As much as I would love to get into a philosophical and religious debate, I'm going to avoid those subjects. Simply, I voted yes, because I believe that was Tolkien's intention. Whether or not Eru matches with our idea of God, Christian or otherwise, Eru is most likely how Tolkien veiwed the Christian God. No one ever said he was right or wrong, or what it meant for the people of ME. Tolkien followed the Christian God, so it stands to reason that he formed Eru after his God.
Good arguments to everyone though.
And where's your vote, Fordim?
