The term Alpha and Omega comes from the phrase "I am the alpha and the omega" (Koiné Greek: τὸ Α καὶ τὸ Ω), an appellation of God in the Book of Revelation (verses 1:8, 21:6, and 22:13). Its meaning is found in the fact that Alpha (Α) and Omega (Ω) are respectively the first and last letters of the Classical (Ionic) Greek alphabet. This would be similar to referring to someone in English as "the A to Z". Thus, twice when the title appears it is further clarified with the additional title "the Beginning and the End" (21:6, 22:13).
      Therefore the letters Alpha and Omega in juxtaposition are often used as a Christian visual symbol. We have included four clip art versions of this symbol for white web pages here. For versions of the Labarum designed for black web pages go here.
