“Scripture condemns the act (Gen. 38:8-10), as did all Christian denominations before 1930. At that time the Anglican Church decided to allow contraception in some circumstances. They soon gave in on the issue altogether, and before long virtually all Protestant denominations followed suit. Yet the Catholic Church stands fast on the teaching of historic Christianity. But why? Why doesn’t the Church “get with the times”?
The modern world has trouble understanding the Church’s stance on contraception because the world does not know the purpose of sex. The writer Frank Sheed said that “modern man practically never thinks about sex.” He dreams of it, craves it, pictures it, drools over it, but never pauses to actually think about it. Sheed continued: “Our typical modern man, when he gives his mind to it at all, thinks of sex as something we are lucky enough to have; and he sees all its problems rolled into the one problem of how to get the most pleasure out of it.”
But we should put more thought into the matter. Who invented sex? What is sex? What is its purpose? What is it worth? For starters, God invented sex. Since he is its author, he has the authority to determine its purpose and meaning. God has revealed that the purposes of sex are procreation and union (babies and bonding), and that the sexual act can be thought of as the wedding vows and promises made flesh. On a couple’s wedding day, they promise that their love will be free, faithful, total, and open to life. Each act of marital intercourse should be a renewal of these vows.
Some couples say that they will be open to life but will contracept between kids. In other words, they will be completely open to life—except when they sterilize their acts of love. Imagine if they had the same mentality with other parts of the wedding vows.”
