The oldest argument, not only in Christianity, but in all religions, is how and/or whether the individual can experience Oneness with the Universal Spirit, sometimes called God, or the Creator. Is it through enlightenment, spiritual awakening, or self-realization? Or is it through the intervention of some orthodox religion, salvation through the doctrines and dogmas of the Church? Can the truth – the Way, the Path, whatever you want to call it – only be handed to you from without by some authorized representative of orthodox religion, or can you find it within by using your wits and trusting your eternal nature?
