The risen bodies are not transformed into spirit, but subjected to the perfect control of the spirit that animates them. Whereas in mortal man the soul can go only as far as the body will go, in the resurrection the body will go as far as the soul will go, to the utmost limits of its spiritual and quasi-angelic capacity. The soul (of the just) will then be delivered from the body of this death (Rom. vii, 24), inasmuch as the body will no longer hold it back and bring it down.
