Rev. Father Martin von Cochem, of the Capuchin Order, wrote many erudite and edifying spiritual treatises. None of these, however, is equal in learning and in practical usefulness to his Explanation of the Holy Mass, which is compiled from the teaching of the holy Catholic Church, of the early fathers, of contemporary theologians and spiritual writers. It is, moreover, written in an agreeable and impressive manner, and the perusal of it cannot fail to give the reader a better acquaintance with the nature of the Mass, to inflame him with devotion for it, and greatly to increase his desire to lose no opportunity of celebrating the Holy Sacrifice or assisting at it, as the case may be.
