One of the most convincing proofs of the truth of the New Testament is the identity of character we behold in the representations given of St. Peter by writers who produced their books quite independently of each other. St. Paul wrote his Epistle to the Galatians long prior to any of the Gospel narratives. Yet St. Paul's picture of St. Peter in the Epistle to the Galatians is exactly the same as that drawn by the four Evangelists alike. St. Paul depicts him as the same intensely sympathetic, and therefore the same unstable person whom the Evangelists describe. The brave scene in the upper chamber, and the scene of cowardice and disgrace in the high priest's palace, were in principle re-enacted twenty years after, about the year A.D. 53, at Antioch. St. Peter was very bold in maintaining the right of Gentile freedom, and hesitated not to live like the Gentile Christians of Antioch, so long as none of the strict Jewish Christians of Jerusalem knew about it. St. Peter wished, in fact, to stand well with both parties, and therefore strove to conciliate both. He was, for the time, a type of that famous character Mr. Facing-two-ways. He lived, therefore, as a Gentile, until some of the Jerusalem brethren arrived at Antioch, when he at once quailed before them and retreated, betraying the cause of Christian freedom, and sacrificing, just as men do still, Christian principle and honesty upon the altar of self-seeking popularity. St. Peter, we therefore maintain, always remained at heart the same character. He was bold and forward for Christ so long as all went well, because he was intensely sympathetic; but he had very little of that power of standing alone which marked St. Paul, and nerved him, even though a solitary witness, when the cause of truth was involved. This somewhat lengthened argument is absolutely necessary to show the strength of our conclusion: that it must have been an overpowering sense of the awful reality of Christ's resurrection and ascension which alone could have overcome this natural weakness of St. Peter, and make him on the day of Pentecost as brave in proclaiming Jesus Christ to his red-handed murderers as he was bold to propose a new Apostle in place of the hapless traitor to the assembled disciples in the upper chamber. St. Peter evidently believed, and believed with an intense, overwhelming, resistless conviction, in the truth of Christ's resurrection and ascension, which thus became to him the source of personal courage and of individual power.
III. Again, the tone of St. Peter's sermon was remarkable because of its enlarged and enlightened spirituality. It proved the Spirit's power in illuminating the human consciousness. St. Peter was rapidly gaining a true conception of the nature of the kingdom of God. He enunciates that conception in this sermon. He proclaims Christianity, in its catholic and universal aspect, when he quotes the prophet Joel as predicting the time when the Lord would pour out His Spirit upon all flesh. St. Peter does not indeed seem to have realized all at once the full significance of his own teaching. He did not see that his words applied to the Gentiles equally with the Jews, sounding the death-knell of all national exclusiveness in religion. Had he seen the full meaning of his own words, he would not have hesitated so much about the baptism of Cornelius and the admission of the Gentiles. It has been found true, not only of St. Peter, but of teachers, reformers, politicians, statesmen, that they have not at once recognised all the vast issues and undeveloped principles which lay wrapped up in their original message. The stress and trial of life alone draw them out, at times compelling their authors to regret their earlier actions, at other times leading them to follow out with intensified vigour the principles and movements which they had themselves set in operation. Luther, when he protested against indulgences; Erasmus, when he ridiculed the ignorance of the monks and advocated the study of the Greek New Testament; John Hampden, when he refused to pay ship money; or Bishop Ken, when he declined obedience to the orders of King James II.;--none of them saw whereunto their principles would necessarily grow till time had thoroughly threshed their teaching and their actions, separating the husk of external circumstances, which are so variable, from the kernel of principle, which is eternally the same, stern, severe, inexorable, in its operations. So it was with St. Peter, and still earlier with the prophets. They sang of and preached a universal religion, as in this passage, but yet none of them realized the full scope and meaning of the words they had used, till a special revelation upon the housetop at Joppa compelled St. Peter to grasp and understand and apply the principles he had been already proclaiming.
