Before we proceed to give a special account of the martyrs who were put to death in this persecution, we deem it necessary to call the attention of the reader to the following points: 1. That after A. D. 300, that is, in the beginning of this century, many errors began to arise among some of those who were called Christians, especially among those who belonged under the Roman dominion. Yea, they went so far as to resort to carnal weapons (which, however, had already previously been done by some); through which the defenseless and meek lambs of Christ suffered not a little distress, fear, and sorrow.
That, besides the martyrs of the true faith, some of the aforesaid class suffered themselves to be killed for their opinions; whereby the death and the glorious martyrdom of the true Christian believers were not a little obscured.
That, in order to distinguish these from the former, we have exerted our utmost diligence, so that as far as we know, there are not found among the martyrs of whom we have given, or may yet give, an account, any who can be shown to have been guilty of gross errors, much less of the shedding of blood. At least we have not been able to detect it in any of them, and hence in accordance with the spirit of love, we must judge and believe the best of them.
As this persecution under Diocletian and Maximian was not only very severe, but also of long duration, we have deemed it well to present its years separately in consecutive order, and to show what the pious martyrs suffered in each year, steadfastly confessing with their blood the truth of God.
