If you follow the logic of "any traditional Mass", then you are obliged to say that the crises in the Church is just about the Mass.
Sorry, is this comment directed at me?

Q: How would one be obliged to say that crisis in the Church is "just about the Mass" if one made a point of going to the Catholic Mass that God in his providence has provided for him/her nearest to ones home?
A: One isn't.
Q: Does the Church permit different views on the crisis in the Church, in particular the issue of what would happen if a Pope would fall into public heresy?
