Yes, technically you’re right people, the official pope was Silvestris I, I’m sorry about that

. But because Constantine had quite an impact on the fate of our Church, and took some major descisions, he’s sometimes being refered to as “pope”. I’ve been ‘googling’ around a bit on the Internet (in which I’m not that good btw.) and I found an example of this mistake:
reformation.org/pope-constantine.html
As for the Trinity, I was merely refering to the Councel of Nicea’s creed “We believe…in one Lord Jesus Christ, the Son of God, begotten from the Father, only-begotten, that is, from the substance of the Father, God from God, light from light, true God from true God, begotten, not made, of one substance with the Father, through Whom all things were made…” But indeed, it was established well before that, as you rightfully said. Just ignore those posts of mine. I was a bit too quick, sorry guys!
As for what I said about Jehowah’s Witnesses, IMHO, I don’t think I was wrong there.
