2:11 {12} For both he that {r} sanctifieth and they who are sanctified [are] all of {s} one: for which cause he is not ashamed to call them brethren,
(12) The basis for both of the former arguments, for we could not be sons through him, neither could he be consecrated through afflictions, unless he had been made man like us. But because this sonship depends not only on nature, for no man is accounted the son of God, unless he is also a son of a man, he is also Christ's brother, (which is by sanctification, that is, by becoming one with Christ, who sanctifies us through faith) therefore the apostle makes mention of the sanctifier, that is, of Christ, and of them that are sanctified, that is, of all the elect, who Christ condescends to call brethren.
(r) He uses the time to show us that we are still going on, and increasing in this sanctification: and by sanctification he means our separation from the rest of the world, our cleansing from sin, and our dedication wholly to God, all which Christ alone works in us.
(s) One, of the same nature of man.
2:11 Both he that sanctifieth and they who are sanctified. He who makes men holy by purging them of their sins, and those who are made holy are
all of one. Are made of one nature because he took our nature and suffered. Hence
he is not ashamed to call them, all the saved, though they are mortals, by the name of
brethren. This is done in the Hebrew Scriptures (Ps 22:22). The language quoted from the Psalm is ascribed to Christ, but is addressed to God. The point is that the speaker calls the worshipers brethren.
2:11 For - They are nearly related to each other. He that sanctifieth - Christ, Heb 13:12. And all they that are sanctified - That are brought to God; that draw near or come to him, which are synonymous terms. Are all of one - Partakers of one nature, from one parent, Adam.
2:10-13 Whatever the proud, carnal, and unbelieving may imagine or object, the spiritual mind will see peculiar glory in the cross of Christ, and be satisfied that it became Him, who in all things displays his own perfections in bringing many sons to glory, to make the Author of their salvation perfect through sufferings. His way to the crown was by the cross, and so must that of his people be. Christ sanctifies; he has purchased and sent the sanctifying Spirit: the Spirit sanctifies as the Spirit of Christ. True believers are sanctified, endowed with holy principles and powers, set apart to high and holy uses and purposes. Christ and believers are all of one heavenly Father, who is God. They are brought into relation with Christ. But the words, his not being ashamed to call them brethren, express the high superiority of Christ to the human nature. This is shown from three texts of Scripture. See Ps 22:22; 18:2; Isa 8:18.
