Luther believed salvation and Calvin believed predestination. Luther held that salvation comes by faith alone. He emphasized that women and men are saved by the arbitrary decision of God. He also revealed that God could grant the gift of salvation. The idea that priests or the Church had special powers was rejected. All Christians had equal access to God through faith and the Bible. Luther translated the Bible into the German vernacular. He defined consubstantiation which is the belief that after consecration the bread and wine undergo a spiritual change whereby Christ is really present. However, John Calvin believed that the body and blood of Christ are spiritually but not physically present in the bread and wine. He believed predestination which is that the belief of God or fate has decided what will happen to people and no one can change it. In opposite to Luther, he emphasized that men and women cannot actively work to achieve salvation. Predestination served as dynamic, forcing a person to undergo hardships in the constant struggle against evil. In common, both of them believed in supremacy of the bible and Holy Communion and baptism.
