Abstract: Protestant theology contains the doctrine of justifing by faith without good works and religious law. This doctrine has been the main reason of firm predestination idea. It also led the Protestants to religious irresponsibility in their earthly life. It has also been followed by moral indifference or being against moral laws as known antinomianism. The famous Lutheran reformist and Martin Luther’s close friend Philip Melancthon has tried to found the Protestant morality on the base of religious feelings, but could not success it. Consequently, it must be stressed that the world is under the thread of the understanding of Protestant immoralism which is based upon religious irresponsibility and predestination.
