Compare this case to Jim Crow in the South. Once there was a federal court order demanding that blacks be allowed to register, could a KKK refuse on biblical grounds. The cross is central to their organization. They believe in good faith that the Bible says blacks are cursed.
When I was a child, this was unthinkable. I did not know homosexuals existed until I quite old. During my happy years living in Greenwich and the East Village, I met many gays. My churches were welcoming - which has become a code word. If the ad in the newspaper says it is a welcoming church, gays know they are safe to attend. I am curious as to why this code remains. Knowing specific people changed my mind about gays. Things have moved a long way since the Stonewall Riots.
This is similar to choice issues, too. Can an insurance company employee refuse to touch abortions claims. Abortion is a const'lly mandated right, not a privilege. It puts the insurance company at peril for suits by the states attorney-generals and claimants.
I read cases about employment discrimination vis a vis religion. It is not an absolute right. Employers do not have to change their policies in order to accomodate an employee. A recent case involving the Salvation Army held that the Salvation Army could discriminate based on religion, despite strong federal laws against such discrimination in general. Sadly, I don't remember the details or the overriding principle. Employers do not have to place religious objectors on the dole.
