medieval-religion: Scholarly discussions of medieval religion and culture Colleagues -- I am having trouble finding the first use of the phrase _ex opere operato_. Over and over I read that Peter of Poitiers invented the term in the early twelfth century, but none of my sources provide a reference to the specific place where he does so. Can anyone help? Thanks in advance.
