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.
Jerome
Some think that the faith that is compared to a grain of mustard-seed is a little faith, whereas the Apostle says, If I shall have such faith that I could remove mountains. (1 Cor. 13:2.) The faith therefore which is compared to a grain of mustard-seed is a great faith.
