Pseudo-Jerome
Catena Aurea · Markusevangelium 3
And he goeth up into a mountain, and calleth unto him whom he would: and they came unto him. And he ordained twelve, that they should be with him, and that he might send them forth to preach, And to have power to heal sicknesses, and to cast out devils: And Simon he surnamed Peter; And James the son of Zebedee, and John the brother of James; and he surnamed them Boanerges, which is, The sons of thunder: And Andrew, and Philip, and Bartholomew, and Matthew, and Thomas, and James the son of Alphæus, and Thaddæus, and Simon the Canaanite, And Judas Iscariot, which also betrayed him.
Or spiritually, Christ is the mount, from which living waters flow, and milk is procured for the health of infants; whence the spiritual feast of fat things is made known, and whatsoever is believed to be most highly good is established by the grace of that Mountain. Those therefore who are highly exalted in merits and in words are called up into a mountain, that the place may correspond to the loftiness of their merits. It goes on: And they came unto him, &c. For the Lord loved the beauty of Jacob, (Ps. 46 Vulg.) that they might sit upon twelve thrones, judging the twelve tribes of Israel, (Matt. 19:28) who also in bands of threes and fours watch around the tabernacle of the Lord, and carry the holy words of the Lord, bearing them forward on their actions, as men do burdens on their shoulders.
