St. Augustine
the Rule

Chapter III

3.1 Subdue [6] the flesh, so far as your health permits, by fasting and abstinence from food and drink. However, when someone is unable to fast, he should still take no food outside mealtimes unless he is ill.

3.2 When you come to table, listen until you leave to what is the custom to read, without disturbance or strife. Let not your mouths alone take nourishment but let your hearts too hunger for the words of God.

3.3 If those in more delicate health from their former way of life are treated differently in the matter of food, this should not be a source of annoyance to the others or appear unjust in the eyes of those who owe their stronger health to different habits of life. Nor should the healthier brothers deem them more fortunate for having food which they do not have, but rather consider themselves fortunate for having the good health which the others do not enjoy.

3.4 And if something in the way of food, clothing, and bedding is given to those coming to the monastery from a more genteel way of life, which is not given to those who are stronger, and therefore happier, then these latter ought to consider how far these others have come in passing from their life in the world down to this life of ours, though they have been unable to reach the level of frugality common to the stronger brothers. Nor should all want to receive what they see given in larger measure to the few, not as a token of honour, but as a help to support them in their weakness. This would give rise to a deplorable disorder - that in the monastery, where the rich are coming to bear as much hardship as they can, the poor are turning to a more genteel way of life.

3.5 And just as the sick must take less food to avoid discomfort, so too, after their illness, they are to receive the kind of treatment that will quickly restore their strength, even though they come from a life of extreme poverty. Their more recent illness has, as it were, afforded them what accrued to the rich as part of their former way of life. But when they have recovered their former strength, they should go back to their happier way of life which, because their needs are fewer, is all the more in keeping with God's servants. Once in good health, they must not become slaves to the enjoyment of food which was necessary to sustain them in their illness. For it is better to suffer a little want than to have too much [7].
