Fasting the Institution of God.
The scripture is full of places that prove fasting to be not the invention of man but the institution of God, and to have many more profits than one. And that the fasting of one man may do good unto another, our Saviour showeth himself where he saith that some kind of devils cannot be cast out of one man by another “without prayer and fasting.” And therefore I marvel that they take this way against fasting and other bodily penance.
