Clive Staples Lewis. The Screwtape Letters (№ 419244)

Let people consider the embellished version of what the Enemy promises only as a result of marriage as the basis of marriage. Two not bad possibilities follow from this at once. First, people who do not have the gift of abstinence can be deterred from marriage, because they are not “in love” - thanks to us, the idea of marriage “not for love” will seem low or cynical to them. Yes, yes, they think so. They believe that the intention to marry for mutual assistance, the protection of chastity and procreation is lower than an accidental storm of feelings. (Do not neglect the opportunity, make your patient consider the rite of marriage very imperfect.) Secondly, any sexual attraction that tends to marriage will be considered "love", and love of this kind will excuse any sin and, quite possibly, provoke marriage to a woman completely worldly, stupid or depraved.
