They cure the sick by invoking their God, the Creator and the Sovereign
Lord of all things; and the name of Jesus Christ, our Saviour, of whose
Gospel they recite a part. We ourselves have seen several sick persons
delivered from the most formidable maladies, and the cured are too
numerous to be counted."

Tertullian, in his Apology, and in another work, records plainly the
miraculous fall of rain which was obtained from heaven by the prayers
of the Christian soldiers, which saved the army of the Emperor Marcus
Aurelius, which was reduced to the last extremity. He proves the truth
of this fact by the very letter of the emperor. We have also authentic
proofs of this event in the authors and records of paganism itself.
Tertullian, likewise, tells us that the pagans received extraordinary
graces by means of the Christians, some of which he quotes, and he
adds: "How many persons of distinction, without mentioning other people,
have been thus delivered from the devil, and cured of their evils!"

St. Cyprian upbraided an idolater in the following terms, while refuting
him: "The gods whom you adore we exorcise in the name of the true God,
and they are compelled to leave the bodies which they possessed. Oh,
if you chose to see and hear them, when suffering under the power of
our words, as if they were spiritual scourges, and feeling the secret
operation of the Divine Mastery! They howl terrifically, entreat of
us to spare them, declare, in presence of their adorers, whence they
came, and confess a future judgment. Come and be convinced of the truth
of what we say; to be at least moved. Those whom you adore, fear us;
those to whom you pray, entreat of us to spare them; those whom you
revere as sovereigns, are as prisoners in our hands, and tremble as
so many slaves. We interrogate them, and in your presence they declare
what they are; they cannot dissemble the impostures which they make
