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 by this the lofty merit of the three mentioned above is shewn, who merited to hear in the mountain the thunders of the Father, when he proclaimed in thunder through a cloud concerning the Son, This is my beloved Son; that they also through the cloud of the flesh and the fire of the word1, (Matt. 17:1) might as it were scatter the thunderbolts in rain on the earth, since the Lord turned the thunderbolts into rain, so that mercy extinguishes what judgment sets on fire. It goes on: And Andrew, who manfully does violence to perdition, so that he had ever ready within him his own death, to give as an answer, and his soul was ever in his hands. (1 Pet. 3:15. Ps. 119:109. Bede ubi sup.)
