The leaders of any given evil heresy also attempt to interpret their writings, but their purpose is to harm their followers and deny that truth which is in accordance with piety, using the words of the Spirit against the Spirit. The words of the gospel of grace are lofty and suitable for mature ears and minds, but these words too our God-bearing Fathers softened in their own mouths, making them appropriate for those of us who are less than perfect, just as mothers devoted to their children chew solid food and render it serviceable and easy to take for babies still at the breast. The moisture in their mothers’ mouth is nourishment for the children, and the thoughts in the hearts of our God-bearing Fathers are suitable food for souls that listen and obey The mouths of evil, disreputable men, however, are full of deadly poison which, when mixed with the words of life, makes even them lethal for careless listeners.
St. Gregory of Palamas, Homily 34, On the Holy Transfiguration of Our Lord and God and Savior Jesus
