On Christian Doctrine

by Augustine of Hippo

For a sign is a thing which, over and above the impression it makes on the senses, causes something else to come into the mind as a consequence of itself: as when we see a footprint, we conclude that an animal whose footprint this is has passed by; and when we see smoke, we know that there is fire beneath; and when we hear the voice of a living man, we think of the feeling in his mind; and when the trumpet sounds, soldiers know that they are to advance or retreat, or do whatever else the state of the battle requires.

Conventional signs, on the other hand, are those which living beings mutually exchange for the purpose of showing, as well as they can, the feelings of their minds, or their perceptions, or their thoughts.

it is necessary that we should be led by the fear of God to seek the knowledge of His will, what He commands us to desire and what to avoid.

it is necessary to have our hearts subdued by piety, and not to run in the face of Holy Scripture, whether when understood it strikes at some of our sins, or, when not understood, we feel as if we could be wiser and give better commands ourselves.

We must rather think and believe that whatever is there written, even though it be hidden, is better and truer than anything we could devise by our own wisdom.

Now the whole canon of Scripture on which we say this judgment is to be exercised, is contained in the following books:—Five books of Moses, that is, Genesis, Exodus, Leviticus, Numbers, Deuteronomy; one book of Joshua the son of Nun; one of Judges; one short book called Ruth, which seems rather to belong to the beginning of Kings; next, four books of Kings, and two of Chronicles—these last not following one another, but running parallel, so to speak, and going over the same ground. The books now mentioned are history, which contains a connected narrative of the times, and follows the order of the events. There are other books which seem to follow no regular order, and are connected neither with the order of the preceding books nor with one another, such as Job, and Tobias, and Esther, and Judith, and the two books of Maccabees, and the two of Ezra,69 which last look more like a sequel to the continuous regular history which terminates with the books of Kings and Chronicles. Next are the Prophets, in which there is one book of the Psalms of David; and three books of Solomon, viz., Proverbs, Song of Songs, and Ecclesiastes. For two books, one called Wisdom and the other Ecclesiasticus, are ascribed to Solomon from a certain resemblance of style, but the most likely opinion is that they were written by Jesus the son of Sirach.70 Still they are to be reckoned among the prophetical books, since they have attained recognition as being authoritative. The remainder are the books ...

That of the New Testament, again, is contained within the following:—Four books of the Gospel, according to Matthew, according to Mark, according to Luke, according to John; fourteen epistles of the Apostle Paul—one to the Romans, two to the Corinthians, one to the Galatians, to the Ephesians, to the Philippians, two to the Thessalonians, one to the Colossians, two to Timothy, one to Titus, to Philemon, to the Hebrews: two of Peter; three of John; one of Jude; and one of James; one book of the Acts of the Apostles; and one of the Revelation of John.

to know these books, if not yet with the understanding, still to read them so as to commit them to memory, or at least so as not to remain wholly ignorant of them.
