Matthew 17:19
Douay-Rheims
Jesus said to them: Because of your unbelief. For, amen I say to you, if you have faith as a grain of mustard seed, you shall say to this mountain, Remove from hence hither, and it shall remove; and nothing shall be impossible to you.
Origen
If then we shall ever be required to be employed in the healing of those who are suffering any thing of this sort, we shall not adjure them, nor ask them questions, nor even speak, as though the unclean spirit could hear us, but by our fasting and our prayers drive away the evil spirits.
