about God,
and interpreting God to us in human terms.
John 1:18
No one has ever seen God, but the one and only Son, who is himself God
and is in closest relationship with the Father, has made him known.
[He has revealed Him and brought Him out where He can be seen;
He has interpreted Him and He has made Him known].
