I was going to do something like this. My Islam Quiz has been fairly popular even though QM thinks it's too difficult... I might still. If I had done this it would be a bit different.
A crusade isn't necessarily against Muslims. In fact its similar in definition to jihad --a holy war against heresy both physical or mental, social or individual. You should also accept holy ghost instead of spirit.
there were many crusades that targeted Jews, Orthodox Christians, even other Catholics in some instances. They didn't always go after Muslims. Also, if there was a Jesus he was likely born in Nazareth, in reality, should probably accept that as a type-in at least.
A couple of your questions are uniquely Roman Catholic-- Purgatory is a unique bit of doctrine from the Roman church, and the Cathedral/Bishop thing is also not universally Christian. Very few Christians consider Mormonism to be a Christian denomination, but rather a separate sect. Mormonism has about as much in common with Christianity as Islam-- a lot in common, but not considered one and the same. That said, pretty good for a user quiz.
The Pope's official words were that he 'got rid of Limbo'. Take that as you will. Some diehard Catholics have reinterpreted it as not referring to Purgatory, however. Either way, it's not 'just patently false'. And Catholicism is just about level on around one billion followers with Protestant Christianity. Not to mention that Mormonism really is not Christianity at all.
According to Catholicism Limbo and Purgatory are not the same thing. Limbo was where babies went who died before they could be baptised. Purgatory is where you go to be cleansed of sin before you can get into heaven (and the "better" you have been, which in some periods of history meant the more money you donated to the Church, the less time you spend in Purgatory). It's still ridiculous that the Pope can just decide stuff like that though. If it had really ever existed surely it would be God's decision. And what happened to all those babies who went to Limbo before it was abolished? Did they just disappear or did they go to heaven? Or hell or purgatory? Not that other denominations of Christianity are much better.
It's generally believed to be Bethlehem because that's what it states in the New Testament as well as stating that the Messiah's place of birth will be in Bethlehem in Ols Testament prophecies.
But even people who don't believe the Bible still associate his birth with Bethlehem because of the Christmas carols.
As he had brothers (and possibly a sister), it is obvious that she did not
remain a virgin.
Not all Christians believe this.
But even people who don't believe the Bible still associate his birth with Bethlehem because of the Christmas carols.
Holy Ghost: this is in the CoE Liturgy, among others
Palace: a building where bishops live
Luther: surnames are usually enough on this site, and in context, the adjective is Lutheran, not Martin Lutheran
None of the questions are hardly so obscure that only a devout Catholic would know the answers.
