The Reformation, sometimes called the Protestant Reformation, was a sixteenth-century movement to reform the doctrines (established beliefs) and practices of the Roman Catholic Church. The starting point of the Reformation is often given as October 31, 1517, when German monk and professor of theology (study of religion) Martin Luther (1483–1546) nailed his Ninety-Five Theses (arguments or assertions) to the door of Castle Church at Wittenberg in Germany. These theses attacked the corruption of church leaders and the doctrines of transubstantiation (the teaching that the bread and wine of the Eucharist, the celebration of Christ's last supper, is actually transformed into the body and blood of Jesus Christ), clerical celibacy, and the pope's supremacy. Although calls for church reform had been voiced in the past, it took Luther and his theses to ignite the movement.

The movement was actually to bring the church back to Biblical mandates and salvation by grace alone through faith in Christ alone. It is good to think that there were men who cared enough to do something about all the things going on in the church at that time.
