Our deeds, our actions and our words will save us on their own. Therefore, if one feels the need to accept Jesus as his Lord and personal savior, then he obviously does not believe that we are capable of self salvation, in which case, he simply is not Wiccan. Wicca is a polytheistic religion, which means that we see the forms of god in many shapes, with many faces and many names. While not all Wiccans are polytheist, but rather see all these gods as nothing more than facets of One God, Wiccan monotheists accept polytheism as a valid way to see the divine. The religion of Wicca itself of polytheistic, meaning that is allows for our vision of God to include more than one deity, but it does not require it.
Monotheism is a personal choice made by individual practitioners.
Polytheism, however, is absolutely rebuked by Christianity, Judaism, and Islam. As the society became increasingly more patrifocal and steadfast in their attempts to break away from all pagan influences upon their religion, the Shekinah was abolished. Many modern Jewish traditions, however, are starting to bring the Shekinah back into their worship. Monotheistic religions are prohibitive of the worship of other deities, and even of the idea of worshipping a single Deity by many names or faces. In yet another respect, Wicca and these religions are incompatible.
