That is the apparent point of Christ's metaphor that in the end God will separate "the wheat from the chaff" (Matthew 3:12; Luke 3:17) and burn the chaff away while keeping the wheat for himself, hence alluding to the firey apocalypse (see my discussions: p. 136, with n. 160, p. 211; and pp. 143, 150), where the "outer body" (the chaff) will be burned away and the "inner body" (the wheat), a body which only the saved have, will be freed and raised to new life. To make the same point, Origen used the analogy of casting off the placenta (see my discussion on pp. 143-44), just as Paul used the analogies of moving from one house to another and removing one coat and donning another (2 Cor. 5:1-8, with my discussion on pp. 137-40, esp. with nn. 180 and 181, pp. 212-13).
