6 Paul proclaims in a loud and lofty voice, “But God forbid that I should glory, save in the cross of our Lord Jesus Christ, by whom the world is crucified unto me, and I unto the world.” And yet a virgin in the Church glories concerning her fleshly appearance and the beauty of her body! Paul adds, and says, “For they that are Christ's have crucified their flesh, with its faults and lusts.” And she who professes to have renounced the lusts and vices of the flesh, is found in the midst of those very things which she has renounced!
Virgin, you are taken, you are exposed, you boast one thing and affect another. You sprinkle yourself with the stains of carnal concupiscence, although you are a candidate of purity and modesty. “Cry,” says the Lord to Isaiah, “All flesh is grass, and all the glory of it as the flower of the grass: the grass withers, and the flower fades; but the word of the Lord endures for ever.” It is becoming for no Christian, and especially it is not becoming for a virgin, to regard any glory and honour of the flesh, but only to desire the word of God, to embrace benefits which shall endure for ever.
Or, if she must glory in the flesh, then assuredly let her glory when she is tortured in confession of the name; when a woman is found to be stronger than the tortures; when she suffers fire, or the cross, or the sword, or the wild beasts, that she may be crowned. These are the precious jewels of the flesh, these are the better ornaments of the body.
