1. Such, then, being the state of the case, and this number being found in all the most approved and ancient copies [of the Apocalypse], and those men who saw John face to face bearing their testimony [to it]; while reason also leads us to conclude that the number of the name of the beast, [if reckoned] according to the Greek mode of calculation by the [value of] the letters contained in it, will amount to six hundred and sixty and six; that is, the number of tens shall be equal to that of the hundreds, and the number of hundreds equal to that of the units (for that number which [expresses] the digit six being adhered to throughout, indicates the recapitulations of that apostasy, taken in its full extent, which occurred at the beginning, during the intermediate periods, and which shall take place at the end),—I do not know how it is that some have erred following the ordinary mode of speech, and have vitiated the middle number in the name, deducting the amount of fifty from it, so that instead of six decads they will have it that there is but one. [I am inclined to think that this occurred through the fault of the copyists, as is wont to happen, since numbers also are expressed by letters; so that the Greek letter which expresses the number sixty was easily expanded into the letter Iota of the Greeks.] Others then received this reading without examination; some in their simplicity, and upon their own responsibility, making use of this number expressing one decad; while some, in their inexperience, have ventured to seek out a name which should contain the erroneous and spurious number. Now, as regards those who have done this in simplicity, and without evil intent, we are at liberty to assume that pardon will be granted them by God. But as for those who, for the sake of vainglory, lay it down for certain that names containing the spurious number are to be accepted, and affirm that this name, hit upon by themselves, is that of him who is to come; such persons shall not come forth without loss, because they have led into error both themselves and those who confided in them. Now, in the first place, it is loss to wander from the truth, and to imagine that as being the case which is not; then again, as there shall be no light punishment [inflicted] upon him who either adds or subtracts anything from the Scripture, under that such a person must necessarily fall. Moreover, another danger, by no means trifling, shall overtake those who falsely presume that they know the name of Antichrist. For if these men assume one [number], when this [Antichrist] shall come having another, they will be easily led away by him, as supposing him not to be the expected one, who must be guarded against.
