The National Catholic Register is preparing a story on how priest seminars on training for the extraordinary rite are filling up. True. There is one seminar that is not yet full: St. John Cantius and the CMAA, Missa in Cantu, October 17-19, 2007. It is not exclusively for the old form. The purpose is to train celebrants of the Roman Rite to sing, sing, sing the Mass, as a means of ennobling the liturgy - English and Latin. It is about half full now, which is pretty remarkable given that it is two months away.
