Luther was sent to the diet of Worms, the highest people in the Roman Catholic Church. They told him to stop doing things but once again he refused.
Luther was hidden by his supporters until the church left him alone. In total he hid for about 2 years. While he was hiding, he wrote many letters attacking the church.
The church lost most of its followers and decided to give up and stop arguing with Luther. They stopped selling indulgences and telling false information. To this day, thy have never had as much power as they did before Martin Luther.
