Some people may think this Baker is an asshole but if he is a true follower of Jesus and trying to live the sermon on the mount, he couldn’t in good conscience supply his talents to help celebrate something he believes to be a celebration of a transgression against God(sin). Jesus himself says that followers of Him will have to choose between the laws of man and the law of God.
The reason that a lot of followers of Jesus see a difference in discrimination between sexual orientation and race or gender can be described like this:
Gender or race are endowed by the Creator. You don’t choose to be black, white, brown, red, male or female. Those are sacred and I don’t think a person truly trying to follow the teachings of Jesus could defend discrimination against those sacred qualities that can only be ordained supernaturally.
Followers of Jesus see marriage in the same way. It is a sacred institution established by God between a man and woman and the baker could not in good conscience apply his talents to celebrate something that transgresses a sacred gift from God.
In this case the baker said the gay couple could buy a cake from his bakery that is already made and use it as they wish. He just couldn’t use his artistic talents to help them celebrate something he disagrees with based on religious belief.
You may disagree with everything I wrote and that is fine. We have that freedom in this country.
You may disagree with all the beliefs of the baker and that is fine too. I imagine in America today the majority believe sexual orientation isn’t a choice. I think in this baker’s mind he would differentiate sexual orientation with acting on sexual orientation.
I would wager to say he would liken the decision to act on sexual preferences the same as the decision to act on a predilection to alcoholism, pedophilia, lying, or any other number of vices that are held to be sins by those trying to follow the teachings of Jesus.
If he were a wine maker I doubt he would serve a drunk man a bottle of wine or if he was a taxi driver, drive a pedophile to the local elementary school if he knew the intentions of the person were to have a sex act with a child.
They may not be equivalent in the eyes of the law of the land but there is some equivalence between the examples just given and the celebration of sexual sin from the Followers of Jesus perspective.
Until we are ready to outlaw beliefs except those established by the government, then we supposedly still have religious freedom in this country and I don’t see how the court could have ruled otherwise that they did.
