Alpha and Omega, in Christianity, the first and last letters of the Greek alphabet, used to designate the comprehensiveness of God, implying that God includes all that can be. In the New Testament Revelation to John, the term is used as the self-designation of God and of Christ.

The beginning and the end. In the Greek alphabet, in which the New Testament was written, alpha is the first letter and omega is the last. In the Book of Revelation , God says, “I am Alpha and Omega, the first and the last,” meaning that God remains from the beginning to the end of time.
