In that age, however, although fasting upon the Lord's day was not usually practised, it was not so great an offence to the Church when, in any similar emergency to that in which Paul was at Troas, men did not attend to the refreshment of the body throughout the whole of the Lord's day until midnight, or even until the dawn of the following morning. But now, since heretics, and especially these most impious Manichaeans, have begun not to observe an occasional fast upon the Lord's day, when constrained by circumstances, but to prescribe such fasting as a duty binding by sacred and solemn institution, and this practice of theirs has become well known to Christian communities; even were such an emergency arising as that which the apostle experienced, I verily think that what he then did should not now be done, lest the harm done by the offence given should be greater than the good received from the words spoken. Whatever necessity may arise, or good reason, compelling a Christian to fast on the Lord's day,--as we find, e.g., in the Acts of the Apostles, that in peril of shipwreck they fasted on board of the ship in which the apostle was for fourteen days successively, within which the Lord's day came round twice, ¹ --we ought to have no hesitation in believing that the Lord's day is not to be placed among the days of voluntary fasting, except in the case of one vowing to fast continuously for a period longer than a week.
