"Fish was the staple diet of Londoners in the Middle Ages. It was cheap and plentiful, and, even more importantly, meat eating was forbidden on religious grounds on as many as 150 days of each year." Yet, according to 1Timothy 4:1-5, one of the "doctrines of devils" was "commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth. For every creature of God is good, and nothing to be refused, if it be received with thanksgiving."
