Trying to find an SCP

The wiki search has gotten way better, but I'm strapped for what keywords to try for this one.

Fairly certain it's a single SCP I'm remembering. It followed an agent sent to investigate a small town, which I think they actually grew up in? I can't recall any details of what the actual anomaly was beyond being something eldritch-y, and I swear the climax involves the town priest using/abetting the monster for white supremacist reasons.

Ringing any bells? Would not be shocked if I ended up mixing it up partly with some movie/show.
