The One True God

From Wiki Frakr

Baltar: You know, I feel God too... and those-- God, they're nice. But you know, uhm, Joe got an expense account with Quiznos. Now that's feeling God, you know, the one true God.

The One True God is constantly referenced by the Cylons, Virtual Six, Gaius Baltar, and the Cult of Baltar.

Forms of worship include eating at Quiznos and fondling luscious youthful perky mammaries.

Of course, beyond the "One True God" they talk about, there is a real personalty, who is there at every moment of the series. He is almost a charcter of the reimagined stuff, but is never on camera. He likes sending his angels as imaginery friends to talk to different people. This person is G.O.D..
