6. Therefore the saints of the Lord loved to keep silence, because they knew that a man’s voice is often the utterance of sin, and a man’s speech is the beginning of human error. Lastly, the Saint of the Lord said: “I said, I will take heed to my ways, that I offend not in my tongue.” Ps. xxxix. [xxxviii.] 1. For he knew and had read that it was a mark of the divine protection for a man to be hid from the scourge of his own tongue, Job v. 21. and the witness of his own conscience. We are chastised by the silent reproaches of our thoughts, and by the judgment of conscience. We are chastised also by the lash of our own voice, when we say things whereby our soul is mortally injured, and our mind is sorely wounded. But who is there that has his heart clean from the impurities of sin, and does not offend in his tongue? And so, as he saw there was no one who could keep his mouth free from evil speaking, he laid upon himself the law of innocency by a rule of silence, with a view to avoiding by silence that fault which he could with difficulty escape in speaking.
