Reason 30

30. Because Christ has only one Spouse, the Catholic Church, and her worship services cannot also serve religions that are at enmity with her.


There are a few major flaws with this argument. First, the singular nature of the Spouse of Christ has no effect on the remainder of the argument. No religion, properly speaking, can have worships serves which serve religions at enmity with it. Multiple religions can be served by one service when all the religions are so meaningless as to find no objection in the worship of another religion (why bother with separate religions, if that is the case?). This clause just is here to give the appearance of more weight to the argument.

Secondly and more importantly, this reason does the same thing Reason 25, that is, it assumes the New Mass serves religions that are at enmity with the Catholic Church. A properly celebrated Mass, whether the traditional or revised liturgy, is not accepted by Protestants as something good and akin to their religion. They found, almost universally, that the Catholic Mass is at enmity with their religion (unless they choose not to pay attention to what is actually happening and being said, then they might as well attend a Hindu service). There is simply no reason to assume the New Mass serves Protestants or anyone at enmity with the Catholic Church.
