46 Grk “exchanged the glory of the incorruptible God in likeness of an image of corruptible man.” Here there is a wordplay on the Greek terms ἄφθαρτος (aphthartos, “immortal, imperishable, incorruptible”) and φθαρτός (phthartos, “mortal, corruptible, subject to decay”).
47 Possibly an allusion to Ps 106:19–20.
