It is impossible, from the duty of God to men, that a man, hiding his evil teaching, and only showing the good, saying that he conforms to God and the Church, should do miracles so as to instil insensibly a false and subtle doctrine. This cannot happen.
And still less, that God, who knows the heart, should perform miracles in favour of such a one.

The three marks of religion: perpetuity, a good life, miracles. They destroy perpetuity by their doctrine of probability; a good life by their morals; miracles by destroying either their truth or the conclusions to be drawn from them.
If we believe them, the Church will have nothing to do with perpetuity, holiness, and miracles. The heretics deny them, or deny the conclusions to be drawn from them; they do the same. But one would need to have no sincerity in order to deny them, or again to lose one's senses in order to deny the conclusions to be drawn from them.
Nobody has ever suffered martyrdom for the miracles which he says he has seen; for the folly of men goes perhaps to the length of martyrdom, for those which the Turks believe by tradition, but not for those which they have seen.

The heretics have always attacked these three marks, which they have not.

First objection: "An angel from heaven.[349] We must not judge of truth by miracles, but of miracles by truth. Therefore the miracles are useless."
