I don't know why you people even try to argue with Mr. Catholics aren't Christians.

That was a stupid comment. I took that question from the wrong perspective. My opinion was that Catholics were different because they don't believe salvation comes though Jesus' death solely, instead believing that a priest can pray you into heaven among other oddities not found in the Bible. Oh well. My bad
I have never heard this one before.
For real? You've never heard of the phenomena of purgatory?
That's where my issues always come up. Although the various branches/denominations of Christianity differ on many issues, there are about 5 fundementals.
1. Mary was a virgin (Virgin Birth)
2. Diety of Christ
3. Salvation is through Jesus Christ's death (Grace through Faith)
4. Resurrection of Christ
5. and to a less extent, belief in Jesus' miracles
Obviously Catholism is big on #1. They believe in the Deity of Christ. They believe in his resurrection. They believe in the miracles. But their believe on the most important fundemental Christian belief of salvation through Christ is rather iffy. They do believe in being "born again", but this is brought by baptism into the Catholic faith according to their teachings, and not through Christ.
This is where purgatory comes in. Catholics believe that you go to purgatory if you have unforgiven sins, which directly contradicts every teaching of fundemental salvation; Christ died for all your sins more than 2000 years ago, and they are all forgiven already. With this in mind, how would it be possible to go to purgatory? And as I said earlier, they also believe that one can be prayed into heaven by way of penance. In other words, if you died in real life and went to purgatory, people who were still alive could pray for you and take years off your sentence, so to speak. Once again, this is nowhere in the bible.
That being said, I have nothing against Catholics. They do a lot of good in the world, and I respect that. But my concerns about some of their practices, and the fact that some would place them alongside fundemental Christians, remains.
