Ignorance of numbers prevents us from understanding things that are set down in Scripture in a figurative and mystical way.
A candid mind, if I may so speak, cannot but be anxious, for example, to ascertain what is meant by the fact that Moses and Elijah, and our Lord Himself, all fasted for forty days. And except by knowledge of and reflection upon the number, the difficulty of explaining the figure involved in this action cannot be got over. For the number contains ten four times, indicating the knowledge of all things, and that knowledge interwoven with time. For both the diurnal and the annual revolutions are accomplished in periods numbering four each; the diurnal in the hours of the morning, the noontide, the evening, and the night; the annual in the spring, summer, autumn, and winter months. Now while we live in time, we must abstain and fast from all joy in time, for the sake of that eternity in which we wish to live; al though by the passage of time we are taught this very lesson of despising time and seeking eternity.
Further, the number ten signifies the knowledge of the Creator and the creature, for there is a trinity in the Creator; and the number seven indicates the creature, because of the life and the body. For the life consists of three parts, whence also God is to be loved with the whole heart, the whole soul, and the whole mind; and it is very clear that in the body there are four elements of which it is made up. In this number ten, therefore, when it is placed before us in connection with time, that is, when it is taken four times we are admonished to live unstained by, and not partaking of, any delight in time, that is, to fast for forty days. Of this we are admonished by the law personified in Moses, by prophecy personified in Elijah, and by our Lord Himself, who, as if receiving the witness both of the law and the prophets, appeared on the mount between the other two, while His three disciples looked on in amazement. Next, we have to inquire in the same way, how out of the number forty springs the number fifty, which in our religion has no ordinary sacredness attached to it on account of the Pentecost, and how this number taken thrice on account of the three divisions of time, before the law, under the law, and under grace, or perhaps on account of the name of the Father, Son, and Holy Spirit, and the Trinity itself being added over and above, has reference to the mystery of the most Holy Church, and reaches to the number of the one hundred and fifty-three fishes which were taken after the resurrection of our Lord, when the nets were cast out on the right-hand side of the boat. (John 21:11)
And in the same way, many other numbers and combinations of numbers are used in the sacred writings, to convey instruction under a figurative guise, and ignorance of numbers often shuts out the reader from this instruction.
Not a few things, too, are closed against us and obscured by ignorance of Music. One man, for example, has not unskillfully explained some metaphors from the difference between the psaltery and the harp. And it is a question which it is not out of place for learned men to discuss, whether there is any musical law that compels the psaltery of ten chords to have just so many strings; or whether, if there be no such law, the number itself is not on that very account the more to be considered as of sacred significance, either with reference to the ten commandments of the law (and if again any question is raised about that number, we can only refer it to the Creator and the creature), or with reference to the number ten itself as interpreted above. And the number of years the temple was in building, which is mentioned in the gospel (John 2:20) — viz., forty-six — has a certain undefinable musical sound, and when referred to the structure of our Lord’s body, in relation to which the temple was mentioned, compels many heretics to confess that our Lord put on, not a false, but a true and human body. And in several places in the Holy Scriptures we find both numbers and music mentioned with honor.
Coming now to the science of number, it is clear to the dullest apprehension that this was not created by man, but was discovered by investigation. For, though Virgil could, at his own pleasure, make the first syllable of the word Italia long, while the ancients pronounced it short, it is not in any man’s power to determine at his pleasure that three times three are not nine, or do not make a square, or are not the triple of three, nor one and a half times the number six, or that it is not true that they are not the double of any number because odd numbers have no half. Whether, then, numbers are considered in themselves, or as applied to the laws of figures, or of sounds, or of other motions, they have fixed laws which were not made by man, but which the acuteness of ingenious men brought to light.
The man, however, who puts so high a value on these things as to be inclined to boast himself one of the learned, and who does not rather inquire after the source from which those things which he perceives to be true derive their truth, and from which those others which he perceives to be unchangeable also derive their truth and unchangeableness, and who, mounting up from bodily appearances to the mind of man, and finding that it too is changeable (for it is sometimes instructed, at other times uninstructed), although it holds a middle place between the unchangeable truth above it and the changeable things beneath it, does not strive to make all things redound to the praise and love of the one God from whom he knows that all things have their being — the man, I say, who acts in this way may seem to be learned, but wise he cannot in any sense be deemed.
