We consider these to be the four most essential books that a Catholic should have (not counting the Bible, of course). The Imitation of Christ has long been considered the greatest Catholic book behind the Bible. It and another classic, True Devotion to Mary by St. Louis de Montfort, were proclaimed as the most hated books (not counting the Bible) by the demons when the priest commanded them to speak the truth in a particular exorcism. The Mass Missal and the classic devotional, The Pieta Booklet, are particularly recommended in a private revelation. We believe that we are in the end times, which makes having these books especially important, but regardless, these books have all earned classic status and belong in your library and in your purse!
