IT will be scarcely necessary to recommend a work by Mgr. Leroy to those who have known what his record is as a prelate of action, a man of learning, an effective wielder of the pen. In presenting to them and others an English version of his book Credo we can offer the assurance that it is marked by a threefold character conformable to that which we have just ascribed to the author. It is a brief, pointed, business-like, but by no means heartless, setting forth of the entire field of Catholic Christian belief; a treatment of theological problems and practical duties in a form well calculated to meet the wants and appeal to the judgment of the busy man or woman of the world as we know it. Its merits of matter and form have been fully recreated in the version now offered to the public. So large is the field covered by the revered author and so precise are his details that some slight modifications have been deemed advisable in order to fit the work perfectly to its new circle of readers. A few particularities have been omitted; a few brief phrases have been expanded in one or two passages (as that explaining the Sixth Precept of the Church), and care has been taken to conform the language to the latest official declarations. It is hoped that in its new garb the work of the eminent French missioner and prelate will continue among Catholics and non-Catholics of the English-speaking world the career of usefulness for which it has been happily distinguished.
