What is the highest virtue of all?
The virtue which encompasses all virtues is that of love since on love depend all the Law and the Prophets.
But the basis of all the virtues, the basis on which every good work is built, is the virtue of humility, because every virtue that is not based on humility can lead to self-righteousness and false glory, by which the individual can perish.
Even love itself, which is the greatest virtue, can cause man to perish, if it is not built on humility. In this case it couldn’t actually be called ‘love’, in the exact meaning of the word.
