📖 Biblical Definition
Christ is the Mediator of the New Covenant — the one Person who stands between God and humanity to reconcile them. "There is one God, and there is one mediator between God and men, the man Christ Jesus" (1 Timothy 2:5). The book of Hebrews develops this theme extensively: Christ is the mediator of a better covenant, enacted on better promises (Hebrews 8:6), sealed not with the blood of animals but with His own blood (Hebrews 9:15). As Mediator, Christ fulfills three offices: Prophet (revealing God's will), Priest (offering Himself as the sacrifice and interceding for His people), and King (ruling over all things). He alone qualifies because He is both fully God and fully man — able to represent both parties.
📜 Webster 1828 Definition
Mediator: one who interposes between parties at variance for the purpose of reconciling them.

MEDIATOR, n. [L.] One that interposes between parties at variance for the purpose of reconciling them. Christ is the mediator, the divine intercessor through whom sinners may be reconciled to an offended God. Note: Webster understood mediation as reconciliation of parties at variance — emphasizing that the relationship between God and man is broken by sin and requires divine intervention.

⚠️ Modern Corruption
Christ's exclusive mediation has been undermined by the multiplication of human mediators and the denial of the need for mediation at all.

Two errors attack Christ's mediation. First, religious systems that insert human mediators — saints, Mary, priests, pastors — between the believer and God. Paul's statement is exclusive: there is ONE mediator. No human being, however holy, can stand between a sinner and God. Second, liberal theology denies the need for mediation altogether, claiming that God accepts all people directly without the cross. But if no mediation were needed, then Christ died for nothing (Galatians 2:21). The need for a mediator underscores the gravity of sin: the gap between holy God and sinful man is so vast that only God-become-man could bridge it.
Usage
• "There is one Mediator between God and men — not Mary, not saints, not priests, but the man Christ Jesus alone."
• "Christ mediates a better covenant because it is sealed with better blood — His own, shed once for all."
