LGBT and SLU employment

I’m up for a staff position at SLU and realize that as a private, religious university, they may not be accepting of LGBT individuals.

I’ve been working at a public institution in Illinois for 20 years, so it’s never been an issue before. The SLU job is ideal because I need to move there to take care of my aging father, but I don’t want to get canned if I put a photo of my partner on my desk.

I do plan on asking the hiring manager, but I thought I’d check to see if there’s an obvious answer so I don’t look like a huge fool.
