||Christianity as dualistic was my stance since he mentioned it being monistic. Your attempt to argue my choice of examples does not signify any failure to understand the concept on my part. I chose those as my examples, because they are the easiest to recognize and relate to. NOT because I had nothing else to go on.
Oh and by the way, given my examples of Heaven and Hell, flesh and spirit, Salvation and Damnation (sin), it would be easy to say that I have given enough support for my argument in a significant variation -- as opposed to relying on one source that does not support my claim.
Oh, and to clarify what you failed to grasp. Because the Devil and God are in opposition, there must be, by deduction, two forces. In other words dualism. Monism states that there is only one force and that all things can be reduced to this force (principle, concept, whatever). So, if we were to go with Monism then the Devil is in fact NOT in opposition with the Lord, but is in fact the Lord acting upon His own Will. Also, there would be no difference between Sin and Salvation, Heaven and Hell, flesh and spirit, and so on. Because, according to Monism, they are all reduced to the same principle (ie Sin is Salvation, Spirit is Flesh, and vice versa and so on). Now, I doubt very seriously that most Christians would agree with these statements. Although, if you want to get down to the nuts and bolts they can be justified. It might be noted that humans were given Free Will by the Lord, and as such are given the chance to make choices (whether correct or incorrect). This also denotes the neccessity of two things. You cannot make a choice if there is but one, you can only accept what already is.
They are not irrelevant, because they all serve to illustrate the concepts that drive Christianity. Christianity is a religion based upon the whole of its ideology, dogma, and philosophy. It is not a religion capable of being defined by being broken down into simplistic models. This is an error Pagans and Wiccans make when discussing Christianity. It is also an error Christians make when discussing Pagans and Wiccans. These religions are living traditions and the removal of any aspect of the tradition serves only to defeat the tradition and, in my opinion, somehow lessen it.
