1) Well the codename the Christian could be way better, its not as if he's the only Christian in the world. There are all kinds of religious-themed codenames that would fit much better. 

2) LA doesn't have to be on the sheet because it's not his place of birth but that's a cosmetic issue, no big deal. 

3) You don't explain what Santanas is so it doesn't really make sense in his affiliation tab. 

4) Are they crosses of wood or what? Because creating a random solid object out of nowhere is a bit beyond the reach of a non-sorcerer, but I could buy them being crosses of light or some such. Also Holy Mode should not be able to tear through worlds, that's way too overpowered. In general this mode needs to be expanded on and its specific capabilities described. 

5) The whole setting atheists on fire thing would be considered assault. So if you don't want your character to be a convicted felon you may want to downgrade that. 

6) I have trouble believing Jesus would appear for one person's prayer out of basically anyone else. Just a nebulous holy presence should suffice. 

7) You can expand on the bio more, like his reason for being in Chicago and joining a League of metahumans and supernaturals, some of them atheists. And you should edit out the last two paragraphs from the skeleton :P
