Jesus saith to him: Have I been so long a time with you; and have you not known me? Philip, he that seeth me seeth the Father also. How sayest thou, Shew us the Father? Do you not believe, that I am in the Father, and the Father in me? The words that I speak to you, I speak not of myself. But the Father who abideth in me, he doth the works (John 14: 9-10).
Have some common sense man!
Jesus had all of God's authority.
Jesus so perfectly represented God his Father that he was ables to tell people that if you've seen me, you've seen him.
He certainly wasn't trying to pass himself off as the Father!
It is not much different than a Father-Son business with the son running things and telling people that they don't need to see dad, he can take care of it all.
Remember what Jesus told his disciples?
Jhn 14:12 Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater [works] than these shall he do; because I go unto my Father.
So believers are going to do the same works that Jesus did and even greater.
If Jesus was God, he was promising that his believers would then do greater works than God.
But that isn't what he was promising, was it?
The words that I speak to you, I speak not of myself. But the Father who abideth in me, he doth the works
How that becomes a defense for the trinity is... quite odd. :-/
