What were Martin Luthers chief objections against the Roman Catholic Church?
In general, Martin Luther was against the supposition that the Pope could absolve sin by means other than granting abolution, such as by the sale of indulgences. The church was spending most of its time collecting monies in the name of the forgiveness of sins through the sale of indulgences and praying for the dead, that they were not ministering to the needs of the living and unforgiven.
