The opposition to contraception has, as I said, no scriptural basis. Pope Pius XI once said that it did, citing in his encyclical Casti Connubii (1930) the condemnation of Onan for “spilling his seed” rather than impregnating a woman (Genesis 38.9). But later popes had to back off from this claim, since everyone agrees now that Onan’s sin was not carrying out his duty to give his brother an heir (Deuteronomy 25.5-6). Then the “natural law” was fallen back on, saying that the natural purpose of sex is procreation, and any use of it for other purposes is “unnatural.” But a primary natural purpose does not of necessity exclude ancillary advantages. The purpose of eating is to sustain life, but that does not make all eating that is not necessary to subsistence “unnatural.” One can eat, beyond the bare minimum to exist, to express fellowship, as one can have sex, beyond the begetting of a child with each act, to express love…

Catholics who do not accept the phony argument over contraception are said to be “going against the teachings of their church.” That is nonsense. They are their church. The Second Vatican Council defines the church as “the people of God.” Thinking that the pope is the church is a relic of the days when a monarch was said to be his realm. The king was “Denmark.” Catholics have long realized that their own grasp of certain things, especially sex, has a validity that is lost on the celibate male hierarchy. This is particularly true where celibacy is concerned…

When Paul reaffirmed the ban on birth control in Humanae Vitae (1968) there was massive rejection of it. Some left the church. Some just ignored it. Paradoxically, the document formed to convey the idea that papal teaching is inerrant just convinced most people that it can be loony. The priest-sociologist Andrew Greeley said that Humanae Vitae did more damage to the papacy than any of the so-called “liberal” movements in Catholicism. When Pius IX condemned democracy and modern science in his Syllabus of Errors (1864), the Catholic historian Lord Acton said that Catholics were too sensible to go crazy every time a pope does. The reaction to Humanae Vitae proves that.
