At this point undoubtedly he had precursors. The significance of the Cross of Christ was by no means entirely unknown to those who had been disciples before him; he himself places the assertion that Christ "died for our sins according to the Scriptures" as one of the things that he had "received." But unless all indications fail Paul did bring an unparalleled enrichment of the understanding of the Cross. For the first time the death of Christ was viewed in its full historical and logical relationships. And thereby Gentile freedom, and the freedom of the entire Christian Church for all time, was assured. Inwardly, indeed, the early Jerusalem disciples were already free from the Law; they were really trusting for their salvation not to their observance of the Law but to what Christ had done for them. But apparently they did not fully know that they were free; or rather they did not know exactly why they were free. The case of Cornelius, according to the Book of Acts, was exceptional; Cornelius had been received into the Church without being circumcised, but only by direct command of the Spirit. Similar direct and unexplained guidance was apparently to be waited for if the case was to be repeated. Even Stephen had not really advocated the immediate abolition of the Temple or the abandonment of Jewish prerogatives in the presence of Gentiles. The freedom of the early Jerusalem Church, in other words, was not fully grounded in a comprehensive view of the meaning of Jesus' work. Such freedom could not be permanent. It was open to argumentative attacks, and as a matter of fact such attacks were not long absent. The very life of the Gentile mission at Antioch was threatened by the Judaizers who came down from Jerusalem and said, "Except ye be circumcised after the manner of Moses, ye cannot be saved." Practical considerations, considerations of church polity, were quite powerless before such attacks; freedom was held by but a precarious tenure until its underlying principles were established. Christianity, in other words, could not live without theology. And the first great Christian theologian was Paul. It was Paul, then, who established the principles of the Gentile mission. Others labored in detail, but it was he who was at the heart of the movement. It was he, far more than any other one man, who carried the gospel out from Judaism into the Gentile world.
