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.
(ap. Anselm.) These last disciples were an example to such as leave their property for the love of Christ; now follows an example of others who postponed earthly affection to God. Observe how He calls them two and two, as He afterwards sent them two and two to preach.
