But if any cleric or deacon, or a man in any orders, who in the world was a layman with sons and daughters, after his profession has again known his wife, and again begotten a son of her, let him know that he has committed adultery, and has sinned no less than if he had been a cleric from his youth, and had sinned with a strange maiden, since he sinned after his vow, after he consecrated himself to the Lord, and has made his vow void. Therefore let him likewise do penance seven years on bread and water.’’
cf. Paen. Venniani 27
