Albert Barnes' Bible Commentary
1 John 2:20
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; compare the notes at Matthew 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,” Revelation 1:6; Revelation 5:10, and as a “royal priesthood” 1 Peter 2:5, 1 Peter 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 John 16:13 note; 1 Corinthians 2:15 note. The meaning cannot be that they knew all things pertaining to history, to science, to literature, and to the arts; but that, under the influences of the Holy Spirit, they had been made so thoroughly acquainted with the truths and duties of the Christian religion, that they might be regarded as safe from the danger or fatal error. The same may be said of all true Christians now, that they are so taught by the Spirit of God, that they have a practical acquaintance with what religion is, and with what it requires, and are secure from falling into fatal error. In regard to the general meaning of this verse, then, it may he observed:
I. That it does not mean any one of the following things:
(1) That Christians are literally instructed by the Holy Spirit in all things, or that they literally understand all subjects. The teaching, whatever it may be, refers only to religion.
(2) It is not meant that any new faculties of mind are conferred on them, or any increased intellectual endowments, by their religion. It is not a fact that Christians, as such, are superior in mental endowments to others; nor that by their religion they have any mental traits which they had not before their conversion. Paul, Peter, and John had essentially the same mental characteristics after their conversion which they had before; and the same is true of all Christians.
(3) It is not meant that any new truth is revealed to the mind by the Holy Spirit. All the truth that is brought before the mind of the Christian is to be found in the Word of God, and “revelation,” as such, was completed when the Bible was finished.
(4) It is not meant that anything is perceived by Christians which they had not the natural faculty for perceiving before their conversion, or which other people have not also the natural faculty for perceiving. The difficulty with people is not a defect of natural faculties, it is in the blindness of the heart.
II. The statement here made by John “does” imply, it is supposed, the following things:
(1) That the minds of Christians are so enlightened that they have a new perception of the truth. They see it in a light in which they did not before. They see it as truth. They see its beauty, its force, its adapted less to their condition and wants. They understand the subject of religion better than they once did, and better than others do. What was once dark appears now plain; what once had no beauty to their minds now appears beautiful; what was once repellant is now attractive.
(2) They see this to be true; that is, they see it in such a light that they cannot doubt that it is true. They have such views of the doctrines of religion, that they have no doubt that they are true, and are willing on the belief of their truth to lay down their lives, and stake their eternal interests.
(3) Their knowledge of truth is enlarged. They become acquainted with more truths than they would have known if they had not been under the teaching of the Holy Spirit. Their range of thought is greater; their vision more extended, as well as more clear.
III. The evidence that this is so is found in the following things:
(1) The express statements of Scripture. See 1 Corinthians 2:14, and the notes at that passage. Compare John 16:13.
(2) It is a matter of fact that it is so.
(a) People by nature do not perceive any beauty in the truths of religion. They are distasteful to them, or they are repulsive and offensive. “The doctrine of the cross is to the Jew a stumbling-block, and to the Greek foolishness.” They may see indeed the force of an argument, but they do not see the beauty of the way of salvation.
(b) When they are converted they do. These things appear to them to be changed, and they see them in a new light, and perceive a beauty in them which they never did before.
(c) There is often a surprising development of religious knowledge when persons are converted. They seem to understand the way of salvation, and the whole subject of religion, in a manner and to an extent which cannot be accounted for, except on the supposition of a teaching from above.
(d) This is manifest also in the knowledge which persons otherwise ignorant exhibit on the subject of religion. With few advantages for education, and with no remarkable talents, they show an acquaintance with the truth, a knowledge of religion, an ability to defend the doctrines of Christianity, and to instruct others in the way of salvation, which could have been derived only from some source superior to themselves. Compare John 7:15; Acts 4:13.
(e) The same thing is shown by their “adherence to truth” in the midst of persecution, and simply because they perceive that for which they die to be the truth. And is there anything incredible in this? May not the mind see what truth is? How do we judge of an axiom in mathematics, or of a proposition that is demonstrated, but by the fact that the mind “perceives” it to be true, and cannot doubt it? And may it not be so in regard to religious truth - especially when that truth is seen to accord with what we know of ourselves, our lost condition as sinners, and our need of a Saviour, and when we see that the truths revealed in the Scriptures are exactly adapted to our wants?
