Atheists are not really A-theist. They do worship a god, it's just not the One True God; the God of Abraham, Isaac, Jacob, and Pope Benedict. A recent article covers how a group of Connecticut atheists have taken "advantage of a town's policy of allowing holiday-season displays in its public park" by putting up a 10-foot tall sign celebrating the winter solstice. An idea in modern society, that is, celebrating a Christless Christmas, that Pope Benedict calls 'senseless'. The sign reveals what god they really do worship.
Part of the sign reads: ". . . Today we know that there are no gods, and that the sun moves by natural causes, and we celebrate not only the movement of the sun but our ability to understand that movement." Their fancy wordplay only reveals their true colors. They have placed not only themselves as gods with humanistic-self-grandisement, but have chosen the sun as their modern 'golden calf' to worship, bypassing the Creator for the creation. What is trumpeted as atheism today, was for past centuries more accurately referred to as idolatry.
