Calvin on Fasting

In my book I quote John Calvin concerning fasting. You can read his complete treatment of this important aspect of a Christian philosophy of food in his book, Institutes of the Christian Religion in Book 4, Chapter 12, Sections 14-21 here: http://www.ccel.org/ccel/calvin/institutes.vi.xiii.html

"Let us, therefore, make some observations on fasting, since very many, not understanding what utility there can be in it, judge it not to be very necessary, while others reject it altogether as superfluous. Where its use is not well known it is easy to fall into superstition." (4.12.15)
