I honestly do not think one has to "get on board," Eileen. But we must admit that there are those for whom this single issue is just that - a single issue - and tends to be the only thing about the ELCA that involves them. And for some of those people, it is true that their attitudes towards that issue will impact their ability to get a call. Would a congregation that is welcoming and supportive of same-sex couples and their marriage be forced to call a pastor with an exact contrary opinion?
Or, if a pastor who does not endorse same-sex marriage is in a congregation that supports his or her view, can that pastor and the congregation still take full part in the life of the ELCA, sending mission support, getting their kids to the synod camp and youth gatherings, cooperating with nearby congregations (which may have a partnered gay or lesbian pastor)? If so, fine. If they must become isolationist and withdraw from synod and ELCA activities, is that a good thing? I don't think so.
