God (I think, or Jesus) from the bible (Revelations?)

Omega is the last letter of the greek alphabet and just sounds cool. Thus, Omega Weapon is the Ultimate weapon (unlike ultima, which I believe is the previous month).
Revelation 22:12 "And behold, I am coming quickly, and My reward is with Me, to give to every one according to his work. I am the Alpha and the Omega, the Beginning and the End, the First and the Last." -this is Jesus speaking in trinitarian versions of the bible.
Though there are a lot of religious undertones to several Final Fanatisies, I don't think that the alpha and omega weapon are correlated with the Christianity thought, as much as the greko-roman thoughts of creation vs extinction. I for one, think Omega weapon in VIII was quite awsome ~ and the traditional staple enemy fight is very cool.
