“The greatest attention was paid to catechetical instruction, in the Netherlands. The duty was pressed upon heads of families. Schools were required to cooperate with the churches, in carrying the system into full effect. The pastors must preach on the Catechism every sabbath afternoon; besides visiting the schools frequently, and holding catechetical exercises, if possible once a week, in private houses. All pains were required to be taken, to secure in this way to old and young the benefit of religious knowledge” (J. W. Nevin, History and Genius of the Heidelberg Catechism(Chambersburg, 1847), 98).
