Most Catholics don't understand or reject a lot of Church teaching.

Rejection isn't a measure of truth.

The Church has weathered just fine rejection by many.  

Rejection can and should be sanctified.   But many Catholics - a disproportionate number here - don't really understand what I mean when I say that rejection can be sanctified, or when I say that any difficulty (or joy) can be sanctified.

They haven't been formed well enough by the liberal bishops they love to understand these ideas of Jesus Chris.
