Marcos 9
Glossa Ordinaria
Marcos 9:13
[(as quoted by Aquinas, AD 1274)] (non in Gloss. sed ap. Chrys ubi sup.) He calls John Elias, not because he was Elias in person, but because he fulfilled the ministry of Elias; for as the latter will be the forerunner of the second advent, so the former has been that of the first. — Catena Aurea by Aquinas
Marcos 9:22-23
[(as quoted by Aquinas, AD 1274)] (non occ.) Now he expresses in the words of his petition his want of faith; for that is the reason why he adds, But if thou canst do any thing, have compassion on us, and help us. For in that he says, If thou canst do any thing, he shows that he doubts His power, because he had seen that the disciples of Christ had failed in curing him; but he says, have compassion on us, to show the misery of the son, who suffered, and the father, who suffered with him. It goes on: Jesus said unto him, If thou canst believe, all things are possible to him that believeth. — Catena Aurea by Aquinas
Marcos 9:43
[(as quoted by Aquinas, AD 1274)] (non occ.) By maimed He means, deprived of the help of some friend, for it is better to enter into life without a friend, than to go with him into hell. — Catena Aurea by Aquinas
