Bill, with Shrove Tuesday now on the horizon, I’d like to ask you a question about the history of the forty-day Lenten fast. Here are some statements which we commonly see, both in books and on the internet (including here at CAF). Which of these statements are known to be true, which are known to be false, and which are uncertain, pending confirmation/rejection?
• Prior to the reign of Constantine, the fast never lasted longer than two or three days at the most, commemorating what was believed to be the exact duration of Christ’s time in the tomb.
• Athanasius had never even heard of a forty-day Lenten fast until he came to Rome, which means it must have been a practice that began in the West, not in the East.
• It may even have been Constantine himself who liked the idea of the forty-day fast, which he had heard about as a local custom somewhere in the West. He then put pressure on both Sylvester and Athanasius to introduce it as standard Church practice.
• The forty-day Lenten Fast was introduced either by the Council of Nicea or (more likely) a few years later, in the late 320s or early 330s.
• In its original form, the duration was exactly forty days, beginning on Quadragesima Sunday and ending on Holy Thursday.
• Athanasius, the bishop of Alexandria, was put in charge of determining the exact dates in each year, because that depended on astronomical calculations and Alexandria was the place that had the best astronomers.
• After a few years it was noticed that some communities were observing the Lenten fast on weekdays only, allowing themselves Sundays off. This would explain why, later in the same century, the Church added four extra days at the beginning of Lent, from Ash Wednesday to Saturday, to bring the duration of the fast back to the full forty days.
Summarizing, in accordance with this hypothesis, the 47-day period beginning on Ash Wednesday and ending on Easter Sunday can be split up into three parts:
(1) From Ash Wednesday to Saturday, a later addition to the original Lent … … … … … 4 days
(2) From Quadragesima Sunday to Holy Thursday, Pope Sylvester’s original Lent … … 40 days
(3) From Good Friday to Easter Sunday, the Easter Triduum … … … … … … … … 3 days
Total … … … … … 47 days
