City of God: Chapter 10

Chapter 10.—That the Martyrs Who Obtain Many Miracles in Order that the True God May Be Worshipped, are Worthy of Much Greater Honor Than the Demons, Who Do Some Marvels that They Themselves May Be Supposed to Be God.

Here perhaps our adversaries will say that their gods also have done some wonderful things, if now they begin to compare their gods to our dead men.  Or will they also say that they have gods taken from among dead men, such as Hercules, Romulus, and many others whom they fancy to have been received into the number of the gods?  But our martyrs are not our gods; for we know that the martyrs and we have both but one God, and that the same.  Nor yet are the miracles which they maintain to have been done by means of their temples at all comparable to those which are done by the tombs of our martyrs.  If they seem similar, their gods have been defeated by our martyrs as p. 492 Pharaoh’s magi were by Moses.  In reality, the demons wrought these marvels with the same impure pride with which they aspired to be the gods of the nations; but the martyrs do these wonders, or rather God does them while they pray and assist, in order that an impulse may be given to the faith by which we believe that they are not our gods, but have, together with ourselves, one God.  In fine, they built temples to these gods of theirs, and set up altars, and ordained priests, and appointed sacrifices; but to our martyrs we build, not temples as if they were gods, but monuments as to dead men whose spirits live with God.  Neither do we erect altars at these monuments that we may sacrifice to the martyrs, but to the one God of the martyrs and of ourselves; and in this sacrifice they are named in their own place and rank as men of God who conquered the world by confessing Him, but they are not invoked by the sacrificing priest.  For it is to God, not to them, he sacrifices, though he sacrifices at their monument; for he is God’s priest, not theirs.  The sacrifice itself, too, is the body of Christ, which is not offered to them, because they themselves are this body.  Which then can more readily be believed to work miracles?  They who wish themselves to be reckoned gods by those on whom they work miracles, or those whose sole object in working any miracle is to induce faith in God, and in Christ also as God?  They who wished to turn even their crimes into sacred rites, or those who are unwilling that even their own praises be consecrated, and seek that everything for which they are justly praised be ascribed to the glory of Him in whom they are praised?  For in the Lord their souls are praised.  Let us therefore believe those who both speak the truth and work wonders.  For by speaking the truth they suffered, and so won the power of working wonders.  And the leading truth they professed is that Christ rose from the dead, and first showed in His own flesh the immortality of the resurrection which He promised should be ours, either in the beginning of the world to come, or in the end of this world.
