The Rule of St. Benedict: Chapter 41
" . . . the Abbot's foresight shall decide on this.
Thus it is that he should adapt and arrange everything
in such a way that souls may be saved
and that the brethren may do their work without just cause for murmuring."
"If you put a stumbling block before one of these little ones who believe in me,
it would be better for you if a great millstone were hung around your neck
and you were thrown into the sea."
