Rigth now all I know is that the Cardinal will say the first one in September. After that whoever gets the nod will do it every week, at least that is what the Presbyterate Council meeting notes seem to suggest. The Cardinal was upset that people from his diocese had to go to Windsor to attend an Indult Mass or go to a Schismatic Mass (his words), I think there are several in the Detroit area. As far as I know no announcement has been made about where the Masses are to be said but there are suppose to be two places.
