How the rus became an orthodox state

The Russian Orthodox Church (Russian: Русская Православная Церковь) is traditionally said to have been founded by Andrew the Apostle, who is thought to have visited Scythia and Greek colonies along the northern coast of the Black Sea. According to one of the legends, St. Andrew reached the future location of Kiev and foretold the foundation of a great Christian city.[1][2] The spot where he reportedly erected a cross is now marked by St. Andrew's Cathedral
