I think you may be confusing Atheism and Alchemy. Flamel's Cross is a symbol used alchemy and, as far as I can tell, has nothing whatsoever to do with theism or atheism.
EDIT: I will not debate aethism and religion here, however, Flamel's Cross is named after Nicholas Flamel who was said to have created a Philosopher's Stone and was a practitioner of Alchemy. Flamel was an ardent and dedicated Catholic and was very interested in Hermetic as well as Kabbalist (Christian and Judaic) Mysticism. Much of Hermetic alchemy is rooted in Christian and Judaic mysticism, so to ask if Flamel's Cross is a symbol of atheism is like asking if water is dry. Basically, the answer is no.
