Thus the imposing construction of Baur was erected by neglecting all sources except Galatians and Corinthians, and then by misinterpreting these. When all the available sources are used, and estimated at their true value, the hypothesis of a fundamental conflict between Paul and the original apostles disappears. There was indeed a bitter conflict in the apostolic age, but, as Ritschl observed against Baur, it was a conflict not between Paul and the original apostles, but between all the apostles, including both Paul and Peter, on the one side, and an extreme Judaizing party on the other. The extreme Judaizing party, not having the support of the original disciples of Jesus, soon ceased to be influential. The various sects of schismatic Jewish Christians which appear in the second century--"Ebionites" and the like--if they had any roots at all the apostolic age (which is more than doubtful), could trace their spiritual descent not from the original apostles, but from the Judaizers. It is no wonder then that they were left behind in the march of the Church. They were left behind not because Peter was left behind--for Peter appears as at least one of the foundations upon which the Old Catholic Church was built--but because Peter had left them behind, or rather because Peter had never given them his support at all. They were left behind because from the beginning their spiritual ancestors in the apostolic age had not really belonged with apostolic Christianity, but had been "false brethren privily brought in." One fact, indeed, still requires explanation. If Paul and the original apostles were in such perfect agreement, how is it that the Judaizers in the apostolic age could appeal to the original apostles against Paul? The existence of that appeal cannot altogether be denied. The exact nature of the appeal is not indeed altogether clear. It is by no means clear that the Judaizers appealed to the original apostles in support of the content of the Judaizing message; it is by no means clear that they made Peter or James teach the necessity of the Mosaic Law for salvation. What is clear is only that they appealed to the original apostles in their personal attack against Paul; they contrasted Paul, who had become a disciple only after the crucifixion, with those who had been intimate with Jesus. They used Peter to discredit the apostolic authority of Paul, but it is not so clear that they used Peter to discredit the content of Paul's message.
