G7
What does "G" really stand for?
Maybe this:
The letter "G" figures prominently in Freemasonry. In the lower degrees, the initiate is told that this letter stands for "God" and for "Geometry", which the Supreme Architect of the Universe used to design this wonderful Cosmos. However, occultist, and 33rd Degree Mason, Arthur Waite, quotes Eliphas Levi [also 33rd Degree], telling us that the letter "G" stands for Venus, and that Venus' symbol is a lingam, a stylized phallis. [Masonic author, Arthur Edward Waite, The Mysteries of Magic: A Digest of the Writings of Eliphas Levi , Chicago, , DeLaurence, Scott, and Company, 1909, p. 217]
The greatest Masonic author of all time, Albert Pike, agrees. He states [page 631-32 in Morals and Dogma ] that the Monad [#1] is male, and the Duad [#2] is female. Their sexual union produces the Triad [#3], which is "represented by the letter 'G', the generative principle". This term, "generative principle", is code for the sex act.
