An historical faith in the Savior, in accordance with the view just given, is a faith or belief, that such a man as Jesus Christ, possessing many of the virtuous traits, which his biographers have ascribed to him, appeared in Palestine at the commencement of the Christian era. It is the same species of faith, with which we believe in the existence of the Tituses, Vespasians, and other distinguished historical personages of the same period. This sort of faith, however, which has reference merely to the fact of his existence and to his general character, does not necessarily involve the existence of religion, or even of good morals. A man may be vicious in his character, or without being an immoral man, he may entirely reject Christ in his more important religious aspects and relations, and at the same time believe in him historically. And this was the case, as is well known, with Voltaire, with Diderot, and other distinguished opponents of the Christian system, who readily yielded their assent to the historical matter of fact, that Jesus Christ lived at a certain period of the world, that he was a wise and virtuous man, and that he was put to death by the Jews under the procurate of Pontius Pilate. But a faith, which stops at the historical facts, without recognizing the moral and religious relations and issues involved in them, (and this is always the case with the mere historical faith,) is obviously of no religious value.
