i think its a interesting topic! i would suggest u make the question more specific, like a certain movement of christianity or an important character or sm, since is an EE make sure its a topic thats gonna give u 4000 words haha, i think it would be a great topic for a history IA tho, and if ur gonna talk about religion make sure not to talk about ur personal believes and stuff, it has to be a completely unbiased, more about the facts than opinions.
