re: Who has a sibling that refuses to acknowledge your existence?

Look, if you feel like you need some engagement with your brother, and I get it, he's your brother, tell that holier than thou dipstick that Jesus would go to your wedding. Jesus dined with the tax collector, and walked among the sinners BECAUSE they were sinners. If that doesn't work, then he really doesn't know the God that he worships and he's too far gone.
