Cripplegate has two good posts in light of the firestorm surrounding Chick-Fil-A and Christians who oppose same-sex marriage on the basis of biblical truth.
Objection #1: “There are plenty other commands in Scripture that Christians don’t follow today, like the prohibition against mixing fabrics (Lev 19:19) or eating shellfish (Lev 11:10–12) and pork (Lev 11:7–8). So why not one more?” Response
Objection #2: “In the midst of all of your attention to details of various Bible verses, you’ve lost the big picture. The cardinal virtue that Jesus taught His followers was love. If you value love, what’s the problem with two consenting adults making a commitment to each other out of love? Love is love. To insist that homosexuality is sinful and to deny them the right to get married is simply not loving, and therefore not Christian.” Response
