Book IV.
------------------------
Argument--Passing to the second part of his work, that which treats of expression, the author premises that it is no part of his intention to write a treatise on the laws of rhetoric. These can be learned elsewhere, and ought not to be neglected, being indeed specially necessary for the Christian teacher, whom it behoves to excel in eloquence and power of speech. After detailing with much care and minuteness the various qualities of an orator, he recommends the authors of the Holy Scriptures as the best models of eloquence, far excelling all others in the combination of eloquence with wisdom. He points out that perspicuity is the most essential quality of style, and ought to be cultivated with especial care by the teacher, as it is the main requisite for instruction, although other qualities are required for delighting and persuading the hearer. All these gifts are to be sought in earnest prayer from God, though we are not to forget to be zealous and diligent in study. He shows that there are three species of style, the subdued, the elegant, and the majestic; the first serving for instruction, the second for praise, and the third for exhortation: and of each of these he gives examples, selected both from scripture and from early teachers of the church, Cyprian and Ambrose. He shows that these various styles may be mingled, and when and for what purposes they are mingled; and that they all have the same end in view, to bring home the truth to the hearer, so that he may understand it, hear it with gladness, and practise it in his life. Finally, he exhorts the Christian teacher himself, pointing out the dignity and responsibility of the office he holds to lead a life in harmony with his own teaching, and to show a good example to all.
Chapter 1.--This Work Not Intended as a Treatise on Rhetoric.
1. This work of mine, which is entitled On Christian Doctrine, was at the commencement divided into two parts. For, after a preface, in which I answered by anticipation those who were likely to take exception to the work, I said, "There are two things on which all interpretation of Scripture depends: the mode of ascertaining the proper meaning, and the mode of making known the meaning when it is ascertained. I shall treat first of the mode of ascertaining, next of the mode of making known, the meaning." [1935] As, then, I have already said a great deal about the mode of ascertaining the meaning, and have given three books to this one part of the subject, I shall only say a few things about the mode of making known the meaning, in order if possible to bring them all within the compass of one book, and so finish the whole work in four books.
2. In the first place, then, I wish by this preamble to put a stop to the expectations of readers who may think that I am about to lay down rules of rhetoric such as I have learnt, and taught too, in the secular schools, and to warn them that they need not look for any such from me. Not that I think such rules of no use, but that whatever use they have is to be learnt elsewhere; and if any good man should happen to have leisure for learning them, he is not to ask me to teach them either in this work or any other.

Chapter 2.--It is Lawful for a Christian Teacher to Use the Art of Rhetoric.
3. Now, the art of rhetoric being available for the enforcing either of truth or falsehood, who will dare to say that truth in the person of its defenders is to take its stand unarmed against falsehood? For example, that those who are trying to persuade men of what is false are to know how to introduce their subject, so as to put the hearer into a friendly, or attentive, or teachable frame of mind, while the defenders of the truth shall be ignorant of that art? That the former are to tell their falsehoods briefly, clearly, and plausibly, while the latter shall tell the truth in such a way that it is tedious to listen to, hard to understand, and, in fine, not easy to believe it? That the former are to oppose the truth and defend falshood with sophistical arguments, while the latter shall be unable either to defend what it true, or to refute what is false? That the former, while imbuing the minds of their hearers with erroneous opinions, are by their power of speech to awe, to melt, to enliven, and to rouse them, while the latter shall in defence of the truth be sluggish, and frigid, and somnolent? Who is such a fool as to think this wisdom? Since, then, the faculty of eloquence is available for both sides, and is of very great service in the enforcing either of wrong or right, why do not good men study to engage it on the side of truth, when bad men use it to obtain the triumph of wicked and worthless causes, and to further injustice and error?
