- Who Decides and With What Authority?
Apr 19, 2024 • 39 min
Professor Michael Root explores the question of who has the authority to make binding decisions on matters of faith within Christianity. It traces the historical development of this issue from the early Church through the Reformation, highlighting Luther's principle of sola scriptura and the concept of private judgment in Protestantism. The speaker contrasts this with the Catholic understanding of authoritative decision-making through councils, papal declarations, and the guidance of the Holy Spirit, emphasizing the ability to close questions definitively in Catholicism versus the potentially "fissiparous" nature of Protestantism. This lecture was given on February 3rd, 2024, at the Dominican House of Studies.
