The last man who has come forward with his theory of Christanity is Monsieur Ernest Renan, a Frenchman, a member of the Institute, and a Semitic scholar of some considerable pretensions. He broaches his theory in a book, which he calls 'The Life of Jesus.' He offers it to the world, through that book, as an improvement on the accepted one. We propose here to look at M. Renan's theory, and see whether it has any advantages to offer over that usually taught in churches in America, and which the present writer learned, some _lustra_ ago, while catechized at the chancel veil, and which his children are learning now. It makes the examination easier that M. Renan freely and fully admits the achievements of Christianity. Indeed he glories over them. The beneficence of Christianity, its hallowing and elevating power in the history of the world, its wondrous blessedness among men, the glory it has cast over human life and human aims, the nobleness it has conferred on human character, all these he takes a pride in confessing and appreciating. He will not be a whit behind the stanchest believer in acknowledging the power of these, or in the capacity of prizing these. But he cannot accept the explanation Christianity gives of itself. He proposes another of his own. We may take his theory as the fruit and flower of all 'liberal' thought. Here, at last, is what unbelieving learning and philosophy have to offer in lieu of the divine origin of Christianity. After a good deal of loud boasting, after a large amount of supercilious sneering, we have here the result of that 'profound criticism' and that 'careful scholarship' which have been laboring for years, in Europe, to destroy the supernatural bases of faith. We are justified, from M. Renan's position and character, in taking it for granted, that his book is the best that modern unbelief has to offer, his theory the most satisfactory that the deniers of the divine origin of Christianity can frame.
