THE writer of this work proposes to present in three volumes, in English, an outline of a three year course of Dogmatic Theology, such as is offered to students for the priesthood in Catholic Seminaries. No attempt is made to give more than the merest outline; but it is hoped that it will satisfy the needs of some who are not professional students, especially by showing the nature of the questions dealt with in each Treatise, and their proportionate importance, as indicated by the space allowed to them.
