The church has to stand, as you say, and as much as I gripe about how they ignored the whole process until now, I am grateful they are standing, even as I’m fearful *they* will cave. As, in fact, they have been for a generation or more.
As others have pointed out, the Bishops don’t have the authority to give in, except on behalf of their individual dioceses. Faithful Catholic institutions are filing legal challenges, and they’re not going to withdraw them if a Bishop or the USCCB says a suitable compromise has been reached.
However, the heirarchy is missing a golden opportunity to place the American Catholic Church at the national level on the side of freedom for everyone and Christian moral values as a good for everyone. Even if they don’t reach an agreement with the Zero administration, they’ve already shown that they don’t “get it” regarding what is going on.
