I think this is where the misunderstanding is...
They are leaving Father's Mass circuit - a Mass circuit is where a priest will travel to different chapels to service the needs of the faithful. So, when I worked at the SSPX retreat house in Los Gatos, for example, I used to drive Fr. Alphonsus all over the state of California to serve different chapels. His Mass circuit went out to Bakersfield, sometimes out to San Jose, Sacramento, etc.
The priest in this case is driving all over to serve different chapels. Some of those groups have now cut themselves off from his circuit.
Thank you for finally explaining that. So, some groups are no longer attending masses because of +W's statements, which are statements that he has made many times in the past, and which nearly everyone on this forum has known about for a few years. I still don't get why they would suddenly be leaving. Very odd, but okay. That's their choice. I guess it's worth it to them to not have access to the sacraments over this issue.
It seems to back up what Matthew has said on this thread regarding home-aloneism.
