Yes, many do just pick and choose the parts they want to see. In this case, the photographer as a business offered wedding photography. The courts correctly applied the law,“Once one offers a service publicly, they must do so without impermissible exception.” The courts held that: Elane Photography’s refusal to photograph Willock’s commitment ceremony violated the NMHRA (New Mexico Human Rights Act). No business can discriminate. If you wish to read the case you can find it by Google: elane photography llc v. willockAmazing how some just glaze over the parts they do not want to see and only read what they want to hear.
Were did it say that the photographer signed anything? In light of this, the photographer has the right to direct the "couple" to someone else. And for those of you who say Jesus excepted everyone, I say to you, read the Bible again. In fact read the exact words you have written, Jesus did not accept many and accepted only those, "such as sinners, who were open to his teachings, he was open to talking to." Your very words hit it on the nail. Now listen to your own words. He only accepts us if we accept him. This means we must strive to not sin. THIS DOES NOT GIVE US PERMISSION TO SIN.
1 Corinthians 6:9-11
"Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality,[b] 10 nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers will inherit the kingdom of God."
It is not a sin to photograph a gay service, however If they felt it was somehow a sign that they approved gay weddings, they need to get out of the service industry because the law does not abide by that sort of thinking. That goes back to civil rights. The law of the land. The bible is clear that Christians are to abide by the law of the land so it goes well for them.
From a Christian point of view, Jesus turned no one away (please show me where he did). In fact, he said,...whoever comes to me I will never drive away. He did show his distaste for things people did like the money changers in the courtyard or his pointed rebuttals of the Pharisees. And he made it very clear that there will be those who will be judged in a way they are refused entry into His Kingdom. THAT is where anyone gets turned away, but not until then. And those in that list in 1 Corinthians, are those who have not accepted Jesus. You are correct to say being saved is NOT a free ticket to sin, and we should do our best to avoid sinning, but sad to say, we still sin.
