This finely painted icon depicts the Three Holy Hierarchs of Orthodox Christianity - Gregory the Theologian (known as Gregory of Nazianzus), Basil the Great (known as Basil of Caesarea), and John Chrysostom. They were highly influential bishops of the early Church who played pivotal roles in shaping Christian theology. In Eastern Christianity, they are also known as the Three Great Hierarchs and Ecumenical Teachers, while in Roman Catholicism, the three are honored as Doctors of the Church. The three are venerated as saints in Eastern Orthodoxy, Catholicism, Anglicanism, and other Christian churches.
