It is not to be wondered at that the Israelites had such frequent use of anointings, when we consider that the very order of their institution as a church and people, was to be looking for the coming of the Messiah, that is, the anointed One. Hence their kings, priests, vessels, and all things consecrated, had the unction. (See Exodus 30:23)
How holy and blessed is it to the church of Jesus now, to discover that in this unction, thus figuratively set forth in the old church, all the outlines of the Lord Jesus anointing by the Holy Ghost, and the church also in him were displayed. Now, as Christ the Messiah could not have been Christ, that is, anointed, but by the Holy Ghost's anointing, so neither could the church have been his church, his spouse, his beloved, and the only one, of her mother, (Song of Solomon 6:9) but by the anointing also of God the Holy Ghost. Hence then it should be considered, (and I beg the pious reader to consider it, and keep it in remembrance proportioned to its infinite importance) as Christ is called Messiah, that is Christ, as the anointed of God, before he openly appeared at his incarnation, so the church of Christ is called his church; and for which, in salvation-work, Christ was made Christ, before he was made flesh, and dwelt among us; nor, as the Son of God, had it not been for his church's sake, ever would have been sent by the Father, neither would have taken our nature into the GODHEAD, neither have been anointed by the Holy Ghost. So by his becoming the anointed for this express purpose, proves the original anointing of the church in him, and for him; and sets forth the everlasting love of all the persons of the GODHEAD to the church of Christ in all ages.
