You forgot to add orthodox chrisitanity in your pool.
Did you forgot about russians,serbs,bulgarians,romanians,greeks,armenians?

I assume that falls under one of the 3 categories of Christianity that I listed?
Is that not Catholic? Then choose Christian - Other
lol, with this question you earned yourself some serious friends!
I thought half of all members here are from russia or around.
Hopefully they will forgive us.

We are sinners!
Why isnt there a choice for just christian, which I would prefer....if.
Before the 20th century, Christians did not identify as such...
The only reason they fly the same flag today (Christian) is so they outnumber the Muslims... If you simply remove the Catholics, Christians are the 4th largest religion in the world...
Having been a Christian, I know firsthand they do not believe the same dogma... As a protestant, I had been to various protestant churches (baptist, pentecostal, etc), but never a Mormon or Catholic church (discounting Cathédrale Notre Dame de Paris)... there is a clear separation in beliefs and practices...
