Chapter 51: On Brethren Who Go Not Very Far Away
A Brother who is sent out on some business
and is expected to return to the monastery that same day
shall not presume to eat while he is out,
even if he is urgently requested to do so
by any person whomsoever,
unless he has permission from his Abbot.
And if he acts otherwise, let him be excommunicated.
I am thinking the reason Benedict forbade this may have been because he wanted to avoid the appearance of showing favoritism by accepting a meal with this family instead of that.
The other idea that occurs to me is that B didn;t want any of his monks to become dissatisfied with the simple fare of the monastery by remembering the sumptuous meals had elsewhere.
But I really have no idea. These are just my guesses.
