This catechism can be considered as a valid and effective catechetical tool for the work of the evangelization, a work which has to be realized with a new missionary zeal towards those who don't know the Catholic faith and as well towards those who know it defectively and insufficiently. May those who will read this catechism and those who will use it in the noble and meritorious work of teaching Christian doctrine, may be equipped with the sure and sacred doctrine of the Catholic faith, in order to stand, having their loins girt about with truth. -Bishop Athanasius Schneider This is the first English translation of St. Robert Bellarmine's Long Catechism, which follows a traditional question and answer model but gives deep meditations on the truths of faith. It was written for students with some education as well as for those who would teach Catechism. It was explicitly approved by Pope Clement VIII and praised by Pope Benedict XIV and Pius XI. St. Robert Bellarmine is a doctor of the Church.
