Monk Teokletos of Dionisiou A Commentary on Saint Diadochos of Fotiki, Chapters on Knowledge
So much did St. Diadochos love God, that he wept “that he does not love him as much as he wants”, not knowing the great measure of his divine love, because of his humility, the measure of his love. And he spends in such fervent longing after God, that he glorifies himself, and he regards himself ‘as if he were not.'”
