Title:
Martin_Luther

Context:
By 1526, Luther found himself increasingly occupied in organising a new church. His Biblical ideal of congregations' choosing their own ministers had proved unworkable. According to Bainton: "Luther's dilemma was that he wanted both a confessional church based on personal faith and experience and a territorial church including all in a given locality. If he were forced to choose, he would take his stand with the masses, and this was the direction in which he moved." From 1525 to 1529, he established a supervisory church body, laid down a new form of worship service, and wrote a clear summary of the new faith in the form of two catechisms. Luther's thought is revolutionary to the extent that it is a theology of the cross, the negation of every affirmation: as long as the cross is at the center, the system building tendency of reason is held in check, and system building does not degenerate into System.

Question:
What did Luther write as an outline of the new faith?
