St Pius V participated in evils, at least according to the standard applied to others in his time. Just looking for clarification, in light of a world of sin. I think we'd both agree that ISIS consists of no Catholics regardless of temperature. The lack of response to their depredations from the US is evil IMO, and I doubt Catholics would claim another Dem pol like 0bama in their orbit.
Ans what “evil” would that be that Saint Pope Pius V participated in? He is one of the Catholic Church’s greatest popes and saints.
