Yes, the ELCA will have some difficulties with people who have blithely ignored our studies, conversations, ecumenical engagements, synod and churchwide assemblies, for 20 years; people whose pastors have not kept them informed about the broader mission and activity of the church; people who haven't engaged in Bible study since confirmation class, and people who have ignored the wider discussions in church and society (God is at work "out there" too) about a whole host of things. Suddenly they see something - often one thing - that surprises them and say "Where did that come from?"
I know some of those people and have hopes that, with patient prayer, study and counsel, they can catch up. Now I will duck for cover.
