You know, you make a good point. Just as homosexuality is addressed in the Old Testament, adultery is as well. Now, certain religions have different views on marriage, remarriage, there are some laws that are just not done anymore (like plucking your eye out if it offends you etc…), however, your argument here does put the baker in a bit of a predicament, as it could be seen as certainly a hypocrisy. I still wouldn’t call it discriminatory, because again, different religions have adapted different views on marriage. However, going by a strict reading of the scripture, adultery is also considered wrong.
So, one would need to find out if a person has ever come into his shop and told Phillips he wanted to have a cake made for his 5th wedding (or whatever number), if Phillips has, then one would have a case that he is certainly hypocritical, and maybe even that he was not holding to his religious values.
Jack Phillips maintained he would 'serve everybody that comes in my shop,' but that he wouldn't 'create cakes for every message.'

He even says he wouldn’t make a cake for someone wanting a negative stance on lgbtq, he just doesn’t want to make a cake for every message that comes through the door, and a wedding is an inherent religious event and so he wouldn’t make one for a same sex wedding, which his religion opposes
