On Interior Humility
I would not affect either folly or wisdom; for just as humility deters me from pretending to be wise, so simplicity and straightforwardness deter me from pretending to be foolish; and just as vanity is opposed to humility, so all affectation 153 and pretence are opposed to honesty and simplicity. If certain eminent servants of God have feigned folly in order to be despised by the world, we may marvel, but not imitate them; for they had special and extraordinary reasons for doing extraordinary things, and cannot be used as a rule for such as we are. When David 7070 2 Sam. vi. 14. danced more than was customary before the Ark of the Covenant, it was not with the intention of affecting folly, but simply as expressing the unbounded and extraordinary gladness of his heart. Michal his wife reproached him with his actions as folly, but he did not mind being “vile and base in his own sight,” but declared himself willing to be despised for God’s Sake. And so, if you should be despised for acts of genuine devotion, humility will enable you to rejoice in so blessed a contempt, the cause of which does not lie with you.
