In 1867, Dr. M. Scheeben anticipated our subject in a small brochure of 31 pages, entitled "Die Heiligkeit der Kirche im Neunzehnten Jahrhundert." Even then, it is true, this mark of its divine character was manifest in the Church of the nineteenth century, but the material available in proof of it was, of course, far less rich and abundant then than it is to-day. Hence the present work can hardly be thought superfluous. In 1901, the Congregation of Rites published a catalogue of all the processes of beatification and canonization in progress that year. This publication is the chief source for the names of those persons in the nineteenth century to whose holiness the Church has been petitioned to give official recognition. Since then many new processes have been introduced. Due notice has been given of these from time to time in the "Acta Apostolicae Sedis," and "Analecta Ecclesiastica" and in other periodicals. Included in this work are John Neumann, Anthony Claret, the Cure of Ars, Joseph Cafasso, Clement Hofbauer, Caspar del Bafalo, Francis Libermann, John Bosco, Pierre Eymard, Philippine Ducheesne, Catherine Laboure, Bernadette Soubirous, Elizabeth Seton, Teresa of the Child Jesus, Anna Catherine Emmerich, Dominic Savio, Anna Maria Taigi, and many others. It is good to get a look at the lives of these people, when many of their canonization causes had barely begun and some have not yet been completed today.
