Churches
Lutheran
Germany, Scandinavia, Ethiopia, Tanzania, Indonesia, the Americas.
What it is
From the Reformation. Emphasises justification by grace through faith alone, and the authority of Scripture.
What to listen for
Law and gospel should both be preached — the diagnosis and the cure.
A label tells you the tradition, not the church. Two congregations under the same name can be entirely different. Visit the one on your road and put it through the questions from Scripture.
