Well, in the myth of the Egyptian god Osiris, which derived out of the legends of Nimrod, Osiris was said to have been killed by a rival god and cut into 14 different pieces. After cutting the body of Osiris into 14 pieces, this rival god threw all of the parts of Osiris along the Nile. Isis, his wife, found all the pieces but one, his genital member. Now remember, Osiris was worshipped as the Creator, the Impregnating Force of the Universe, so the mother goddess Isis moulded with her hands an image of the dead god’s phallus, and set up one to be venerated as a monument to Osiris [48]. Hence, the origin of Phallicism. So in the Temple services of the pagans, a coffin with an image of Osiris’ phallus in it became part of the worship of the Sun-god. This same phallic image has been passed down through history to us today. Its name is the obelisk, which even a small child should have seen many times. Gross darkness are the deceptions of Satan! The obelisk, the sacred phallic symbol of Osiris (Nimrod), is now standing in St. Peter’s Square at the Vatican, with a cross erected on top of its pyramid. And it’s also standing 555 feet high in Washington, DC. And this is the origin of the church steeple!
The question is does it have any connection with Hindus worshiping the Phallus of Lord Shiva. It is a matter of fact that cross border trade and sciences were shared amongst the then prevalent cultures and civilizations.
