The context here is the New Covenant that bridges the massive gap between God and man. To reconcile two estranged parties, a mediator must equally represent both parties. No angel, prophet, or mere man could fill this role.
A sinful man could not stand before God on behalf of others (cf. Job 9:33). Only one who shares in our humanity yet is also equal with God can bring the two together. That's why there is only one Mediator between man and God.
Christ alone is qualified. Only because Jesus is both God and man can He be the Mediator who brings salvation.
Furthermore, 1Tim 2:15 is Monotheistic, Not Arian. When Paul says, “there is one God,” he is affirming biblical monotheism. He is not excluding Christ from that oneness but situating Him within it. In fact within 1Cor 8:6, Paul redefines Israel’s Shema (“Hear O Israel, the LORD is one”) to include both the Father and the Son within the one God. Thus, “the man Christ Jesus” in 1 Timothy 2:5 is not a denial of His divinity but an emphasis on His humanity in the mediatorial role.
Conclusion:
1 Timothy 2:5 does not support Arianism. Instead, it teaches the very opposite:
- The New Covenant offers salvation through a Mediator.
- That Mediator must be both God and man.
- Jesus uniquely fulfills this role.
- Scripture elsewhere affirms Jesus as fully God.
- The verse itself affirms monotheism without excluding Christ from deity.
Therefore, this verse actually confirms the deity of Christ and His unique role as Savior.
