" Jesus said marriage was from the beginning (Matt. 19:4–6). So neither we nor LGBT “Christian” activists have the authority to redefine marriage, or the biblical bounds of sexual relationships, or anything else that hits a cultural pressure point, any more than pseudo-evangelicals have the authority to redefine what the Evangel—the gospel—really is, which is what this is about. The Evangel isn’t a message where people write their own script. The “Evangel” of evangelicalism offers new life, but also demands repentance. How is the Evangel good news if it doesn’t offer freedom from sexual sin but instead baptizes it? "
