Christ, the Mediator (Stephen Charnock)

1 Timothy 2:5

“For there is one God, and one mediator between God and men, the man Christ Jesus;” 

Christ is said to be the one Mediator in the same sense that God is said to be the one God. As there is but one Creator of man, so there is but one Mediator for men. As God is the God of all that died before Christ came, as well as of those that died after; so Christ is the Mediator of all that died before his coming, as well as of those that saw his day. They had Christ for their Mediator, or some other; some other they could not have had, because there is but one. They might as well have had another Creator besides God, as another Mediator besides the man Christ Jesus. In regard of the antiquity of his mediation, from the foundation of the world, he is represented, when he walks as Mediator 'in the midst of the seven golden candlesticks,' with 'hair as white as wool,' a character of age (Rev. i. 14); as God is described so in regard of his eternity, (Dan. vii. 9.) There is but one God from eternity; but one Mediator, whose mediation hath the same date as the foundation of the world, and runs parallel with it.
