A picture of life in the fifth century must needs contain much which will be painful to any reader, and which the young and innocent will do well to leave altogether unread. It has to represent a very hideous, though a very great, age; one of those critical and cardinal eras in the history of the human race, in which virtues and vices manifest themselves side by side&mdash;even, at times, in the same person&mdash;with the most startling openness and power. One who writes of such an era labours under a troublesome disadvantage. He dare not tell how evil people were; he will not be believed if he tells how good they were. In the present case that disadvantage is doubled; for while the sins of the Church, however heinous, were still such as admit of being expressed in words, the sins of the heathen world, against which she fought, were utterly indescribable; and the Christian apologist is thus compelled, for the sake of decency, to state the Church&rsquo;s case far more weakly than the facts deserve.<br />Not, be it ever remembered, that the slightest suspicion of immorality attaches either to the heroine of this book, or to the leading philosophers of her school, for several centuries. Howsoever base and profligate their disciples, or the Manichees, may have been, the great Neo-Platonists were, as Manes himself was, persons of the most rigid and ascetic virtue.<br />For a time had arrived, in which no teacher who did not put forth the most lofty pretensions to righteousness could expect a hearing. That Divine Word, who is &lsquo;The Light who lighteth every man which cometh into the world,&rsquo; had awakened in the heart of mankind a moral craving never before felt in any strength, except by a few isolated philosophers or prophets.
