This interview with his Eminence Metropolitan Hierotheos of Nafpaktos and Agiou Vlasiou was published in the journal "Καθ' οδόν" by the Community Youth of the Sacred Metropolis of Limassol, and as the reader will see, the questions cover a large part of the Christology of Christmas.
Question: The word Χριστούγεννα (Greek word for "Christmas") means the birth of Christ. We would like you to tell us what was the purpose of the birth of Christ and generally why did the Word of God have to incarnate. Couldn't there have been another way for the salvation of the human race?
Answer: As it is written throughout our biblical-patristic tradition, the purpose of the Incarnation of the Word of God is the theosis of humanity, which means that He who according to His nature is God became man, that we may become gods according to Grace. In one of his discourses, Athanasius the Great analyzes that God sent the Prophets in the Old Testament to speak to His people, but ultimately the issue was how man will be deified and how he will be released from death.
