The Ascetical Homilies of Saint Isaac the Syrian - Homily Four Part III

In this section of the 4th Homily Isaac warns: "Do not take it upon yourself to teach others while still in ill health; rather consider yourself ignorant and always a novice - preferring humility, holiness and purity to all things. Guard against becoming mere vendors of words and arm yourself with the weapons of tears, fasting and the study of scripture and the Fathers.
