Abba Agathon said, “No passion is worse than an uncontrolled tongue, for it is the mother of all passions.”
All I can say about this one are the words of Saint James.
So the tongue is a little member and boasts of great things. How great a fire is set ablaze by a small fire! And the tongue is a fire. The tongue is an unrighteous world among our members, staining the whole body, setting on fire the cycle of nature and set on fire by hell.
