Saint Andrew is a Christian preacher, the first among the 12 apostles, personally called by Jesus Christ. He is the brother of Saint Peter and, like him, a fisherman by profession. It is assumed that before becoming a Christian he was a disciple of John the Baptist. According to the distribution of the world (oecumene) that the apostles made among themselves, regarding the places where they would preach, Andrew was given proximity to the Black Sea, including - Asia Minor, Georgia and Scythia. Accordingly, he developed significant missionary activity in lands that later became part of the modern states of Ukraine, Romania and Russia (and is therefore presented as the first preacher of Christianity to visit the Varangians and Slavs), Bulgaria (in the lands that now constitute the Bulgarian Black Sea coast, where Greek colonies were scattered in antiquity) and Turkey (in that part of it that, before the foundation of the Ottoman Empire, constituted the Asia Minor possessions of Byzantium). For this reason, he is considered the founder of the Russian Orthodox Church and is presented as the first Patriarch of Constantinople (the supposed founder of the church in Byzantium and the first bishop of the city).
