The aim of the Reformation was not the abolition of the priesthood but the abolition of the laity. Every Christian was to realize his priesthood: ‘Ye are a chosen generation; a royal priesthood, an holy nation, a peculiar people; that ye should show forth the praises of Him who hath called you out of darkness into His marvelous light.’ This is the Biblical conception of worship—an offering of the entire congregation in praise and adoration. The Reformers aimed at restoring this heritage to a people who had become accustomed to being spectators at a ceremonial in a language they did not understand. They therefore insisted on everything being said at worship in a clear and intelligible voice in the language of the common people. They also encouraged the revival of congregational singing and audible participation in the Lord’s Prayer and the Apostles’ Creed. They restored the practice of regular reception of the Lord’s Supper in both elements, and indeed wished to make this the normal weekly worship of the Church.
