The bakers’ argument is simple yet problematic – “I don’t want to help somebody celebrate a commitment to a lifetime of sin… The Bible tells us to flee from sin. I don’t think making a cake for it helps.”
But there’s simply no Biblical command for Christians to deny services to those whose actions you believe to be sinful. If there was, who could Christians serve?
