Georik will be Canon Updated to chapter 5: Demon in the Church.

He tries to take Communion in church, but turns out - Holy Stuff now Poisons him (and this is after an Angel telepathically threaten him with tortrous death if he dare steps inside a church). After getting the crap beaten out of him by Mikhail, he ends up getting rescued by a mysterious seller of black market goods and now has an in-world supply of Alchemy ingredients.

Now anything religious/holy/light is going to burn him and he isn't going to voluntarily step on holy ground.
