The Supreme Court recently voted to hear an appeal from the owner of a Colorado bakery who refused to bake a wedding cake for a same-sex couple.

The high court will hear arguments for the case in its upcoming 2017 term, which begins in October.

The case will consider whether shop owner Jack Phillips, who objects to same-sex marriage based on his religious beliefs, was exercising his constitutionally protected rights when he refused to bake a cake for Charlie Craig and David Mullins’ same-sex marriage.

Phillips said that his constitutional rights to freedom of speech and religion were violated when the Colorado Court of Appeals ruled in August 2015 that he was required to bake a wedding cake for the gay couple under Colorado’s Anti-Discrimination Act. The baker said he honors God through the art of decorating cakes and that it would displease God if he were to bake a cake for a gay marriage.

“I feel that the Bible is clear — what God defines marriage as,” Phillips said in 2015. “For me to violate that would be for me to rebel against God, to take what he’s designed and say it doesn’t matter.”

But Craig and Mullins claim they were discriminated against by the baker for his refusal to make a cake for them in 2012.
