Protestantism formed from the split with Roman Catholicism during the Reformation in the 16th century. Led by Martin Luther, John Calvin, and others, the reformers broke from the Roman Catholic Church due to abusive ecclesiological structures and theological differences. Protestants share an adherence to the centrality of scripture (both the Hebrew scriptures and the New Testament) as well as a doctrine of salvation through faith in Jesus Christ.
