Portiuncula has this quote from Saint Francis:
And all the brothers are to guard against speaking falsely of anyone
and are to avoid verbal disputes. Rather, let them seek to keep silent
whenever God gives them the grace to do so. And they are not to argue
among themselves, nor with others, but they are to strive to respond
with humility, saying, “We are useless servants.” (Luke 17:10)
Rule of 1221, Chapter XI
Who knew that this bit of wise counsel came from Saint Francis? I thought it was just something parents said to keep their kids from squabbling!
