True enough, through the insight of the prophets and particularly the experience of psalmists, this conception of the Apart-God became increasingly rich in the persuasion of His unfailing care for His children. None the less, the Hebrew God is a Transcendent God and Christianity inherits from that. Christianity took over what Judaism refused--Jesus Christ and His Gospel. But out of the immeasurable wealth of His teaching apostolic thinking naturally appropriated and made most of what was nearest in line with the prophets and the lawgivers of their race. Judaism refused Christ but the Twelve Apostles were Jews and the greatest of the group--St. Paul--was a Jewish Rabbi before he became a Christian teacher. He had been nurtured and matured in the schools of his people and though he was reborn, in renunciations and obediences distinctly Christian, there were in his very soul inherited rigidities of form in conformity to which he recast his faith.
More distinctly than he himself could ever have known, he particularized the Gospel of Jesus Christ. Doubtless his own experience was the deeper directing force in all this. Theologies always, to begin with, are the molten outpouring of some transforming experience and they are always, to begin with, fluid and glowing.
Such glowing experiences as these are hard to communicate; they, too, soon harden down and we inherit, as cold and rigid form, what was to begin with the flaming outcome of experience. St. Paul's own struggle and the bitterness of a divided self which issued in his conversion naturally gave content to all his after teaching. He worked out his system strangely apart from the other group of disciples; he had probably never heard a word of Christ's teaching directly from Christ's lips; he naturally fell back, therefore, upon his Jewish inheritance and widened that system of sacrifices and atonements until he found therein not only a place for the Cross but the necessity for it. He made much, therefore, of the sense of alienation from God, of sin and human helplessness, of the need and possibility of redemption.
