Christian colleague is refusing to use my name/pronouns... Help?

I work with a 50yo-ish Christian man who adheres closely to the Bible and of all the people I came out to at work last week, he's the only holdout. Everyone else supported me enthusiastically, but he refuses to call me by my name based on his beliefs.

We had a meeting and talked about it (and I was SUPER nice about it in that moment because I respect him and his faith) and he still won't budge. He offered to call me by me last name and I said no way, non-starter. Also, I am trying to NOT involve my boss for the moment and resolve this amicably.

This person and I are supposed to meet again this week to discuss further. But really, I've got nothing... What am I supposed to do with this? What would you do?
