In Light from Darkness, Steve Weidenkopf challenges extreme reactions to the Church’s current crises by looking to history. He argues that past eras were just as turbulent, with corruption, heresies, and external threats, yet the Church always emerged stronger. Weidenkopf presents nine historical cases where faithful Catholics—both clergy and laity—helped reform the Church from within, resisting despair and complacency. By drawing lessons from these periods, he offers hope and a blueprint for Catholics today to navigate challenges with faith and perseverance.
