Many times, the laity of the Church are called the sheep, while the priests are referred to as shepherds.
Now, yesterday I took my kids to a pumpkin patch where they have a little "petting" zoo, and there, I was almost bitten by a pig. I thought it hilarious at the time.
But a thought entered my mind. Even farm animals will bite, kick, and ram you if you abuse them. I suppose the same could be said about an abused herd of sheep?
