Catena Aurea · Johannesevangelium 21
After these things Jesus shewed himself again to the disciples at the sea of Tiberias; and on this wise shewed he himself. There were together Simon Peter, and Thomas called Didymus, and Nathanael of Cana in Galilee, and the sons of Zebedee, and two other of his disciples. Simon Peter saith unto them, I go a fishing. They say unto him, We also go with thee. They went forth, and entered into a ship immediately; and that night they caught nothing. But when the morning was now come, Jesus stood on the shore: but the disciples knew not that it was Jesus. Then Jesus saith unto them, Children, have ye any meat? They answered him, No. And he said unto them, Cast the net on the right side of the ship, and ye shall find. They cast therefore, and now they were not able to draw it for the multitude of fishes. Therefore that disciple whom Jesus loved saith unto Peter, It is the Lord. Now when Simon Peter heard that it was the Lord, he girt his fisher’s coat unto him, (for he was naked,) and did cast himself into the sea. And the other disciples came in a little ship; (for they were not far from land, but as it were two hundred cubits,) dragging the net with fishes. As soon then as they were come to land, they saw a fire of coals there, and fish laid thereon, and bread. Jesus saith unto them, Bring of the fish which ye have now caught. Simon Peter went up, and drew the net to land full of great fishes, an hundred and fifty and three: and for all there were so many, yet was not the net broken.
(Tract. cxxii) It is not then signified that only a hundred and fifty-three saints are to rise again to eternal life, but this number represents all who partake of the grace of the Holy Spirit: which number too contains three fifties, and three over, with reference to the mystery of the Trinity. And the number fifty is made up of seven sevens, and one in addition, signifying that those sevens are one. That they were great fishes too, is not without meaning. For when our Lord says, I came not to destroy the law, but to fulfil, by giving, that is, the Holy Spirit through Whom the law can be fulfilled, He says almost immediately after, Whosoever shall do and teach them, the same shall be called great in the kingdom of heaven. In the first draught the net was broken, to signify schisms; but here to shew that in that perfect peace of the blessed there would be no schisms, the Evangelist continues: And for all they were so great1, yet was not the net broken; as if alluding to the case before, in which it was broken, and making a favourable comparison.
