That's the title of this article written by one pastor of the Evangelical Lutheran Church in America (ELCA). In it, he's asking the congregation he serves to leave the ELCA. But his arguments are as potent in supporting those who decide to stay in the ELCA and seek its reform and renewal.
The root issue of every flash point of controversy in the ELCA--whether it's universalism v. the Lordship of Jesus Christ, the notion of the Kingdom of God as something humans can create politically v. the Kingdom of God as something God is already bringing into being through Jesus Christ, or questions about human sexuality--is the authority of God's Word. Unless the Word of God is the ultimate arbiter of our life, faith, and practice, the Church is no longer the Church.
