Alpha & Omega (Gr. "το 'Αλφα και το Ω") is an designation of Jesus and God in the book of Revelation (verses 1:8, 21:16, and 22:13). Its meaning is detected in the fact that Alpha(Α) and Omega(Ω) are respectively the first and last letters of the Greek alphabet. This would become similar to on to individual around English when "the A to Z". So, twice after a title appears these are farther clarified by owning a extra title "the Beginning and the End" (21:16, 22:13).

A attribution of this title to each Jesus & God per creator of Revelation shows he believes there is a unique association between Jesus & God. Such exaltation of Jesus by ascribing to him god occurs as most common theme in the apocalypse.

So a letters Alpha & Omega around juxtaposition come typically utilized as a Christian ocular symbol (watch examples).
