I agree. Deity is so much more that we can define.
Freebubbles- When someone works with specific "named" deities - like the different gods and goddesses of the Greek or Egyptian pantheon, they are working with specific "faces" or aspects of the god and goddess... for example if they work with Aphrodite (Greek) they are working with the Goddess in her love aspect, if it is Sekmhet (Egyptian) that is a warrior/defender/destroyer aspect so the two energies may not be compatable to work with at the same time.
