A significant Christian figure who has contributed to the discipline of Worship is Martin Luther. It is important to note that "Congregational singing was almost eliminated in the Middle Ages. For over 1,000 years nearly all church singing was done by priests and professionals.” “At the heart of Martin Luther’s reformation of the Church were his reforms in worship.” Martin Luther brought about great changes in worship by his petition to have the word heard and sung in the language of the people throughout the service. This reform of worship gave freedom for the congregation to express their hearts before God in song, music and hymn.
