Without institutions, where would we be? But they are all corrupt, potentially if not actually, in part if not in whole. The Roman Catholic Church is no exception despite its claim to divine sanction and guidance.
Bernard Law died yesterday in Rome at the age of 86, a pariah who was granted a kind of protective custody in a Roman basilica by the Vatican.
Law, who distinguished himself as a civil rights activist while serving in Mississippi and Missouri, came to act as the chief facilitator of the sex abuse scandal that rocked the Boston archdiocese and sent shock waves across the nation and around the world. (here)
You should be skeptical of all institutions. Like the houses out here, they either have termites or will get them.
But institutional corruption reflects personal corruption. So you should be skeptical of all persons, including the one in the mirror. Especially him, since he is the one you have direct control over.
