Augustine of Hippo — as excerpted in the Catena Aurea on John 21:1-11

“(Tract. cxxii) The shore is the end of the sea, and therefore signifies the end of the world. The Church is here typified as she will be at the end of the world, just as other draughts of fishes typified her as she is now. Jesus before did not stand on the shore, but went into a ship which was Simon’s, and asked him to put out a little from the land. In a former draught the nets are not thrown to the right, or to the left, so that the good or the bad should be typified alone, but indifferently: Let down your nets for a draught, (Luke 5:4) meaning that the good and bad were mixed together. But here it is, Cast the net on the right side of the ship; to signify those who should stand on the right hand, the good. The one our Lord did at the beginning of His ministry, the other after His resurrection, shewing therein that the former draught of fishes signified the mixture of bad and good, which composes the Church at present; the latter the good alone, which it will contain in eternity, when the world is ended, and the resurrection of the dead completed. But they who belong to the resurrection of life, i. e. to the right hand, and are caught within the net of the Christian name, shall only appear on the shore, i. e. at the end of the world, after the resurrection: wherefore they were not able to draw the net into the ship, and unload the fishes, as they were before. The Church keeps these of the right hand, after death, in the sleep of peace, as it were in the deep, till the net come to shore. That the first draught was taken in two little ships, the last two hundred cubits from land, a hundred and a hundred, typifies, I think, the two classes of elect, circumcised and uncircumcised.”
