Why is the Church still struggling to get a grip on a scandal that emerged decades ago?

Surveying the ravaged landscape of the Church today, one question presses itself upon the viewer of the scene with palpable urgency: how did we get here?

There have been many answers to that question, none of them completely satisfactory. Some people say that the problem is the infiltration of homosexual predators into the ranks of the clergy. That is certainly a significant element of the crisis, but we need to ask far-reaching questions about how and why abusers were able to operate within the Church.
