For the record, the priest who married my wife and me in 1967 advised us that we could in good faith practice birth control. He reasoned that as Pope Paul VI was then preparing an encyclical regarding faith and sexuality, young Catholics could reasonably assume that church dogma regarding contraception would soon change to reflect contemporary realities: specifically that a couple intending to bring children into their marriage might legitimately seek to do so in their own time.
A university chaplain, he no doubt understood how the combination of Rome’s authoritarianism and theological nit-picking tended to drive educated young people from the church. Anyway, everybody knows how that worked out. Next came Humanae Vitae, Pope Paul VI’s 1968 doubling down on the church’s blanket condemnation of artificial means of birth control—a blast from the medieval past as most American Catholics now see it.
