Pseudo-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.
The operations of their secular craft were a prophecy of their future dignity. As he who casts his net into the water knows not what fishes he shall take, so the teacher casts the net of the divine word upon the people, not knowing who among them will come to God. Those whom God shall stir abide in his doctrine.
