He was born in Greece and succeeded St Peter of Kiev as Metropolitan of that city. Some of his enemies among his own flock denounced him to the Mongol ruler, saying that he had collected no tribute from his churches to pay to the Mongols. Summoned before the Mongol prince and asked about this, he answered 'Christ our God bought His Church from the unbelievers with His precious Blood. For what do we pay tribute to unbelievers?' Returning home, he governed the Church for twenty-five more years and reposed in peace in 1353.
