Well this is really a broad topic....what exactly do you mean? LIke looking at the Bible what is our impression of them? Have we ever seen any? Do we think they're super duper important, or just another peice in God's almighty army?
yeah, of corse there real. if you're a christain, you believe the bible, right? well you have to believe the whole bible, and angels are in the bible, so if you're a true christain, you believe in angels.
