What is even more unfortunate is the men promote a doctrine developed by men that cannot be supported when the whole word of God is taken into account.
Jesus gives eternal life to those who follow Him because the Father gives them to Him as Jesus explained in the Scripture you quoted. Taken in context your proof text disproves your thesis.
Reread those Scriptures you posted that state the Son is the first-born of creation and then tell me that the Son was not the first created spirit. God was not born, He existed before the Son was born spiritually or physically.
