John Chrysostom
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.
He calls them while actually working at their employment, to shew that to follow Him ought to be preferred to all occupations. They were just then casting a net into the sea, which agreed with their future office.
