The Greek letters have a deep and ancient meaning.
It is common in Christian art to find two Greek letters: the alpha (Α) and omega (Ω). These two letters have an ancient history in Christianity and are rooted in the book of Revelation, where God says, “‘I am the Alpha and the Omega,’ says the Lord God, who is and who was and who is to come, the Almighty” (Revelation 1:8). Later on in the same book of the New Testament Jesus assigns that phrase to himself saying, “I am the Alpha and the Omega, the beginning and the end. As a result, from the very beginning of Christianity the first and last letters of the Greek alphabet were used to affirm Jesus Christ’s divinity. [More]
