Not sure where you're going LFS?  But if you believe he can discriminate on hiring and policy based on religious beliefs, he cannot. he should not, be allowed to serve in a public position representing ALL of his constituents.

I wonder what the context of his online post was?     You may be practically right that if he keep his faith private (not shouting it from a street corner), he probably wouldn't get in trouble.   

In Iowa years ago, they fired a state employee for holding what amounted to mandated prayer during work hours, and discrimination in the hiring process by inquiring about faith practices.    I would assume this would be the case with Vought regardless of what he may say online.
