So I guess if my boyfriend and I requested a cake as a heterosexual couple, he'd do his diligence and question us about our beliefs and lifestyle? Perhaps require I submit proof of virginity? Otherwise he'd be investing his creative soul in making a cake celebrating the marriage of two atheists who are currently living in sin. And what about the fact that I have no plans to "obey" my new husband? Certainly that violates biblical teachings, and is not the sort of marriage Mr Phillips talents should go into celebrating. 

Of course, it's also possible that what many religious people present as a consistent, vital application of their faith is instead cherry-picking what they feel like putting into practice from their religious texts. Don't get me wrong, in some ways that's a good thing (despite living in sin, blaspheming, disrespecting my parents, and a multitude of other "sins", no one has ever tried to stone me). But it doesn't give much credence to talk of biblical teachings.
