Catholicism has more claims to Christianity than Protestantism since Jesus gave the 'keys of the kingdom' to Peter, not to Paul. Paul Changed the course of Christianity and created a new religion which was far from what Jesus taught. Christians should at least be aware of what they are believing and living by. It is the religion of the Church and Paul,
not the religion of Jesus.
“That the figure of the Nazarene, as delivered to us in Mark’s Gospel, is decisively different from the pre-existent risen Christ proclaimed by Paul, is something long recognized by thinkers like Kant, Fichte, Schelling, Herder and Goethe, to mention only a few. The distinction between ‘the religion of Christ’ and ‘the Christian religion’ goes back to Lessing. Critical theological research has now disputed the idea of an uninterrupted chain of historical succession: Luther’s belief that at all times a small handful of true Christians preserved the true apostolic faith. Walter Bauer (226) and Martin Werner (227) have brought evidence that there was conflict from the outset about the central questions of dogma. It has become clear that the beliefs of those who had seen and heard Jesus in the flesh --- the disciples and the original community--- were at odds to an extraordinary degree with the teaching of Paul, who claimed to have been not only called by a vision but instructed by the heavenly Christ. The conflict at Antioch between the apostles Peter and Paul, far more embittered as research has shown (228) than the Bible allows us to see, was the most fateful split in Christianity, which in the Acts of the Apostles was ‘theologically camouflaged’. (229)
Paul, who had never seen Jesus, showed great reserve towards the Palestinian traditions regarding Jesus’ life. (230)
The historical Jesus and his earthly life are without significance for Paul. In all his epistles the name ‘Jesus’ occurs only 15 times, the title ‘Christ’ 378 times. In Jesus’s actual teaching he shows extraordinarily little interest. It is disputed whether in all his epistles he makes two, three or four references to sayings by Jesus. (231) It is not Jesus’ teaching, which he cannot himself have heard at all (short of hearing it in a vision), that is central to his own mission, but the person of the Redeemer and His death on the Cross.
Jesus, who never claimed religious worship for himself was not worshipped in the original community, is for Paul the pre-existent risen Christ….
This was the ‘Fall’ of Christianity: that Paul with his ‘Gospel’, which became the core of Christian dogma formation, conquered the world, (237) while the historic basis of Christianity was declared a heresy….
Pauline heresy served as the basis for Christian orthodoxy, and the legitimate Church was outlawed as heretical’. (240) The ‘small handful of true Christians’ was Nazarene Christianity, which was already extinct in the fourth century……
The centerpiece then, of Christian creedal doctrine, that of Redemption, is something of which—in the judgment of the theologian E. Grimm (244) --- Jesus himself knew nothing; and it goes back to Paul. “
