Pride seeks after honours and is grieved when it is despised; humility is averse to being treated well and rejoices in contempt, which it knows that it deserves, and its own uprightness renders it desirous that justice should be done.
Pride never has what it wants, for whatever it possesses, or has given to it, it considers that it deserves still more; while humility always thinks it has more than enough, for it believes that it is unworthy to walk the earth, and that hell itself is not sufficient punishment for its sins.
Pride can live in peace with no one, not even with itself, while humility agrees with all men, for it abases itself before everyone and bears patiently with them, believing with all its heart that they are better than itself.
Pride finds it insupportable to submit to others, whether to God, or a mortal creature, but humility gives way and bows down, so that it is able to pass through the "narrow gate" of obeying the will of God and man.
