My question is this: Where have the US bishops defined what fasting is for American Catholics during Lent? The reason why I ask is that a friend claims that during the fast days of Ash Wednesday and Good Friday, we are not only restricted to eating 1 full meal and 2 smaller snacks, but that we must also not drink any alcohol and other "non-water" beverages.
This didn’t seem right, because what I had always remembered was that fasting was simply the meal restriction. Although I believe that the spirit of Lent will prevent me from drinking alcohol on Ash Wednesday or Good Friday, I just wanted a clarification about the law.
I’ve looked everywhere, and I can’t seem to find a definition of lenten fasting. Help! Thanks in advance.
The U.S. bishops have not created particular law for the United States regarding the form of fasting to be observed here, which means that the Church’s universal law on the subject will prevail. That law is found in the 1966 apostolic constitution Paenitemini, where Pope Paul VI provided:
The law of fasting allows only one full meal a day, but does not prohibit taking some food in the morning and evening, observing—as far as quantity and quality are concerned—approved local custom (norm III:2).
That’s it.
Beyond that, we have to fall back on the common and constant opinion of learned persons as to what it means.
When we do that, it is immediately clear that in interpreting the Church’s laws regarding fasting the terms "meal" and "food" are understood as being food rather than beverages. If you go look in old moral theologies, they invariably talk about the fact that you can drink things–including things other than water–on days of fasting.
Some moralists have considered alcoholic beverages contrary to the spirit of the day, but they don’t consider beverages other than water to be contrary to the spirit. Examples they commonly cite of beverages that are okay to have on fasting days are milk and fruit juices and coffee with cream, all of which contain calories.
Beverages just are not included under the law of fasting.
This means that, if I wanted, I could drink can after can of low-carb protein shakes on Ash Wednesday and Good Friday and consume 3500 calories of them and still be within the letter of the law.
I would not, however, be within the spirit of the law, which is to encourage moderate hunger as a form of spiritual discipline. If I use calorie-laden beverages (or hunger suppressants) to get around that then I am violating the spirit though not the letter of the law.
As a result, to comply with the spirit of the law, on days of fast I drink whatever I normally would drink but I don’t start chugging extra calories in fluid form. I keep my beverage consumption (mainly zero-calorie Diet 7-Up, since it’s made with Splenda rather than Aspartame) the same and lower the amount of food I eat.
