1909. As will appear from a glance at the subject matter of this volume, we have understood the essence of sacerdotalism to lie in a profound emphasis on priestly authority and on sacramental efficacy. The name is indicative of the system which exalts the office of the priestly hierarchy and the virtue of the rites supposed to depend for their valid administration upon that hierarchy. Contents: Roman Type: principle of ecclesiastical authority; papal absolutism; some features of the sacramental system; outlook for Roman sacerdotalism; Greek, Anglican and Other Types: Greek type, especially as represented in Russia; Anglo-Catholic movement; less important developments of sacerdotalism.
