1 John 2:20

But you have an anointing from the Holy One, and you know all things. The spiritual anointing is the Holy Spirit, whose sacrament is in the visible anointing. He says that all who have this anointing of Christ have the ability to discern the good …

This is what each of us has received at baptism.

So that after the apostle had said the foregoing, no one would think that he ascribes the knowledge of this to himself alone and therefore boasts of it before the other believers, he fittingly adds: "and you have an anointing." He speaks as if to …

But ye have an anointing - A chrism; perhaps so termed in opposition to the name of antichrist; an inward teaching from the Holy Ghost, whereby ye know all things - Necessary for your preservation from these seducers, and for your eternal salvation.

The Lord Christ does not deal alike by all his professed disciples; some are more anointed than others. There is great danger lest those that are not thus anointed should be so far from being true to Christ that they should, on the contrary, turn antichrists, and prove adversaries to Christ's person, and kingdom, and glory.

But ye have an unction - The word χρισμα signifies not an unction, but an ointment, the very thing itself by which anointing is effected; and so it was properly rendered in our former translations. Probably this is an allusion to the holy anointing oil of the law, and to Psa 14:7: God hath anointed thee with the oil of gladness - he hath given thee the plenitude of the Spirit, which none of thy fellows - none of the prophets, ever received in such abundance.

"It appears that we all are the body of Christ, because we all are anointed: and we all in Him are both Christ's and Christ, because in some measure the whole Christ is Head and body." and--therefore. ye know all things--needful for acting aright against Antichrist's seductions, and for Christian life and godliness.

But ye have an unction from the Holy One - The apostle in this verse evidently intends to say that he had no apprehension in regard to those to whom he wrote that they would thus apostatize, and bring dishonor on their religion. They had been so anointed by the Holy Spirit that they understood the true nature of religion, and it might be confidently expected that they would persevere. The word “unction” or “anointing” (χρίσμα chrisma) means, properly, “something rubbed in or ointed;” oil for anointing, “ointment;” then it means an anointing. The allusion is to the anointing of kings and priests, or their inauguration or coronation, (1Sa 10:1; 1Sa 16:13; Exo 28:41; Exo 40:15; compare the notes at Mat 1:1); and the idea seems to have been that the oil thus used was emblematic of the gifts and graces of the Holy Spirit as qualifying them for the discharge of the duties of their office. Christians, in the New Testament, are described as “kings and priests,” Rev 1:6; Rev 5:10, and as a “royal priesthood” 1Pe 2:5, 1Pe 2:9; and hence they are represented as “anointed,” or as endowed with those graces of the Spirit, of which anointing was the emblem. The phrase “the Holy One” refers here, doubtless, to the Holy Spirit, that Spirit whose influences are imparted to the people of God, to enlighten, to sanctify, and to comfort them in their trials. The particular reference here is to the influences of that Spirit as giving them clear and just views of the nature of religion, and thus securing them from error and apostasy. And ye know all things - That is, all things which it is essential that you should know on the subject of religion. See the Joh 16:13 note; 1Co 2:15 note. […]
