Kingly Office of Christ: One of the three special relations in which Christ stands to his
people. Christ's office as mediator comprehends three different
functions, viz., those of a prophet, priest, and king. These are not
three distinct offices, but three functions of the one office of
mediator. Christ is King and sovereign Head over his Church and over
all things to his Church
(Ephesians 1:22; 4:15; Colossians 1:18; 2:19) He executes
this mediatorial kingship in his Church, and over his Church, and over
all things in behalf of his Church. This royalty differs from that
which essentially belongs to him as God, for it is given to him by the
Father as the reward of his obedience and sufferings
(Philippians 2:6-11)
and has as its especial object the upbuilding and the glory of his
redeemed Church. It attaches, moreover, not to his divine nature as
such, but to his person as God-man. Christ's mediatorial kingdom may
be regarded as comprehending,
1. his kingdom of power, or his providential government of the
universe;
2. his kingdom of grace, which is wholly spiritual in its subjects
and administration; and
3. his kingdom of glory, which is the consummation of all his
providential and gracious administration.
Christ sustained and exercised the function of mediatorial King as well
as of Prophet and Priest, from the time of the fall of man, when he
entered on his mediatorial work; yet it may be said that he was
publicly and formally enthroned when he ascended up on high and sat
down at the Father's right hand
(Psalms 2:6; Jeremiah 23:5; Isaiah 9:6) after his
work of humiliation and suffering on earth was "finished."
