St. Paul at his first appearance upon the stage of Christian history, upon the occasion of St. Stephen's martyrdom, had arrived at the full stature of manhood both in body and in mind. He was then the young man Saul; an expression which enables us to fix with some approach to accuracy the time of his birth. St. Paul's contemporary Philo in one of his works divides man's life into seven periods, the fourth of which is young manhood, which he assigns to the years between twenty-one and twenty-eight. Roughly speaking, and without attempting any fine-drawn distinctions for which we have not sufficient material, we may say that at the martyrdom of St. Stephen St. Paul was about thirty years of age, or some ten years or thereabouts junior to our Lord as His years would have been numbered according to those of the sons of men. One circumstance, indeed, would seem to indicate that St. Paul must have been then over and above the exact line of thirty. It is urged, and that upon the ground of St. Paul's own language, that he was a member of the Sanhedrin. In the twenty-sixth chapter, defending himself before King Agrippa, St. Paul described his own course of action prior to his conversion as one of bitterest hostility to the Christian cause: "I both shut up many of the saints in prisons, having received authority from the chief priests, _and when they were put to death, I gave my vote against them_"; an expression which clearly indicates that he was a member of a body and possessed a vote in an assembly which determined questions of life and death, and that could have been nothing else than the Sanhedrin, into which no one was admitted before he had completed thirty years. St. Paul, then, when he is first introduced to our notice, comes before us as a full-grown man and a well-trained, carefully educated, thoroughly disciplined rabbinical scholar, whose prejudices were naturally excited against the new Galilean sect, and who had given public expression to his feelings by taking decided steps in opposition to its progress. The sacred narrative now sets before us (i) the Conduct of St. Paul in his unconverted state, (ii) his Mission, (iii) his Journey, and (iv) his Conversion. Let us take the many details and circumstances connected with this passage under these four divisions.
