The act of a go-between — one who stands between two estranged parties to reconcile them. In the supreme biblical sense, mediation refers to the unique office and work of Jesus Christ, the one and only Mediator between God and man (1 Tim 2:5). Christ's mediation is not merely diplomacy but substitutionary: He does not simply carry messages between parties — He bears the penalty of the estranged party (mankind) and satisfies the just demands of the offended party (God), thereby achieving actual reconciliation. His mediation encompasses His prophetic office (revealing God to man), His priestly office (interceding on our behalf and offering Himself as sacrifice), and His kingly office (ruling all things for the good of His people). No prayer reaches the Father except through the mediation of the Son (John 14:6).
MEDIA'TION, n. 1. Interposition between parties at variance, with a view to reconcile them; agency between persons. 2. In theology, the act of Christ in interposing between God and man, to reconcile them; the atonement. The mediation of Christ secures the pardon of sinners, and their reconciliation to God; it is the foundation of the covenant of grace, and of all the blessings of the gospel.
Rome corrupted mediation by inserting a hierarchy of secondary mediators — Mary, saints, and priests — between the believer and God, obscuring the sufficiency of Christ's unique mediatorial work. Progressive Christianity erases the need for mediation altogether by denying that God is truly offended by sin or that estrangement between God and man is real. Both errors make Christ's mediation unnecessary — one by adding to it, the other by denying the problem it solves. Secularism reduces "mediation" to mere conflict-resolution, evacuating any cosmic dimension. The biblical view insists: the estrangement between holy God and sinful man is absolute, real, and lethal — and only one Mediator can bridge it.

Hebrews 9:15 — "For this reason He is the mediator of a new covenant, so that, since a death has taken place for the redemption of the transgressions..."
John 14:6 — "I am the way, and the truth, and the life; no one comes to the Father but through Me."
Hebrews 7:25 — "He is able also to save forever those who draw near to God through Him, since He always lives to make intercession for them."
Romans 8:34 — "Christ Jesus is He who died, yes, rather who was raised, who is at the right hand of God, who also intercedes for us."

• "Christ's mediation is not passive diplomacy — He is the bridge, the payment, and the peace. His body is the treaty between God and man."
• "When we pray 'in Jesus' name,' we are invoking the one Mediator — acknowledging that our access to the Father is entirely derivative of His completed work."
• "No saint, no priest, no institution can add to or replace the singular mediation of Christ. He alone is both fully God and fully man — the only one qualified to stand in the middle."
