 In the same year of 1542 , Calvin published Catéchisme de l 'Eglise de Genève ( Catechism of the Church of Geneva ) , which was inspired by Bucer 's Kurze Schrifftliche Erklärung of 1534 . Calvin had written an earlier catechism during his first stay in Geneva which was largely based on Martin Luther 's Large Catechism . The first version was arranged pedagogically , describing Law , Faith , and Prayer . The 1542 version was rearranged for theological reasons , covering Faith first , then Law and Prayer .
