At any rate, if you believe that the bishops in union with the Pope are capable of instituting an invalid Mass and depriving the whole Catholic Church of valid sacraments, then you obviously do not believe in the indefectability of the Church.
Its true that the Churchs infallability doesnt extend to pastoral matters, but its authority certainly does. Do you go to Mass on a holy day of obligation? Why? Jesus never commanded that we must attend Mass on Holy days-- the feast of the Assumption, for example. That was a pastoral decision of the Church. Why do you consider yourself bound by that decision, when at the same time you deny that the Churchs authority extends to pastoral matters?
I seems to me that others who have been arguing with you are correct. You have become a Protestant. Your complaints against the Church may be different than those of the sixteenth-century Protestants, but the principle is the same. You both believe that the Church failed in a critical aspect of its mission, so much so that you must separate yourselves from her communion and worship elsewhere, in the backwaters and caves with the rest of the faithful remnant. The Protestants believed that the Church had corrupted her doctrines; you believe she has corrupted her sacraments. In both cases there is a lack of faith in the indefectability of the Church.
I have to go to Mass. I will pray for you.
