After that, Pentecost is a most joyous space for conferring baptisms; wherein, too, the resurrection of the Lord was repeatedly proved among the disciples, and the hope of the advent of the Lord indirectly pointed to, in that, at that time, when He had been received back into the heavens, the angels told the apostles that "He would so come, as He had withal ascended into the heavens; " at Pentecost, of course.
The Passover affords a more than usually solemn day for baptism; when, withal, the Lord's passion, in which we are baptized, was completed. Nor will it be incongruous to interpret figuratively the fact that, when the Lord was about to celebrate the last Passover, He said to the disciples who were sent to make preparation, "You will meet a man bearing water." He points out the place for celebrating the Passover by the sign of water. After that, Pentecost is a most joyous space for conferring baptisms; wherein, too, the resurrection of the Lord was repeatedly proved among the disciples [Acts 1:3], and the hope of the advent of the Lord indirectly pointed to, in that, at that time, when He had been received back into the heavens [Acts 1:9], the angels told the apostles that "He would so come, as He had withal ascended into the heavens;" [Acts 1:11] at Pentecost, of course. But, moreover, when Jeremiah says, "And I will gather them together from the extremities of the land in the feast-day," he signifies the day of the Passover and of Pentecost, which is properly a "feast-day." However, every day is the Lord's; every hour, every time, is apt for baptism: if there is a difference in the solemnity, distinction there is none in the grace.
"And while they looked stedfastly," it is said, "toward heaven, as he went up, behold, two men stood by them in white apparel; which also said, Ye men of Galilee, why stand ye gazing up into heaven? This same Jesus, which is taken up from you into heaven" - they used the expression "This" demonstratively, saying, "this Jesus, which is taken up from you into heaven, shall thus" - demonstratively, "in this way" - "come in like manner as ye have seen Him going into heaven." Again, the outward appearance is cheering - "in white apparel." They were Angels, in the form of men. And they say, "Ye men of Galilee:" they showed themselves to be trusted by the disciples, by saying, "Ye men of Galilee." For this was the meaning: else, what needed they to be told of their country, who knew it well enough? By their appearance also they attracted their regard, and showed that they were from heaven.
"Behold, two men stood by them." That they may vent no sorrowful exclamations, and that it might not be with them as it was with Elisha, who, when his master was taken up, rent his mantle (2 Kings ii. 12). And what say they? "This Jesus, which is taken up from you into heaven, shall thus come." And, "Behold, two men stood by them." With good reason: for "in the mouth of two witnesses shall every word be established" (Deut. xvii. 6): and these utter the same things. And it is said, that they were "in white apparel." In the same manner as they had already seen an Angel at the sepulchre, who had even told them their own thoughts; so here also an Angel is the preacher of His Ascension; although indeed the Prophets had frequently foretold it, as well as the Resurrection.
Behold, two men stood by them in white apparel. White garments are more fitting for exaltation than for humiliation. And so, as the Lord ascends, angels appear in white garments, who are not said to appear in white clothing at the Lord's birth, because he who appeared humble as a God in his birth, appeared sublime as a man in his ascension. For the location is also fitting, while he, who was born as a man in a humble little city, returned to heaven from a high mountain.
While they were looking on as he went into heaven. In Greek, it is thus: And while they were gazing into heaven as he went; that is, they were gazing into heaven, where he was going. Hence, the angels say to them: Why do you stand looking into heaven? Because it is also shown that they were gazing at him who was going into heaven, by the angels' following words, when it is said: He will come in the same way you saw him going into heaven.
