In Sins of Fathers, Donald G. Boland examines the moral responsibilities of contemporary Catholic clergy through the lens of classical logic, natural moral law, and the thought of St. Thomas Aquinas. Focusing on the Fifth through Eighth Commandments, Boland considers how actions, omissions, consent, and failures of leadership can carry serious moral consequences. His provocative critique challenges readers to examine questions of conscience, justice, truth, authority, and ecclesial responsibility in today's Catholic Church.
