1 John 2:20

“But ye have an unction from the Holy One, &c.] Meaning the Spirit, and his graces, with which Christ, the head, is anointed without measure, and his members in measure; from whence he is called Christ, and they Christians. These were really the Lord's anointed ones; they were true believers; were the wise virgins who had oil in their vessels with their lamps, which would never go out. The grace of the Spirit is called a chrism, or an ointment, or an anointing, in allusion to the anointing oil under the law; (see Gill on “<402503>Matthew 25:3”); of which anointing oil the Jews say f32, that it continues all of it, awbl dyt[l, “to time to come”, (i.e. to the times of the Messiah,) as it is…”

“But--Greek, "And." He here states the means which they as believers have wherewith to withstand. Antichrists (Jo1 2:18), namely, the chrism (so the Greek: a play upon similar sounds), or "anointing unguent," namely, the Holy Spirit (more plainly mentioned further on, as in John's style, Jo1 3:24; Jo1 4:13; Jo1 5:6), which they ("ye" is emphatical in contrast to those apostates, Jo1 2:19) have "from the Holy One, Christ" (Joh 1:33; Joh 3:34; Joh 15:26; Joh 16:14): "the righteous" (Jo1 2:1), "pure" (Jo1 3:3), "the Holy One" (Act 3:14) "of God"; Mar 1:24. Those anointed of God in Christ alone can resist those anointed with the spirit of Satan, Antichrists, who would sever them from the Father…”

“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, (1 Samuel 10:1; 1 Samuel 16:13; Exodus 28:41; Exodus 40:15;…”

“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. St. John here but just touches upon the Holy Ghost, of whom he speaks more largely, Jo1 3:24; Jo1 4:13; Jo1 5:6. 1 John 2:21”

“2:20-23 for the Holy One has given you his Spirit: The Holy Spirit gives believers the ability to understand and recognize spiritual truth (see Isa 61:1; Acts 10:38; 2 Cor 1:21-22). Those who have the Spirit know the truth about the Father and the Son and can detect what does not accord with the truth of the apostles’ teaching.”
