BTW, William of Ockham is the the source of the Heresy of Nominalism which is the main heresy of our times. Why doesn't someone write a book on that and how it is employed by the conciliar church?
.
Ed Feser hasn't done exactly that, but most of his work engages the problem of nominalism directly or indirectly, and how it is employed
writ large by modern thinkers, whether religious or otherwise.

Back on brand, if I might ask a question about Fr. Chazal's book, how well does he engage what authors who
aren't Fr. Cekada have to say? SGG/MHT are no more conflatable with "sedevacantism" than the SSPX is conflatable with "sedeplenism."
