94 Paul certainly is dead, and by his honourable passion exchanged the life of the body for everlasting glory; did he then deceive himself when he wrote that he should be caught up alive in the clouds to meet Christ? We read the same too of Enoch and of Elijah, and thou too shall be caught up in the Spirit. Lo the chariot of Elijah, lo the fire, though not seen are prepared, that the just may ascend, the innocent be borne forth, and your life may not know death. For indeed the apostles knew not death, according to that which was said: “Verily, verily, I say unto you, many of those standing here shall not taste death until they see the Son of man coming in His kingdom.” For he lives, who has nothing in him which can die, who has not from Egypt any shoe or bond, but has put it off before laying aside the service of this body. And so not Enoch alone is alive, for not he alone was caught up; Paul also was caught up to meet Christ.
