There are also celestial bodies, and bodies terrestrial: but the glory of the celestial is one, and the glory of the terrestrial is another.
All Commentaries on 1 Corinthians 15:40 Go To 1 Corinthians 15
Augustine of Hippo
AD 430
If any man does not believe that common flesh can be changed into a nature of this sort, he is to be convinced toward faith by gradual steps. If you ask them whether earth can be changed into water, that will not seem to him incredible because there is no great distance between these two elements. Again if you ask whether water can be changed into air, he will agree that that is not absurd because these two elements are close neighbors.
