Fr. Fessio, recently fired and (following a HUGE reaction by students/donors/alumni) rehired under a different capacity at the giant mess which is Ave Maria University, gave a series of talks about the Moto Propio. If you are interested in the subject, there are few men who are better suited to explaining it.
