“Calvin was the friend of a plain but orderly and solemn form of worship. The liturgy which bears his name has been composed from material of the forms of worship used in Strasburg and other places. He is in favor of brief prayers. ‘It is better to pray at length in private and briefly in the assemblies. If thou expectest from all an ardor equal to thine own, thou art mistaken.’ He favored the singing of the psalms, which was deemed so important, that it became almost a kind of profession of faith; ‘psalm-singer’ and ‘Reformed’ were almost synonymous words in France.” — Philip Vollmer, John Calvin: Theologian, Preacher, Educator, Statesman (1909), pp. 54-55
