“If the Mass isn't valid, what am I supposed to do?”

Thanks for the e-mail.  The Third Commandment (Keep holy the Sabbath) is God’s law.  Attending Mass on Sunday and Holy Days is the Church’s law, which is only obligatory if the Church provides you with a true Mass and a truly Catholic priest within a reasonable distance.  There is no obligation to attend a false Mass; in fact, there is a positive obligation under pain of mortal sin to not attend the New Mass, since one cannot approach a doubtful or invalid sacrament. If you are committed to not attend the New Mass and you hold all the dogmas, there might be a place for you to attend the true Mass depending on where you live (please let us know), but if not you just stay home on Sunday and sanctify the day by praying your rosary.  Many of these questions are answered on the website, and I would strongly encourage you to get our DVD special since these issues are covered in great detail.
