Ambrose of Milan
Catena Aurea · Lukasevangelium 5
Now when he had left speaking, he said unto Simon, Launch out into the deep, and let down your nets for a draught. And Simon answering said unto him, Master, we have toiled all the night, and have taken nothing: nevertheless at thy word I will let down the net. And when they had this done, they inclosed a great multitude of fishes: and their net brake. And they beckoned unto their partners, which were in the other ship, that they should come and help them. And they came, and filled both the ships, so that they began to sink.
But the other ship is Judæa, out of which James and John are chosen. These then came from the synagogue to the ship of Peter in the Church, that they might fill both ships. For at the name of Jesus every knee shall bow, whether Jew or Greek.
