As I've said multiple times the trinity doctrine is an evolved doctrine. It didn't spring full born into existence. There were starts and stops. There were debates and discussions. There were penalties and charges of heresy. It evolved over time. And that's fine IF you want to place your faith, confidence and belief in post biblical church fathers. Knock yourself out. But that doesn't make the trinity doctrine scriptural and nobody in bible times knew it or believed it.
Also some of those passages have little to do with the trinity theory but only mention a holy spirit in the same breath as the father and son. That really proves nothing *unless* we already have a presupposition that the Godhead is composed of three beings...which again scripture shows it is not.
Are you a Mormon?
Except you have been shown multiple times now that assertion is NOT true. If "nobody in bible times knew it or believed it" then WHY are there many, many verses in Scripture that say the Holy Spirit DOES exist and we have writings from early Christians that affirm the same prior to the Council of Nicea? And we don't have a lot more writings that might have been written simply because the material they may have written on deteriorated after all this time.

Except those passages speak about the Holy Spirit as a person (HE) apart from the Father and the Son, as proceeding FROM the Father and the Son, that does things and that things can be done TO Him. You ought to acknowledge that you have your OWN presuppositions prejudiced against the Holy Spirit as God - probably taught to you by some denomination - and you made up your mind regardless of what has been shown to you from Scripture that disproves it.
I respect your right believe what you want on this and I would never force anyone to accept my word on a topic. I hope that you try to look at this objectively and pour through Scripture seeking God's insight (the Holy Spirit, Scripture says, will lead us into ALL truth). God is a rewarder of those who diligently seek Him.
