How did Martin Luther's efforts lead to the end of Christian unity in Europe and the beginning of Protestantism? Make sure to give at least two examples of his impact and cite evidence.

The Roman Catholic church considered itself the representative of God's people and kingdom, but its ways were not according to the Scriptures. The Pope promissed deliverance from Purgatory with "Papal Indulgences", which Martin Luther defied, so he nailed 95 Thesis to the church door, explaining that Salvation is by faith, not works. The Reformation started. This was the beginning of the Protestantism and the separation from the Pope and Roman Catholic church dominion.
