Paul is the real founder of Christianity:

The teachings of Jesus as the Son of God were not preached by Jesus nor accepted by Jesus, but were taught by Paul as supported in Acts 9:20:

"And straightway he preached Christ in the synagogues, that he is the Son of God."Did Jesus ever claim to be God or say, "Here am I, your God, worship me"?The answer is no.For there is no single, unequivocal statement in the Bible whereby Jesus himself declares, "I am God, therefore worship me."Virtually all of the more than two thousand verses of the epistles of Paul are his own fabrications to include Romans 9:5 that says, depending upon which Bible you read:

"...Christ came, who is overall, the eternally blessed God."

Christians should know that Paul himself mentions his own gospel, not Jesus, in his epistle to the Romans when he says in Romans 2:16:

"In the day when God will judge the secrets of men by Jesus Christ, according to my gospel."In face, the Pauline epistle to the Romans serves as the foundation of today's Christianity.Thus, it is the Christians whose efforts will be wastedin this life as they think they were acquiring good by their works when they attribute partners to God, as stated in Chapter 18:103-106 of the Qur'an:

"Say: Shall we tell you of those who lost most in respect of their deeds? Those whose efforts have been wasted in this life, while they thought that they were acquiring good by their works?"they are those who deny the Signs of their Lord and the fact of their having to meet Him (in the Hereafter): vain will be their works, nor shall We, on the Day of judgment, give them any weight.That is their reward, Hell;because they rejected Faith, and took My Signs and My Messengers by way of jest.(Al-Kahf 18:103-106)

Indeed, it is so strange and ironic, knowing that none of Paul's epistle to the Romans, more than 430 verses, were ever formulated by Jesus.Paul should have made direct reference to the pristine teachings of Jesus, if only the former claim for apostleship by divine inspiration was indeed true.Instead, large parts of his epistles' Biblical quotations (notably those in the Epistle to the Romans) were taken from the Old Testament - Genesis, Exodus, Leviticus, Deuteronomy, 2 Samuel, 1 Kings, Psalms,Proverbs, Isaiah, Ezekiel and Hosea.His epistles were, indeed a product of tedious efforts, but that does not make Paul far better than any of the other men who authored the Bible, nor does it make him a Prophet.

Other practices that were adopted under Paul included the following: the Roman sun-day as the Christian Sabbath;the traditional birthday of the Sun-god as the birthday of Jesus emblem of the sun-god (the cross of) to be the emblem of Christians;and, the incorporation of all the ceremonies which were performed at the Sun-god's birthday celebrations.

Paul was one of the real and fanatical enemies of Jesus Christ,he tutured and even became happy when Steven one of Jesus's followers was mercilessly killed .

Later Paul pretended to be one of them (Jesus's disciples) while he is not.All Jesus's disciples rejected him for pretending and hypocrisy.
There was misunderstanding between Paul and Peter regards inviting Gentiles (the Non-Jews) to Jesus's message.
Paul became a problem to all Jesus's disciples as well to the Christian world today.Read what Paul says in his hypocritacal pretence.
"I made myself slave to all,that I might win the more (converts by cuning). To the Jews I became as a Jew,in order to win Jews. To those under the law I became as one under the law though not being under the law that I might win those under the law. To those outside the law I became as one outside the law not being without law toward God but under the law of Christ(not under the law of God)".1Corinthians 9:19.
From the above statement of Paul,you understand that Paul tried to deceive those claim to be Christians today and he succeeded in cuning plan because Christians beleive in Paul over Jesus Christ.
Definitely,Paul is the real founder of Christianity.

* He was an unbeliever who did not believe in Christ in any way.
