Peter against such a reception are also undoubted facts. Hitherto he shared the opinion common to all the Twelve that such a reception was contrary to the Divine law and purposes. He must have received upon the housetop some kind of a heavenly communication which he regarded as equivalent in authority to that ancient rule by which he esteemed the promises and mercy of God limited to the seed of Abraham. But as for any endeavour to understand or explain the mode of God's action on this occasion, it will be just as vain as attempts to pierce the mysteries of God's action in creation, the incarnation, or, to come lower still, in the processes by which life has been communicated to this world and is now sustained and continued thereon. We are in very deed living and moving amid mysteries, and if we refuse to learn or meditate till the mysteries we meet with, the very first step we take, be cleared, we must cease to think and be content to pass life like the beasts that perish. We know not, indeed, the exact manner in which God communicated with St. Peter, or for that matter with any one else to whom He made revelation of His will. We know nothing of the manner in which He spoke to Moses out of the bush, or to Samuel in the night season, or to Isaiah in the Temple. As with these His servants of the Elder Dispensation, so it was with St. Peter on the housetop. We know, however, how St. Luke received his information as to the nature of the vision and all the other facts of the case. St. Luke and St. Peter must have had many an opportunity for conversation in the thrilling, all-important events amid which he had lived. St. Luke too accompanied St. Paul on that journey to Jerusalem described in the twenty-first chapter, and was introduced to the Christian Sanhedrin or Council over which St. James the Just presided. But even if St. Luke had never seen St. Peter, he had abundant opportunities of learning all about the vision. St. Peter proclaimed it to the world from the very time it happened, and was obliged to proclaim it as his defence against the party zealous for the law of Moses. St. Peter referred to what God had just shown him as soon as he came into the centurion's presence. He described the vision at full length as soon as he came to Jerusalem and met the assembled Church, where its power and meaning were so clearly recognised that the mouths of all St. Peter's adversaries were at once stopped. And again at the Council of Jerusalem held, as described in the fifteenth chapter, St. Peter refers to the circumstances of this whole story as well known to the whole Church in that city. St. Luke then would have no difficulty, writing some twenty years later, in ascertaining the facts of this story, and naturally enough, when writing to a Gentile convert and having in mind the needs and feelings of the Gentiles, he inserted the narrative of the vision as being the foundation-stone on which the growing and enlarging
