Good point, sir. Those that I have known or known of to stop acting as Catholics, though, may CLAIM that it’s because of the theology, but normally use that as an excuse to avoid the rigours or the regimens of practicing the faith.
A lot of people (reminiscent of so many posts here) don’t like kneeling in prayer - as it says in the Bible. It’s too darn humbling. So they go somewhere where they don’t have to.
Heck, most of the non denominationals that I’ve been in don’t do a whole lot of prayer at all. They will have a couple of people at points in the service come on and ramble on for a few minutes, but very little real or community prayers at all.
I work with a couple of fervent attendees at a spreading church with about a dozen locations now and I asked them what they did for Easter. One cut his lawn. The other visited his sister. They didn’t even attend their own services that day. When I asked them why they didn’t honor the resurrection of the living Lord, they each gave me variations on “works won’t get you into Heaven.”
It’s easy when you really don’t have to attend church if you don’t feel like it.
They don’t fast. They don’t do penance. It’s easier when you don’t have to imitate Christ’s actions in any way or even confess your sins, as it says in the Bible.
I posted the definitions of heresy and blasphemy some time ago. I notice that the objections appear to have lessened when these words, objectively applied, appear.
