Justice without mercy is cruelty, but mercy without justice is the mother of dissolution.
St. Thomas Aquinas
The clerical sex abuse scandal was made possible because of a prevailing mentality, especially in the 1970s and 80s, that notions of crime and justice had no place in the post-Vatican II Church.* The crimes of clerical abuse were labelled as “struggles with chastity” and “mental issues” and there was an entire cottage industry of therapy centres and clinics which would helpfully label the abusers as victims of their own traumas, often blaming it on the wicked institution of clerical celibacy, and then “rehabilitate” abusive priests and send them back, certified as ready for ministry. This approach, which was consciously identified as a “merciful” way of handling matters, caused a chilling illustration of what a mockery of itself mercy can become when it is uncoupled from justice.
