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.
But Simon is interpreted, ‘laying aside sorrow;’ for blessed are they that mourn, for they shall be comforted. (Matt. 5:4) And he is called Canaanite, that is, Zealot, because the zeal of the Lord ate him up. But Judas Iscariot is one who does not do away his sins by repentance. For Judas means ‘boaster,’ or vain-glorious. And Iscariot, ‘the memory of death.’ But many are the proud and vain-glorious confessors in the Church, as Simon Magus, and Arius, and other heretics, whose deathlike memory is celebrated in the Church, that it may be avoided.
