78 John, again, although he tells us plainly that he has passed over many of the things which Jesus did, has been pleased, nevertheless, to give us a narrative of a third manifestation of Himself, which the Lord granted to the disciples after the resurrection, namely, by the sea of Tiberias, and before seven of the disciples—that is to say, Peter, Thomas, Nathanael, the sons of Zebedee, and two others who are not mentioned by name. That is the occasion when they were engaged in fishing; when, in obedience to His command, they cast the nets on the right side, and drew to land great fishes, a hundred and fifty and three: when He also asked Peter three times whether He was loved by him, and charged him to feed His sheep, and delivered a prophecy regarding what he would suffer, and said also, with reference to John, “Thus I will that he tarry till I come.” And with this John has brought his Gospel to its conclusion.
