Homosexuality is sinful behavior. Love the sinner, hate the sin and all that fine. I cannot see a Church promoting immoral, sinful behavior by elevating an openly homosexual person to a position of religious authority. Me and the ELCA are almost certainly going to have a parting of the ways over this one.
If you want to remain Lutheran, you may already know this, but the Lutheran Church Missouri Synod is apparently still quite faithful to scripture.
