There’s a USSC decision due out any time that will address this exact issue. And determine whether there is any religious freedom left in this country at all.
when is it likely to come out?
I'm not sure that case will cover this instance. In the Supreme Court case it's the plaintiffs that were denied service because of their sexual orientation. In this case it's a business suing for damages because the church forced them to turn down clients. This may have to go through the courts on its own.
