“Isn’t it better to attend the New Mass, than not attend at all?”

The evidence that you cannot attend the New Mass and must stay home (if there isn’t an acceptable traditional option) is contained in the dogmatic teaching on the form of consecration from the Council of Florence, Pope St. Pius V, etc. It is also contained in the teaching that “all” in the consecration cannot suffice for validity, and that it is a grave sin to approach doubtful sacraments. It is also contained in the traditional teaching of the Catholic Church that one cannot partake in non-Catholic worship, and the New Mass is a non-Catholic service which was invented by heretics and with the help of Protestant ministers. It was intended to Protestantize Catholic worship, and includes condemned practices such as altar girls. To a sincere person who considers this evidence, it becomes clear that one cannot attend the New Mass under pain of mortal sin. You are not worshipping God truly by going to the New Mass, and you are not receiving Jesus Christ in Holy Communion.
