Augustine of Hippo
Catena Aurea · Matthäusevangelium 4
And Jesus, walking by the sea of Galilee, saw two brethren, Simon called Peter, and Andrew his brother, casting a net into the sea: for they were fishers. And He saith unto them, Follow Me, and I will make you fishers of men. And they straightway left their nets, and followed Him. And going on from thence, he saw other two brethren, James the son of Zebedee, and John his brother, in a ship with Zebedee their father, mending their nets; and He called them. And they immediately left the ship and their father, and followed Him.
(Aug. Tract. in Joann. vii. 17.) Had one learned been chosen, he might have attributed the choice to the merit of his learning. But our Lord Jesus Christ, willing to bow the necks of the proud, sought not to gain fishermen by orators, but gained an Emperor by a fisherman. Great was Cyprian the pleader, but Peter the fisherman was before him.
