Saturday Symbol: Alpha & Omega

The term Alpha and Omega comes from the phrase "I am the alpha and the omega" an appellation of Jesus in the Book of Revelation (verses 1:8, 21:6, and 22:13).

Its meaning is taken from the fact that alpha (Α) and omega (Ω) are the first and last letters of the Classical (Ionic) Greek alphabet.  This symbol comes from the belief, by many christians, that Christ, as well as the Father, is "the First and the Last" therefore Alpha and Omega in juxtaposition are often used as a Christian visual symbol.

This symbol was accompanied by the group name.

The symbol itself is actually a Jerusalem Cross also called the Crusaders' Cross. It is made up of 5 Greek Crosses which are said to symbolize the 5 Wounds of Christ or the 4 Gospels and the 4 corners of the earth (the 4 smaller crosses) and Christ Himself (the large Cross). The Knights of the Holy Sepulchre adopted it as their symbol.
