”Mildness is a virtue, in which principally consists nobility of soul. And for this reason it is that lovers of the world often fail in mildness, because they are not possessed of that nobility, or only in a very scanty and imperfect degree. If they are not the first to use insulting and uncourteous terms, at least when they are attacked by others they resent it with the utmost indignation, giving in return language doubly abusive, and thus showing by their vengeance that they have an ignoble disposition. The servants of God, on the other hand, whether provoked by word or work, by keeping themselves tranquil and peaceful, evince a perfect nobleness of soul.”

-Saint Thomas Aquinas, Doctor of the Church
