LRMole, if you walk into any Unity Church, (not Unitarian, it is different) you will not see a cross, you will see a set of wings, with an orb in the center, above the altar which are symbolic of the positive outcome of the cruxifiction. Unity is a metaphysical church which focusses on the positive and the metaphysical meanings of the bible. They also use a dove rising up with an olive branc of peace in its mouth as a symbol.

Likewise, while not a religion, but a study of metaphysic, which touches on spirituality, the Rosicrucian Order - AMORC also uses wings as a positive symbol.
