From St. Augustine's Homily

"The deeds of men are only discerned by the root of charity. For many things may be done that have a good appearance, and yet proceed not from the root of charity. For thorns also have flowers; some actions truly seem rough, seem savage; howbeit they are done for discipline at the bidding of charity. Once for all, then, a short precept is given thee: Love, and do what thou wilt: whether thou hold thy peace, through love hold thy peace; whether thou cry out, through love cry out; whether thou correct, through love correct; whether thou spare, through love do thou spare: let the root of love be within, of this root can nothing spring but what is good."
