Eru Ilúvatar
The influence of the Bible is seen in the conflict between Melkor and Eru Ilúvatar, a parallel of the polarity of Lucifer and God. Further, the creation and fall of the Elves parallels the "Genesis" account of the creation and fall of Man. As with all of Tolkien's works, "The Silmarillion" allows room for later Christian history, and one draft even has Finrod speculating on the necessity of Eru's (God's) eventual Incarnation to save mankind.
