Pope Benedict Xvi said this quote
“ The intellectual climate of the 1970s, for which the 1950s had already paved the way, contributed to this. A theory was even finally developed at that time that pedophilia should be viewed as something positive. Above all, however, the thesis was advocated-and this even infiltrated Catholic moral theology-that there was no such thing as something that is bad in itself. There were only things that were relatively bad. What was good or bad depended on the consequences. In such a context, where everything is relative and nothing intrinsically evil exists, but only relative good and relative evil, people who have an inclination to such behavior are left without no solid footing. Of course pedophilia is first rather a sickness of individuals, but the fact that it could become so active and so widespread was linked also to an intellectual climate through which the foundations of moral theology, good and evil, became open to question in the Church. Good and evil became interchangeable; they were no longer absolutely clear opposites. ”
