Chapter 62: The priests of the monastery

When ordained a monk must be careful to avoid a spirit of self-importance or pride and he must avoid taking on himself any duties to which the abbot has not assigned him.

(From para. 1 of Ch. 62 of Saint Benedict's Rule, trans. by Patrick Barry OSB, 1997.)

To my ears, St. Benedict is not discouraging a spirit of initiative or service.  He is, more directly, reminding me of the dangers of spiritual pride, and that the ego can insinuate itself into absolutely anything.
