1 Soter, bishop of the church of Rome, died after an episcopate of eight years, and was succeeded by Eleutherus, the twelfth from the apostles. In the seventeenth year of the Emperor Antoninus Verus, the persecution of our people was rekindled more fiercely in certain districts on account of an insurrection of the masses in the cities; and judging by the number in a single nation, myriads suffered martyrdom throughout the world. A record of this was written for posterity, and in truth it is worthy of perpetual remembrance.
2. A full account, containing the most reliable information on the subject, is given in our Collection of Martyrdoms, which constitutes a narrative instructive as well as historical. I will repeat here such portions of this account as may be needful for the present purpose.
3. Other writers of history record the victories of war and trophies won from enemies, the skill of generals, and the manly bravery of soldiers, defiled with blood and with innumerable slaughters for the sake of children and country and other possessions.
4. But our narrative of the government of God will record in ineffaceable letters the most peaceful wars waged in behalf of the peace of the soul, and will tell of men doing brave deeds for truth rather than country, and for piety rather than dearest friends. It will hand down to imperishable remembrance the discipline and the much-tried fortitude of the athletes of religion, the trophies won from demons, the victories over invisible enemies, and the crowns placed upon all their heads.
