The resurrection of the flesh.
But we must not doubt that this mortal flesh will rise again at the end of the world. For it is necessary that this corruptible must put on incorruption, and this mortal must put on immortality. It is sown in corruption, it will rise in incorruption; it is sown in dishonor, it will rise in glory: it is sown a natural body, it will rise a spiritual body. This is the Christian, this is the Catholic, this is the Apostolic faith. Believe Christ saying: Not a hair of your head will perish, and with unbelief cast out, rather consider how valuable you are. For what of ours can be despised by our Redeemer, whose hair cannot be despised? Or how shall we doubt that He will give eternal life to our soul and flesh, who for us took the soul and flesh in which He would die, and laid it down when He died, and took it up again so that death would not be feared? All that is delivered in the Creed, I have explained to your Charity according to the measure of my ministry. It is called the Creed for this reason, because the accepted faith of our fellowship is contained therein, and by its confession, as if by a given sign, the faithful Christian is recognized.
