Stachys the Apostle (Greek: Στάχυς, "ear-spike"; died 54) was the second bishop of Byzantium, from 38 AD to 54 AD according to tradition.
Stachys is mentioned just one time in the New Testament as a person loved by Paul the Apostle (Romans 16:9).[2] Other than that, all information regarding him comes from tradition. He seemed to be closely connected to Andrew the Apostle and Paul the Apostle. 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,[3] a position he held for sixteen years.[4]
This See would later develop into the Patriarchate of Constantinople, having Apostle Andrew as its Patron Saint. Stachys founded a church at Argyropouli, and many people gathered there to hear him preach.[5]
