"Wherefore it behooves of these men which have companied with us all the time." Why does he make it their business too? That the matter might not become an object of strife, and they might not fall into contention about it. For if the Apostles themselves once did this, much more might those. This he ever avoids. Wherefore at the beginning he said, "Men and brethren. It behooves" to choose from among you. He defers the decision to the whole body, thereby both making the elected objects of reverence and himself keeping clear of all invidiousness with regard to the rest. For such occasions always give rise to great evils.
Now that some one must needs be appointed, he adduces the prophet as witness: but from among what persons: "Of these," he says, "which have companied with us, all the time that the Lord Jesus went in and out among us, beginning from the baptism of John unto that same day that He was taken up from us, must one be ordained to be a witness with us of His resurrection": that their college might not be left mutilated. Then why did it not rest with Peter to make the election himself: what was the motive? This; that he might not seem to bestow it of favor. And besides, he was not yet endowed with the spirit.
"Wherefore of these men which have companied with us," continues Peter. Observe how desirous he is they should be eye-witnesses. It is true indeed that the Spirit would shortly come; and yet great care is shown with regard to this circumstance. "Of these men," he says, "which have companied with us, all the time that the Lord Jesus went in and out among us." He shows that they had dwelt with Christ, not simply been present as disciples. In fact, from the very beginning there were many that then followed Him. "All the time," he says, "that the Lord Jesus went in and out among us, beginning from the baptism of John." True! for no one knew what preceded that event, though they did learn it by the Spirit. "Unto that same day that He was taken up from us, must one be ordained to be a witness with us of His resurrection." He said not, a witness of the rest of his actions, but a witness of the resurrection alone. For indeed that witness had a better right to be believed, who was able to declare, that He Who ate and drank, and was crucified, the same rose again. Wherefore it was needed that he should be a witness, not only of the time preceding this event, nor only of what followed it, and of the miracles; the thing required was, the resurrection. For the other matters were manifest and acknowledged, but the resurrection took place in secret, and was manifest to these only. And they do not say, Angels have told us; but, We have seen. For this it was that was most needful at that time: that they should be men having a right to be believed, because they had seen.
