Christianity is a religion. Adherents are called Christians. Followers of Christ, a manifestation of their god. The Holy Land is Jerusalem, where he ministered. It is holy to two other faiths, hence the fighting over who gets to claim it.
Understandable. If it brings you any consolation, from those who were here, who left, and who were returned again, it seems time does not pass the same here as it does in the worlds we come from. Some say they were gone for years while only minutes passed here. Others have spoken of being returned to their times, their worlds as though they'd never left.
Right or not, your circumstances may not be as dire as you think. And perhaps you could use this time to accomplish something you cannot in the heat of, as you say, fixing things.
