"For there is one God, and there is one mediator between God and men, the man Christ Jesus" (1 Timothy 2:5 RSV).
Bible scholars find it difficult to ascribe the two Timothy letters to the apostle Paul, and this statement is an illustration of why. The emphasis in this letter is on the structure of the new religion—forms of worship, qualifications for bishops and deacons, and so on. Paul's vision, particularly his understanding of "the Christ," was much more universal. Paul is less concerned with "the man, Christ Jesus," whom he regards as a divine expression of our own spiritual Truth. His emphasis is on opening to the truth of our own Christ nature, of which Jesus is a perfect example.
Both Paul and the author of this letter would, of course, agree that spiritual Truth begins with the realization of "one God." If the Power we call God is truly omnipotent, omniscient, and omnipresent, that would mean that everything—including every religion—is contained within that Allness. So those religions don't "lead to God"—they are already contained within God. Similarly, there is no "path to eternal life." We are expressions of eternal life. Our spiritual work, therefore, is to find a path—perhaps a religion, perhaps not—that guides us to explore and express the Truth of who we are—creative expressions of the infinite, eternal energy that is God.
