The historical criticism of the present century has brought this writing once more to the front of the conflict of faith. Born in controversy, it seems inevitably to be born for controversy. Its interpretation forms the pivot of the most thoroughgoing recent discussions touching the beginnings of Christian history and the authenticity of the New Testament record. The Galatian Epistle is, in fact, the key of New Testament Apologetics. Round it the Roman and Corinthian Letters group themselves, forming together a solid, impregnable quaternion, and supplying a fixed starting-point and an indubitable test for the examination of the critical questions belonging to the Apostolic age. Whatever else may be disputed, it is agreed that there was an apostle Paul, who wrote these four Epistles to certain Christian societies gathered out of heathenism, communities numerous, widely scattered, and containing men of advanced intelligence; and this within thirty years of the death of Jesus Christ. Every critic must reckon with this fact. The most sceptical criticism makes a respectful pause before our Epistle. Hopeless of destroying its testimony, Rationalism treats it with an even exaggerated deference; and seeks to extract evidence from it against its companion witnesses amongst the New Testament writings. This attempt, however misdirected, is a signal tribute to the importance of the document, and to the force with which the personality of the writer and the conditions of the time have stamped themselves upon it. The deductions of the Baurian criticism appear to us to rest on a narrow and arbitrary examination of isolated passages; they spring from a mistaken _à priori_ view of the historical situation. Granting however to these inferences, which will meet us as we proceed, their utmost weight, they still leave the testimony of Paul to the supernatural character of Christianity substantially intact. Of the four major Epistles, this one is superlatively characteristic of its author. It is _Paulinissima Paulinarum_--most Pauline of Pauline things. It is largely autobiographical; hence its peculiar value. Reading it, we watch history in the making. We trace the rise of the new religion in the typical man of the epoch. The master-builder of the Apostolic Church stands before us, at the crisis of his work. He lets us look into his heart, and learn the secret of his power. We come to know the Apostle Paul as we know scarcely any other of the world's great minds. We find in him a man of the highest intellectual and spiritual powers, equally great in passion and in action, as a thinker and a leader of men. But at every step of our acquaintance the Apostle points us beyond himself; he says, "It is not I: it is Christ that lives in me." If this Epistle teaches us the greatness of Paul, it teaches us all the more the Divine greatness of Jesus Christ, before whom that kingly intellect and passionate heart bowed in absolute devotion.
