"if while we speak to him of this great mystery of generation, we join to the idea of the pleasure which the Author of nature has given to this act the idea of the exclusive affection which makes it delightful, the idea of the duties of faithfulness and modesty which surround it, and redouble its charm while fulfilling its purpose; if we paint to him marriage, not only as the sweetest form of society, but also as the most sacred and inviolable of contracts, if we tell him plainly all the reasons which lead men to respect this sacred bond, and to pour hatred and curses upon him who dares to dishonour it; if we give him a true and terrible picture of the horrors of debauch, of its stupid brutality, of the downward road by which a first act of misconduct leads from bad to worse, and at last drags the sinner to his ruin; if, I say, we give him proofs that on a desire for chastity depends health, strength, courage, virtue, love itself, and all that is truly good for man—I maintain that this chastity will be so dear and so desirable in his eyes, that his mind will be ready to receive our teaching as to the way to preserve it; for so long as we are chaste we respect chastity; it is only when we have lost this virtue that we scorn it."
