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.
Rightly did He thus build the foundations of the brotherhood of the Church on love, that from such roots a copious sap of love might flow to the branches; and that too on natural or human love, that nature as well as grace might bind their love more firmly. They were moreover brothers; and so did God in the Old Testament lay the foundations of His building on Moses and Aaron, brothers. But as the grace of the New Testament is more abundant than that of the Old, therefore the first people were built upon one pair of brethren, but the new people upon two. They were washing their nets, a proof of the extremest indigence; they repaired the old because they had not whence they should buy new. And what shews their great filial piety, in this their great poverty they deserted not their father, but carried him with them in their vessel, not that he might aid in their labour, but have the enjoyment of his sons’ presence.
