His father, Carion the Egyptian, forsook his family to become a monk, taking Zacharias with him. Though very young, Zacharias manifested gifts of grace rarely seen among the elders of Sketis. Abba Moses once asked him, 'What does it mean to be a monk?', to which Zacharias replied by taking off his hat and treading it underfoot, saying 'If a man be not so broken, he cannot be a monk.' After shining as a great light among the holy monks of Scetis, he reposed at a young age.
