The Holy Spirit has always existed as the power and influence of the Father. It NEVER became a third person of a trinity. The logos did indeed become a person, but before that it was the Father's spoken words, thoughts, plans, etc. Even after the logos was made flesh, that flesh was not the second person of a fictitious trinity. He is the Son of the only true God.
In the O.T. the Spirit was spoken of as the Spirit of God. When Jesus said it was good for Him to go away so that the comforter could come,,,what did He mean?
Why would He have said that if the Spirit of God existed even in the Old Testament? Perhaps Jesus meant it in a new way, a more "real" way. Why can't God do whatever He wants to do if He was even able to create the entire universe?
Maybe God wanted to be a more personal God...Maybe the "persons" of the Trinity are not how we understand it since we can only speak in human terms...
You yourself stated above that the Word of God became Jesus -- this is what I've been saying all along, only with words that are difficult for us humans to understand. This is why there was so much debate about the Trinity.
Jesus was understood to be God from soon after the Ascension,,but how could He be God if there is only ONE God? So human terms had to be made...thus the word begotten, which only means unique and not "made" or "born of".
Thus the idea of the Trinity, understand it how you may.
The Word became Jesus.
The Breath became the Holy Spirit...God's spirit.
He can authorize them to do so. He did not authorize Catholic priests to do so.
I'm apparently not explaining myself correctly and I'm not really too interested in this. The question would then become...why would the Apostles be authorized to forgive sin and not those that came after them??? (since those that came after them are human just as they were) Different discussion.
You just took a giant leap from Yeshua forgiving sin because he was authorized to do so, to him forgiving sin because he is God. No. He forgave sin because he was GIVEN that authority by God.
So Jesus also gave the authority to forgive sin to the Apostles...
Since only God can give this authority, doesn't this speak to Jesus being God?
