Before getting married three years ago, my wife and I attended Catholic pre-Cana class. The teacher eventually faced the unenviable but entirely predictable task of explaining to half a room of lapsed Catholics, brought up in a modern culture that finds Ke$ha’s existence not only entirely acceptable but also worth broadcasting over countless radio stations, why the Church has such antiquated beliefs on sexuality and birth control. After some intro on Humanae Vitae and Pope John Paul II’s Theology of the Body, the teacher unleashed this simple yet profound rhetorical, “You ever notice how you only disagree with Church teaching when it conflicts with something you want to do?” Well, duh, but… hmmm.
