“I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty”.
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 couple of letters are used as Christian symbols, and are often combined with the Cross, Chi-rho, or other Christian symbols.
The term Alpha and Omega comes from the phrase “I am the alpha and the omega” (Koiné Greek: “ἐγὼ τὸ Α καὶ τὸ Ω”), an appellation of Jesus.
God the Father and Jesus share many of the same designations, mostly because of the limits of language. Lord, King, Master, Savior and Alpha and Omega. The context where these attributions are used is necessary to determine their application.
You can be the Master or Lord of your house, God is the one who instituted salvation, it belongs to God and is run through Jesus (Col. 1:19). The Alpha and Omega distinction means wth respect to God, He is the First and Last God, whereas with Jesus, the designation means He is the first and last Savior for men. Salvation is Gods creation administered through Jesus.
“ I, even I, am the Lord; and beside me there is no saviour”.
21 “Tell ye, and bring them near; yea, let them take counsel together: who hath declared this from ancient time? who hath told it from that time? have not I the Lord? and there is no God else beside me; a just God and a Saviour; there is none beside me.
22 Look unto me, and be ye saved, all the ends of the earth: for I am God, and there is none else”.
18 And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence.
19 For it pleased the Father that in him should all fulness dwell;
“Thus saith the Lord the King of Israel, and his redeemer the Lord of hosts; I am the first, and I am the last; and beside me there is no God”.
In the Book of Revelation (verses 1:8, 21:6, and 22:13). The first part of this phrase (“I am the Alpha and Omega”) is first found in Chapter 1 verse 8, and is found in every manuscript of Revelation that has chapter 1 verse 8. Several later manuscripts repeat “I am the Alpha and Omega” in chapter 1 verse 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.
Alpha (Α) and Omega (Ω) are the first and last letters, respectively, of the classical (Ionic) Greek alphabet. Twice when the phrase “I am the alpha and the omega” appears, it is further clarified with the additional phrase, “the beginning and the end” (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 Koine Greek.
The letters Alpha and Omega in juxtaposition are often used as a Christian visual symbol. The symbols were used in early Christianity and appear in the Roman catacombs. The letters were shown hanging from the arms of the cross in Early Christian art, and some crux gemmata, some jeweled crosses in precious metal, have formed letters hanging in this way, called pendilia; for example, in the Asturian coat of arms, which is based upon the Asturian Victory Cross. They are often shown to the left and right of Christ’s head, sometimes within his halo, where they take the place of the Christogram used in Orthodox art. I hope this helps…..
