Let the abbot know that he who has undertaken the government of souls, must prepare himself to render an acount of them. And whatever may be the number of the brethren under his care, let him be certainly assured that on the Day of Judgment he will have to give an account to the Lord of all these souls, as well as of his own. And thus, being ever fearful of the coming judgment of the shepherd concerning the solicitous also of his own. And so, while correcting others by his admonitions, he will be himself cured of his own defects.
Rule of Benedict, Chapter 2
