Now, since he consists of two parts, body and soul, the point to be inquired into is, in which of these two man would seem to have been lost? If in his body, then it is his body, not his soul, which is lost. What, however, is lost, the Son of man saves. The body, therefore, has the salvation. If, (on the other hand,) it is in his soul that man is lost, salvation is designed for the lost soul; and the body which is not lost is safe. If, (to take the only other supposition,) man is wholly lost, in both his natures, then it necessarily follows that salvation is appointed for the entire man; and then the opinion of the heretics is shivered to pieces, who say that there is no salvation of the flesh. And this affords a confirmation that Christ belongs to the Creator, who followed the Creator in promising the salvation of the whole man.
