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.
