Religion is an important orienting concept for societies so it is not surprising that anime has often dealt with it in many different forms. An article examining religion in Attack n Titan, Fullmetal Alchemist and D Gray Man would help provide for exciting reading. One could look at either the depiction of the organisation or religious themes within them.
That would be an interesting article. Especially in how Christianity is portrayed (or referenced). – OkaNaimo08194 days ago
