"What they are not entitled to do is pass on their own personal beliefs as Catholicism."

Eh, which is exactly what you chose to do when you left the Roman Catholic Church and went elsewhere. Then upon your return you won't associate with your fellow parishioners because you, in your own words, would regard that as "scandalous."

What kind of message did that give to your kids? I assume they are now adults, where do they attend, Anglican or Roman Catholic, or not at all?
