Until now, the Church has protected itself by preventing anyone other than the Pope from calling a council to reform. He believes that anyone who discovers a problem in the Church should be able to convene a council. The convening of a church council depends not on authority, but on spiritual need. Furthermore, Luther delegates the temporal authorities as best suited to call a council, because they are fellow Christians and have the power from God to exercise power. In his treatise he says: “Moreover, they can show nothing in Scripture giving the Pope exclusive power to call and confirm councils. » he says that because we [the clergy and the pope] think that we are the only ones who have the right to call an ecclesiastical council, we are heretics. Martin Luther challenges the doctrine of the Church that our Lord and Savior established. Luther defines the priesthood of all believers as God being accessible to all believers. This Protestant doctrine allows all Christians to exercise their own ministry and pray without recourse to a bishop or minister. With this belief, there is no hierarchy in the church, so a milkmaid can be a priest. He tells Christians that these two tasks [their strengths] are what God has called them to do.
