Editor’s Notes

This article reproduces the entirety of Causa XXIV, Quest. I, along with Gratian’s commentaries.In an accompanying article, I have explained the history, context and interpretation of the so-called canon Audivimus, and its relevance to any excommunications which may be levelled by Leo XIV against the SSPX and other traditionalists.
