To avoid confusing or upsetting the people, Luther avoided extreme change. He also did not wish to replace one controlling system with another. He concentrated on the church in the Electorate of Saxony, acting only as an adviser to churches in new territories, many of which followed his Saxon model. He worked closely with the new elector, John the Steadfast, to whom he turned for secular leadership and funds on behalf of a church largely shorn of its assets and income after the break with Rome. For Luther's biographer Martin Brecht, this partnership "was the beginning of a questionable and originally unintended development towards a church government under the temporal sovereign". The elector authorised a visitation of the church, a power formerly exercised by bishops. At times, Luther's practical reforms fell short of his earlier radical pronouncements. For example, the Instructions for the Visitors of Parish Pastors in Electoral Saxony (1528), drafted by Melanchthon with Luther's approval, stressed the role of repentance in the forgiveness of sins, despite Luther's position that faith alone ensures justification. The Eisleben reformer Johannes Agricola challenged this compromise, and Luther condemned him for teaching that faith is separate from works. The Instruction is a problematic document for those seeking a consistent evolution in Luther's thought and practice.
