From the Rule of St. Benedict:
Let us do what the Prophet says:
"I said, 'I will guard my ways,
that I may not sin with my tongue.
I have set a guard to my mouth.'
I was mute and was humbled,
and kept silence even from good things" (Ps. 38:2-3).
Here the Prophet shows
that if the spirit of silence ought to lead us at times
to refrain even from good speech,
so much the more ought the punishment for sin
make us avoid evil words.
Therefore, since the spirit of silence is so important,
permission to speak should rarely be granted
even to perfect disciples,
even though it be for good, holy edifying conversation;
for it is written,
"In much speaking you will not escape sin" (Prov. 10:19),
and in another place,
"Death and life are in the power of the tongue" (Prov. 18:21).
And so will I also not say anything further about the incident.
