"The whole problem of "pornovision" and of "pornography," as it appears on the basis of what was said above, is not the effect of a puritanical mentality or of a narrow moralism, nor is it the product of a way of thinking burdened by Manichaeism." --Pope John Paul II, Theology of the Body, 62

It's understandable. People make mistakes. It's a big book.
