Eusebius quotes Origen as saying that Andrew had preached in Asia Minor and in Scythia, along the Black Sea as far as the Volga and Kiev, hence he became a patron saint of Romania and Russia. According to tradition, Saint Andrew founded the See of Byzantium in 38, installing Stachys as bishop (the only bishopric in that neighbourhood before that time had been established at Heraclea). This See would later develop into the Patriarchate of Constantinople, having Apostle Andrew as its Patron Saint.
