Nicene and Post-Nicene Fathers, Vol. III:
Moral Treatises of St. Augustin: Section 10

10. This affection the Martyrs of Christ contending for the truth did overcome: and it is no marvel that they despised that whereof they should, when death was overpast, have no feeling, when they could not by those tortures, which while alive they did feel, be overcome. God was able, no doubt, (even as He permitted not the lion when it had slain the Prophet, to touch his body further, and of a slayer made it to be a keeper): He was able, I say, to have kept the slain bodies of His own from the dogs to which they had been flung; He was able in innumerable ways to have deterred the rage of the men themselves, that to burn the carcases, to scatter the ashes, they should not dare: but it was fit that this experience also should not be lacking to manifold variety of temptations, lest the fortitude of confession which would not for the saving of the life of the body give way to the savageness of persecution, should be tremblingly anxious for the honor of a sepulchre: in a word, lest faith of resurrection should dread the consuming of the body. It was fit then, that even these things should be permitted, in order that, even after these examples of so great horror, the Martyrs, fervent in confession of Christ, should become witnesses of this truth also, in which they had learned that they by whom their bodies should be slain had after that no more that they could do. 2734 Because, whatever they should do to dead bodies, they would after all do nothing, seeing that in flesh devoid of all life, neither was it possible for him to feel aught who had thence departed, nor for Him to lose aught thereof, Who created the same. But while these things were doing to the bodies of the slain, albeit the Martyrs, not frightened by them, did with great fortitude suffer, yet among the brethren was there exceeding sorrow, because there was given them no means of paying the last honors to the remains of the Saints, neither secretly to withdraw any part thereof, (as the same history testifies,) did the watchings of cruel sentinels permit. So, while those which had been slain, in the tearing asunder of their limbs, in the burning up of their bones, in the dispersion of their ashes, could feel no misery; yet these who had nothing of them that they could bury, did suffer torture of exceeding grief in pitying them; because what those did in no sort feel, these in some sort did feel for them, and where was henceforth for those no more suffering, yet these did in woful compassion suffer for them.
