Biblical Word Etymology
The Etymology of “Mediator”
The biblical word “Mediator” traces back to Hebrew / Greek (mesit (Hebrew), mesites (Greek)), where it meant “One who stands in the middle, intercedes between parties”. Across 3eras it evolved into the modern sense: “One who intervenes to settle disputes; in theology, Christ's intercession”.
