Andrew, the brother of Simon Peter, was a fisherman of Bethsaida and a disciple of John the Baptist before becoming the first to follow Christ — for which the Greek Church calls him Protokletos, 'the First-Called.' It was Andrew who brought his brother Simon to Jesus, saying: 'We have found the Messiah' (John 1:41).
Tradition, attested in early sources, says Andrew preached the Gospel across Scythia and the lands north of the Black Sea — territories that would become Russia, Ukraine, and Romania, where he is honoured as principal patron. Eusebius records that his mission ended at Patras in Achaea (Greece), where he was crucified by the Roman proconsul Aegeas.
A later tradition, dating from the medieval period, holds that he was crucified on an X-shaped cross at his own request, considering himself unworthy of the same form of death as Christ. This 'saltire' became the cross of St. Andrew, the flag of Scotland.
