Hidden Treasure of Plenary Indulgences
Rev. Pius Massi, S.J. Impr, 1906.
The purpose of this book has been to spare trouble for the faithful by providing them with an exact and authentic list or catalogue of some spiritual works and prayers to which is attached a Plenary Indulgence that may be gained once or oftener each month, so that by the fulfilment of what is prescribed, one may gain every day of each month one or more Plenary Indulgences. Presented is only those Plenary Indulgences which may be gained one or more times each month, prescinding entirely from all other Plenary Indulgences which may be gained on other occasions, e.g., on certain immovable feasts, such as Christmas or the Immaculate Conception, or on movable feasts, such as Easter, and Pentecost.
