Tactique du diable : Lettres d'un vétéran de la tentation à un novice

Now comes the joke. The Enemy [God] described a married couple as "one flesh". He did not lay "a happily married couple" or "a couple who married because they were in love", but you can make the humans ignore that. You can also make them forget that the man they call Paul did not confine it to married couples. Mere copulation, for him, makes "one flesh". You can thus get the humans to accept as rhetorical eulogies of "being in love" what were in fact plain descriptions of the real significance of sexual intercourse. The truth is that wherever a man lies with a woman, there, whether they like it or not, a transcendental relation is set up between them which must be eternally enjoyed or eternally endured.

From the true statement that this transcendental relation was intended to produce, and, if obediently entered into, too often will produce, affection and the family, humans can be made to infer the false belief that the blend of affection, fear, and desire which they call "being in love" is the only thing that makes marriage either happy or holy. The error is easy to produce because "being in love" does very often, in Western Europe, precede marriages which are made in obedience to the Enemy's designs, that is, with the intention of fidelity, fertility and good will; just as religious emotion very often, but not always, attends conversion. In other words, the humans are to be encouraged to regard as the basis for marriage a highly-coloured and distorted version of something the Enemy really promises as its result.

Two advantages follow. In the first place, humans who have not the gift of continence can be deterred from seeking marriage as a solution because they do not find themselves "in love", and, thanks to us, the idea of marrying with any other motive seems to them low and cynical. Yes, they think that. They regard the intention of loyalty to a partnership for mutual help, for the preservation of chastity, and for the transmission of life, as something lower than a storm of emotion. (Don't neglect to make your man think the marriage-service very offensive.) In the second place any sexual infatuation whatever, so long as it intends marriage, will be regarded as "love", and "love" will be held to excuse a man from all the guilt, and to protect him from all the consequences, if marrying a heathen, a fool, or a wanton.
