I cannot imagine an affirmation that would meet with more resistance from contemporary Westerners than the one Paul makes in 1 Timothy 2:5: “For there is one God, and there is one mediator between God and men, the man Christ Jesus.” This declaration is narrow and downright un-American. We have been inundated with the viewpoint that there are many roads that lead to heaven, and that God is not so narrow that He requires a strict allegiance to one way of salvation. If anything strikes at the root of the tree of pluralism and relativism, it is a claim of exclusivity to any one religion. A statement such as Paul makes in his first letter to Timothy is seen as bigoted and hateful.
Paul, of course, is not expressing bigotry or hatefulness at all. He is simply expressing the truth of God, the same truth Jesus taught when He said: “I am the way, and the truth, and the life. No one comes to the Father except through me” (John 14:6). Paul is affirming the uniqueness of Christ, specifically in His role as Mediator. A mediator is a go-between, someone who stands between two parties that are estranged or involved in some kind of dispute. Paul declares that Christ is the only Mediator between two parties at odds with one another — God and men.
