Is this question in reaction to the on going discussion of whether or not Mormons are Christians?
No it was from a discussion where a document from the 1800s was posted that had a problem with Catholics and Mary. That statement was made by a non-Catholic poster. Some of us were really taken aback.
Honestly, I never met, in person, a Protestant that thought Catholics were not Christians and I just wanted to know if my view was only narrow.
