Which is why paul himself brought paganism into christianity by introducing the worship of multiple gods
If you want to claim that Christian worship multiple gods because you don't accept our understanding of the Trinity as monotheistic but tritheistic, we'll just have to agree to disagree on that point. But, you are sadly mistaken if you think that Paul introduced this. Take a look at the record, Peter is the one who introduces this idea in his very first sermon at Pentecost:
"Therefore let all Israel be assured of this: God has made this Jesus, whom you crucified, both Lord and Christ" Acts 2:36. The phrase "Lord and Christ" is not just a couple of human titles that are being attributed to Jesus. The term "Christ" is a reference to Jesus being the Messiah. Not just an anointed instrument of God, but in this case being THE anointed and chosen one of God who is to bring about and accomplish the redemption of the nation of Israel and all nations spoken of by the prophets. And the term "Lord" is to use for Jesus is not just being polite like saying "sir"; in this context "Lord" is the word that Jews used as a substitute for YHWH, God's personal name. Peter is declaring that Jesus is none other than the very same being that Moses spoke to at the burning bush.
We see more of how Peter equated Jesus (who he calls "Lord" in vs. 36) with God a second time as he responds to questions posed to him about what all of this meant:
38Peter replied, "Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit.
39The promise is for you and your children and for all who are far off—for all whom
the Lord our God will call." Having just called Jesus "Lord" he now refers to "the Lord" as "our God".
So, accuse us of polytheism if you want. But get the source right. It isn't Paul and it isn't Greek paganism. It is Peter and Thomas ("My Lord and my God" John 20:28) and even the Didache that you asked about in another thread, for it too refers to Jesus as "the Lord", in praying to the Father refers to Jesus as "your child", and (in the epitome of what you would call polytheism) instructs people to be baptized "in the name of the Father and of the Son and of the Holy Spirit." All of this while Paul is still breathing threats against the followers of Jesus specifically for at the time thinking exactly what you continue to accuse Christians of NOT being true monotheists.
aadil, I know you are capable of thinking for yourself. So, quit allowing yourself to be spoonfed by those who simply want to attack Paul. You can for coming late to the party and in the end teaching things that you disagree with. But what you accuse him of here, bringing paganism into Christianity, he is guiltless.
He didn't bring Trinitarian ideas to Christianity, he found them already existing within it, first fought against them, second was converted to them, and then spread them to the world.
