The man who is filled with the Holy Spirit speaks in different languages. These different languages are different ways of witnessing to Christ, such as humility, poverty, patience and obedience; we speak in those languages when we reveal in ourselves these virtues to others. Actions speak louder than words; let your words teach and your actions speak. We are full of words but empty of actions, and therefore are cursed by the Lord, since he himself cursed the fig tree when he found no fruit but only leaves. Gregory says: “A law is laid upon the preacher to practice what he preaches.” It is useless for a man to flaunt his knowledge of the law if he undermines its teaching by his actions.
