Transubstantiation

As we have been working our way through John 6 at Mass these past few weeks, this passage from the Omnivore's Dilemma caught my attention.  "[The grass farmer] reached down deep where his pigs were happily rooting and brought a  handful of fresh compost right up to my nose.  What had been cow manure and woodchips just a few weeks before now smelled as sweet and warm as the forest floor in summertime, a miracle of transubstantiation."
