Augustine of Hippo
Catena Aurea · Lukasevangelium 5
And it came to pass, that, as the people pressed upon him to hear the word of God, he stood by the lake of Gennesaret, And saw two ships standing by the lake: but the fishermen were gone out of them, and were washing their nets. And he entered into one of the ships, which was Simon’s, and prayed him that he would thrust out a little from the land. And he sat down, and taught the people out of the ship.
(de Quæst. Ev. 1. 2. c. 2.) From which ship He taught the multitude, for by the authority of the Church He teaches the Gentiles. But the Lord entering the ship, and asking Peter to put off a little from the land, signifies that we must be moderate in our words to the multitude, that they may be neither taught earthly things, nor from earthly things rush into the depths of the sacraments. Or, the Gospel must first be preached to the neighbouring countries of the Gentiles, that (as He afterwards says, Launch out into the deep,) He might command it to be preached afterwards to the more distant nations.
