The liberal wing of the Lutheran church. Like Jesuits in the Catholic church.
While not Lutheran myself, I have many close friends who are lifelong ELCA members. It’s been appalling watching the denomination destroy itself over the past few decades. It’s also been disheartening watching ELCA members either tie themselves into theological knots defending the denomination or seethe in frustration as they watch their beloved church plummet deeper and deeper into heresy.
