Great as the errors which we have pointed out undoubtedly are, the book itself is of real value, and encourages us to form sanguine hopes of the future services of its author to historical science, and ultimately to religion. We are hardly just in complaining of Protestant writers who fail to do justice to the Church. There are not very many amongst ourselves who take the trouble to ascertain her real character as a visible institution, or to know how her nature has been shown in her history. We know the doctrine which she teaches; we are familiar with the outlines of her discipline. We know that sanctity is one of her marks, and that beneficence has characterised her influence. In a general way we are confident that historical accusations are as false as dogmatic attacks, and most of us have some notion of the way in which the current imputations are to be met. But as to her principles of action in many important things, how they have varied in course of time, what changes have been effected by circumstances, and what rules have never been broken,--few are at the pains to inquire. As adversaries imagine that in exposing a Catholic they strike Catholicism, and that the defects of the men are imperfections in the institution and a proof that it is not divine, so we grow accustomed to confound in our defence that which is defective and that which is indefectible, and to discover in the Church merits as self-contradictory as are the accusations of her different foes. At one moment we are told that Catholicism teaches contempt, and therefore neglect of wealth; at another, that it is false to say that the Church does not promote temporal prosperity. If a great point is made against persecution, it will be denied that she is intolerant, whilst at another time it will be argued that heresy and unbelief deserve to be punished.
