Whether it be possible to identify those "of Apollos" at Corinth with the beginnings of that Hellenistic perversion of the Pauline gospel into a mystical theosophy which afterwards passed into Gnosticism may be left an open question. At least we have come to see that the conditions of the church's growth were far more complex than Baur imagined. In particular it is necessary to distinguish four different attitudes on the single question of the obligation of the Law. There were (1) Judaizers who insisted on complete submission to the Law as the condition of salvation, for both Jews and Gentiles; (2) imitators of Cephas, who considered believers of Jewish birth to be "under the Law," but asked of Gentiles only such consideration for it as the special conditions seemed to require; (3) Paulinists, who held that neither Jews nor Gentiles are under the law, yet felt that consideration should be shown for the scrupulous when asked not as of right, but as of charity; (4) radicals, who recognized no limits to their freedom save the one new commandment. But while conflict first broke out over the mere concrete question of Gentile liberty, the real distinction of Paul's gospel from that of the older apostles was far deeper. The question as Tübingen critics conceived it concerned primarily the _extent_ of the gospel message,--to how large a circle was it offered? Modern criticism has come to see that the difference was in higher degree a difference of _quality_. Paul's whole message of redemption through the cross and resurrection started from other premises than those of the Galilean apostles, and was conceived in other terms. For this reason it leads over to a new Christology. In short, the transition of Christianity from its Jewish to its Gentile form is not a mere enlargement of its field by the abolition of particularistic barriers. The background we must study for the understanding of it is not so much mere contemporary history as the contemporary history _of religion_. The development from the Petrine gospel broadly characteristic of the Synoptic writings, through the Pauline Epistles to that of the Johannine writings, is a transition from Hebrew to Hellenistic conceptions of what redemption is, and how it is effected. Modern criticism expresses the contrast in its distinction of the gospel _of_ Jesus from the gospel _about_ Jesus.
