“In the Reformed Church, as thus prevailing in different principalities throughout Germany, various catechisms appeared, and secured to themselves a more or less extensive use. In the end however all of these were either cast aside, or sunk into a secondary rank; while the Catechism of the Palatinate attained to a sort of universal authority, as the leading symbol of the Church” (J. W. Nevin, History and Genius of the Heidelberg Catechism (Chambersburg, 1847), 90).
