Alpha (Α or α) and omega (Ω or ω) are the first and last letters of the Greek alphabet, and a title of Christ and God in the Book of Revelation. This pair of letters is used as a Christian symbol, and is often combined with the Cross, Chi-rho, or other Christian symbols. Origin The first written record of the phrase "alpha and omega" is from some old manuscripts of the Christian New Testament. The phrase "I am the Alpha and the Omega" (Koiné Greek: "ἐγώ εἰμί τὸ Ἄλφα καὶ τὸ Ὦ"), is an appellation of Jesus and of the Father in the Book of Revelation (verses 1:8, 21:6, and 22:13). The first part of this phrase ("I am the Alpha and the Omega") is first found in Chapter 1 verse 8 ("1:8"), and is found in every manuscript of Revelation that has 1:8. Several later manuscripts repeat "I am the Alpha and the Omega" in 1:11 too, but do not receive support here from most of the oldest manuscripts, including the Alexandrine, Sinaitic, and Codex Ephraemi Rescriptus. It is, therefore, omitted in some modern translations. Scholar Robert Young stated, with regard to "I am the Alpha and the Omega" in 1:11, the "oldest [manuscripts] omit" it. A similar reference is in Isaiah 44, where the Father says to be the first and the one who is after all. Christianity Alpha (Α) and omega (Ω) are the first and last letters, respectively, of the classical (Ionic) Greek alphabet. Thus, the phrase "I am the alpha and the omega" is further clarified with the additional phrase, "the beginning and the end" in Revelation 21:6, 22:13. The first and last letters of the Greek alphabet were used because the book of Revelation is in the New Testament, which was originally written in Greek. This phrase is interpreted by many Christians to mean that Jesus has existed for all eternity or that God is eternal. Many commentators and dictionaries ascribe the title "the alpha and the omega" to both God and to Christ. Barnes' Notes on the New Testament (1974) claims: "It cannot be absolutely certain that the writer meant to refer to the Lord Jesus specifically here ... There is no real incongruity in supposing, also, that the writer here meant to refer to God as such." Most Christian denominations also teach that the title applies to God (Jesus, the Father and
