In that same scene Moses also and Elias gave proof that the same condition of bodily existence may continue even in glory—the one in the likeness of a flesh which he had not yet recovered, the other in the reality of one which he had not yet put off.
…So likewise changes, conversions and reformations will necessarily take place to bring about the resurrection, but the substance of the flesh will still be preserved safe.
Tertullian
On the Resurrection of the Flesh
Chapter LV
