Meaning of Alpha – Symbols Dictionary
Alpha symbolizes the beginning, as it is the name of the first Greek letter of the classical Greek alphabet (alpha). Its origin, however, is Hebrew. It comes from álefe, which is the name of the first letter of the Hebrew alphabet.
The alphabet, which would have been created by Cadmus, a legendary Phoenician hero, would have alpha as the first letter because it is also the first letter of the Phoenician alphabet.
Alpha and Omega
Together with Omega (last letter of the Greek alphabet), it represents God in Christianity.
“I am the Alpha and the Omega,” says the Lord God, “the one who is, the one who was, and the one who is to come, the Almighty.” (Revelation 1:8)
It should be noted that the modern expression “from A to Z” has the sense of something complete or done in a detailed and careful way.
