What a ridiculous and uninformed statement!
I’m fascinated by the number of “I’m now a Catholic but I used to be an unsaved Protestant” posts that show up here.
All I know is that we’ve met dozens of ex-Catholics at our non-affiliated community church over the last few years, and since it’s a big place (22,000 for Easter worships) I’m sure there’s a lot more where those came from.
If Maryolatry wasn’t such an entrenched tradition the Catholic beliefs might be more compelling, but... there you go.
