This whole discussion has become another great example of goalpost moving.
Catholics regularly tell non-Catholics they are going to hell since they are heretics and have ex-=communicated themselves, which effectively damns them according to Catholic teaching.
Matter of fact, Catholic think it’s presumptuous for ANYONE to claim they are going to heaven.
Besides that point, Catholic teaching itself is replete with condemnation for people who don’t submit to Rome.
So finding a post where Catholics telling others they are not Christian might be tough, but they do tell them they are not saved cause they are not Catholic and don’t eat Jesus.
I've never seen this, really I haven't -- but I'm betting you have.
If it's a FReeper Catholic, give me his/her FReepername and I will sally forth and whomp them with my Catechism.
