The ELCA has structured itself not simply with synods and bishops and assemblies and rules. It has structured itself so that it no longer lives by the Word of the Lord as the sword of truth and life. Instead, the ELCA has time and time again replaced the clear Word of God with positions that accord with the prevailing views of liberal Christianity and a progressive culture embarrassed about talk of sin and redemption. So what will happen? The structure designed for a church body nearly twice its current size will be thinned out and flattened but you can be sure that the sacred minorities will retain both their influence and their bureaucracy while the rest of the church's mission will be rearranged around these essential causes (sex, gender, race, social justice, and climate change). And the bleeding will continue until another reformation is required because even that structure is too cumbersome for those who will be left in a graying and white church body that so desperately wants to be seen as relevant by everyone except the God whose judgment matters.
Lessons learned here about but chief among them is that the renewal of the faith begins with the Word of God, with creeds and confessions faithfully written, and with an urgent commitment to uphold them when unpopular and rejected by the world around them. The Church is not failing for lack of accommodation but precisely because the causes du jour of culture and society have replaced the Gospel as the beating heart of Christian truth and life. Jesus is not an idea and love is not a concept and this life is not our primary focus. Learn that and any apostate church just may have a future but cling to these ideas and there is no tomorrow except a continual downsizing and reformation of form instead of faith. If you embody the Word, you don't need to listen to it, apparently.
