“This question is still more difficult to decide than the preceding. In the Latin version it was formerly called The Epistle of St. John to the Parthians; and this title was adopted by some of the ancient fathers, and in modern times has been defended by Grotius. But if St. John had intended this epistle for the use of the Parthians, he would hardly have written it in Greek, but would have used either the language of the country, or, if he was unacquainted with it, would have written at least in Syriac, which was the language of the learned in the Parthian empire, and especially of the Christians. We know, from the history of Manes, that even the learned in that country were for the most part unacquainted with the Greek language; for to Manes, though he united literature with genius, his adversaries objected that he understood only the barbarous Syriac. That a Grecian book would not have been understood in the Parthian empire, appears from what Josephus says in the preface to his History of the Jewish War, where he declares that a work intended for Parthian Jews must be written, not in Greek, but Hebrew. However, it is worth while to examine whence the superscription ‘ad Parthos’ took its rise. Whiston conjectures that an ancient Greek superscription of this epistle was προς παρθενους, (to virgins), because this epistle is chiefly addressed to uncorrupted Christians, and that this title was falsely copied προς Παρθαυς, whence was derived the Latin superscription, ‘ad Parthos.’ But this conjecture is without foundation; for since the faithful are not called in a single instance throughout the whole epistle by the name of παρθενους, it is very improbable that the title προς παρθενους was ever affixed to it. I would rather suppose, therefore, that the frequent use in this epistle of the words ‘light’ and ‘darkness,’ which occur in the Persian philosophy, and on the same occasions as those on which St. John has used them, gave rise to the opinion that St. John wrote it with a view of correcting the abuses of the Persian philosophy; whence it was inferred that he designed it for the use of the Christians in the Parthian empire. That St. John really designed his epistle as a warning to those Christians who were in danger of being infected with Zoroastrian principles, is very probable, though the language of the epistle will not permit us to place St. John’s readers in a country to the east of the Euphrates.

“That the design of this epistle was to combat the doctrine delivered by certain false teachers, appears from 1Jo 2:18-26; 1Jo 3:7; 1Jo 4:1-3 : and what this false doctrine was may be inferred from the counter doctrine delivered by St. John, 1Jo 5:1-6. The apostle here asserts that Jesus is the Christ,’ and that he was the Christ, ‘not by water only, but by water and blood.’ Now these words, which are not in themselves very intelligible, become perfectly clear if we consider them as opposed to the doctrine of Cerinthus, who asserted that Jesus was by birth a mere man; but that the Aeon, Christ, descended on him at his baptism, and left him before his death. But if what St. John says, 1Jo 5:1-6, was opposed to Cerinthus, the Antichrists of whom he speaks, 1Jo 2:18, 1Jo 2:19, and who, according to 1Jo 2:22, denied that Jesus was the Christ, as also the false prophets, mentioned 1Jo 4:1, 1Jo 4:3, must be Cerinthians, or at least Gnostics. That they were neither Jews nor heathens may be inferred from 1Jo 2:19, where St. John says, ‘They went out from us.’ Farther, he describes them, 1Jo 2:18, as persons who had lately appeared in the world. But this description suits neither Jews nor heathens, who, when this epistle was written, had not lately begun to deny that Jesus was the Christ. Lastly, in the same verse, he describes them as tokens of the last time, saying, ‘As ye have heard that Antichrist shall come, even now there are many Antichrists, whereby we know that it is the last time.’ But this inference could not be drawn from the refusal of the Jews to acknowledge that Jesus was the Messiah. Now, as soon as we perceive that the position, ‘Jesus is the Christ,’ is a counter position against Cerinthus, we may infer, as I have already observed, that the Antichrists who denied that Jesus was the Christ, or who denied that Christ had appeared in the flesh, were Cerinthians; or perhaps the latter were Docetes. It is, therefore, highly probable that the whole epistle, which in various places discovers an opposition to false teachers, was written against Cerinthians, or at least against Gnostics and Magi. A proposition can never be completely understood, unless we know the author’s design in delivering it. For instance, ‘God is light, and in him is no darkness,’ appears to contain a tautology, if we consider it as a detached dogma; and if it be considered as an admonitory proposition, it may be thought to contain a severe reproof; but if we regard it in a polemical view, it will present itself under a very different form. This epistle abounds with exhortations; but no man who wishes to understand it will be satisfied without asking the following questions: Why did St. John give these admonitions? Why has he so frequently repeated them? Why has he admonished, if he thought admonition necessary, merely in general terms, to holiness and brotherly love? And why has he not sometimes descended to particulars, as other apostles have done? An answer to these questions will throw great light on the epistle; and this light I will endeavor to procure for the reader, by pointing out the several propositions which, in my opinion, are laid down in opposition to Gnostic errors.

“1. In the first chapter the four first verses are opposed to the following assertion of the Gnostics: ‘That the apostles did not deliver the doctrine of Jesus as they had received it, but made additions to it, especially in the commandments which were termed legal; whereof they themselves (the Gnostics) retained the genuine and uncorrupted mystery.’ St. John therefore says: ‘That he declared that which was from the beginning, which he himself had seen and heard;’ that is, that he taught the doctrine of Christ as it was originally delivered, as he had heard it from Christ’s own mouth, whose person he had seen and felt; and that he made no additions of his own, but only reported as a faithful witness. In like manner he appeals, 1Jo 2:13, 1Jo 2:14, to the elder Christians, whom he calls fathers, ‘because they knew him who was from the beginning;’ that is, because they knew how Christ had taught from the beginning; and 1Jo 2:24, he says: ‘Let that abide in you which ye have heard from the beginning.’ Farther he says, 1Jo 2:7 : ‘Brethren, I write no new commandment unto you, but an old commandment, which ye had from the beginning.’ In the next verse he adds: ‘Again a new commandment I write unto you, which thing is true in him and in you, because the darkness is past, and the light now shineth.’ Now Christ himself had given his disciples a commandment which he called a new commandment, and this was, ‘that they should love one another.’ The term ‘new commandment,’ therefore, St. John borrowed from Christ; but in the present instance he appears to have applied it to a different subject, because the special command which Christ gave to his disciples, that they should love one another, and which he called a new commandment, could not well be called an old commandment, being very different from the general commandment, that we should love our neighbor. St. John, therefore, very probably meant that the commandment of love and sanctification was no new commandment, as the Gnostics contended, but the old commandment which the Christians had heard from the beginning. It was, indeed, become a new commandment, in consequence of the false doctrines which then prevailed; or rather, it appeared to be so, because the Gnostics had endeavored to banish it from their system of theology. But whether a new or an old commandment, St. John thought proper to enforce it.

“2. The Gnostics, who contended that those commandments which were legal were not given by Christ, but were added by the apostles without his authority, counteracted, by so doing, the whole doctrine of sanctification. St. John, therefore, devotes the greatest part of his epistle to the confirmation and enforcement of this doctrine. In 1Jo 1:5, 1Jo 1:7, he asserts, as a principal part of the message which he had heard from Christ, that no one who does not walk in the light has fellowship with God. In the three following verses he limits this proposition in such a manner as was necessary in arguing with an adversary; and 1Jo 2:1, 1Jo 2:2, he removes the objection, that, according to his doctrine, a Christian who was guilty of wilful sins lost thereby all hopes of salvation. He then maintains, 1Jo 2:3-5, and apparently in allusion to the word γνωσις, knowledge, the favourite term of the Gnostics, that he who boasted of profound knowledge, and at the same time rejected the commandments of Christ, had not a real but only a pretended knowledge; and that in him only the love of God is perfected, τετελειωται, who keeps God’s word. The expression τετελειωται is a term which was used in the schools of the philosophers, and applied to the scholars called esoterici, who had made a considerable progress in the inner school. Now the Gnostics were, in their own opinion, scholars of this description; but since they, whose imaginary system of theology annuls the commands of God, are so far from being perfect that they are not even beginners in the science, St. John very properly refuses to admit their pretensions, and opposes to them others who were perfect in a different way, and who were more justly entitled to the appellation. With respect to the expressions, ‘keeping the commandments of God,’ or ‘not keeping his commandments,’ it must be observed that, when used in a polemical work, they denote, not merely the observance or violation of God’s commands in our own practice, but the teaching of others that they are to be observed or rejected. What St. John says, 1Jo 2:7, 1Jo 2:8, has been already explained in the preceding paragraph.

“The whole of the third chapter, and part of the fourth, is devoted to the doctrine of sanctification, on which I have to make the following remarks. When St. John says, 1Jo 3:7, ‘Let no man deceive you; he who doeth righteousness is righteous,’ he probably intends, not merely to deliver a precept, but to oppose the doctrine of those who asserted that a man, though he sinned, might be righteous in respect to his spiritual soul, because sin proceeded only from the material body. A similar observation may be applied to 1Jo 3:4 : ‘Whosoever committeth sin transgresseth also the law;’ which, considered by itself, appears to be an identical proposition; but when considered as an assertion opposed to the Gnostics, it is far from being superfluous, because, evident as it appears to be, they virtually denied it. From the passage above quoted from the works of Irenaeus, we have seen that they rejected the legal commandments as parts of the Christian religion which were not warranted by the authority of Christ; consequently, they denied that sin was a transgression of the law. Farther, it was consistent with their principles to regard sins as diseases; for they believed in a metempsychosis, and imagined that the souls of men were confined in their present bodies as in a prison, and as a punishment for having offended in the region above. According to this system, the violent and irregular passions of anger, hatred, etc., were tortures for the soul; they were diseases, but not punishable transgressions of the law. I will not assert that all who believed in a transmigration of souls argued in this manner, but some of them certainly did so; and against these it was not superfluous to write, ‘Whosoever committeth sin transgresseth also the law, for sin is the transgression of the law.’

“The love of the brethren, which St. John enforced as a chief commandment, is generally understood of that special love which Christ commanded his disciples to have towards each other. But I rather think that St. John means the love of our neighbor in general, which Christ commanded, as comprehending the half of the law; for this general love St. John might very properly call the love of our brother, since God has created us all, and is our common Father. Besides, as St. John calls Cain, Abel’s brother, he could not intend to signify by this term a person of the same religious sentiments. Nor would it have been consistent with candour to have censured the Gnostics for not having Christian brotherly love towards St. John and other true believers, for in this particular sense they were not brethren; and St. John himself, in his second epistle, 2Jo 1:10, forbids the exercise of Christian brotherly love towards those who teach false doctrines. I believe, therefore, that the brotherly love of which St. John speaks in the third chapter of this epistle, is not confined to that special love which we owe to those who are allied to us by religion, but denotes the love of our neighbor in general. Nor do I except even 1Jo 3:16, where some think that St. John would require too much, if he meant brotherly love in general, or charity toward all men. But are there not certain cases in which it is our duty to hazard and even sacrifice our lives, in order to rescue our neighbor! Is not this duty performed by the soldier? And is it not performed by him who visits those who are infected with contagious diseases? It is true that this is not a duty which every man owes in all cases to his neighbor; but then, on the other hand, is it not a duty which every man owes to his spiritual brother? Nor was it St. John’s design so much to enforce this duty, and to recommend the exercise of it, as to argue from the acknowledgment of this duty in certain cases, to the necessity of performing the less painful duty of supporting our brethren in distress, by a participation of our temporal possessions. But though I believe that in the third chapter St. John speaks of the love of our neighbor in general, I do not mean to affirm that he nowhere understands that special love which Christians owe one to another, of which we meet with an instance in 1Jo 5:1, 1Jo 5:2.

“What St. John says, 1Jo 5:3, that ‘God’s commandments are not grievous,’ appears in the clearest light when we consider it as opposed to the Gnostics, to whom the Divine commandments, as delivered by the apostles, appeared to be too legal.

“St. John declares, 1Jo 1:5, as the message which he had heard from Christ, that ‘God is light, and in him is no darkness at all.’ Now if this proposition had been then as generally admitted as it is at present, there could have been no necessity for declaring it at the very beginning of the epistle, with so much energy, to be the grand message of Christ. We may reasonably infer, therefore, that it was opposed to certain persons who delivered a contrary doctrine. Farther, the words ‘light’ and ‘darkness,’ which are here applied to the Deity in a manner which is not usual in the Bible, remind us of the technical terms used by the Persian Magi, and afterwards by the Manicheans. It is true that in the Bible we meet with the expressions ‘works of the light,’ ‘children of the light,’ ‘to walk in the light,’ and others of the same kind; but in these instances the term ‘light’ is not synonymous with ‘holiness;’ works of the light denoting nothing more than works which no man need be ashamed to perform openly, and in the face of the whole world. This explanation of the word ‘light’ is inapplicable in the proposition ‘God is light;’ because there would be an impropriety in representing God either as fearing or not fearing to act in the face of the whole world. St. John, therefore, uses the term ‘light’ as equivalent to holiness.

“From 1Jo 2:23, where St. John says, that ‘he who denies the Son, rejects also the Father,’ it appears that his adversaries did not deny the Father in positive terms, since the apostle argues only that they virtually did so by denying the Son. Now, the Gnostics did not positively deny the Father of Christ, whom they allowed to be the supreme Being, but then they did not allow that he was the Creator. The terms, therefore, ‘God’ and the ‘Father of Christ,’ though they denote in reality the same person, must not be considered as having precisely the same import; since the adversaries of St. John admitted that the Father of Christ was the supreme Being, and pure light; but denied that the Creator, who is in fact God, was light without darkness.

“4. In some places, especially 1Jo 4:2, 1Jo 4:3, St. John opposes false teachers of another description, namely, those who denied that Christ was come in the flesh. Now they who denied this were not Cerinthians, but another kind of Gnostics, called Docetes. For as, on the one hand, Cerinthus maintained that Jesus was a mere and therefore real man, the Docetes on the other hand contended that he was an incorporeal phantom, in which the Aeon, Christ, or Divine nature, presented itself to mankind. 1Jo 1:1 : ‘Our hands have handled,’ appears likewise to be opposed to this error of the Docetes.

“The doctrines which St. John has delivered in this epistle he has not supported, either by arguments drawn from reason, or by quotations from the Old Testament; for neither of them are necessary, since the bare assertion of an apostle of Christ is sufficient authority. It is true that, in one respect, this epistle has less energy than St. John’s gospel, because in his gospel he warrants his doctrines by the speeches of Christ. But then, on the other hand, St. John declares in this epistle, 1Jo 3:24; 1Jo 4:4; 1Jo 5:14, 1Jo 5:16, that God sent his Spirit to the apostolic Church, and heard their prayers. And it is evident that St. John alludes to the extraordinary gifts of the Holy Ghost, and to the miraculous powers obtained by prayer.

“The style of this epistle being the same with the style of the gospel of John, it is, by that internal mark likewise, denoted to be his writing. In his gospel, John does not content himself with simply affirming or denying a thing; but, to strengthen his affirmation, he denies the contrary. In like manner, to strengthen his denial of a thing, he affirms its contrary. See Joh 1:20; Joh 3:36; Joh 5:22. The same manner of expressing things strongly, is found in this epistle; for example, 1Jo 2:4 : ‘He who saith, I have known him, and doth not keep his commandments, is a liar, and the truth is not in him.’ 1Jo 2:27 : ‘The same unction teacheth you concerning all things, and is truth, and is no lie.’ 1Jo 4:2 : ‘Every spirit which confesseth that Jesus Christ hath come in the flesh, is from God.’ 1Jo 4:3 : ‘And every spirit which doth not confess that Jesus Christ hath come in the flesh, is not from God.’

“In his gospel likewise, John, to express things emphatically, frequently uses the demonstrative pronoun this. Joh 1:19; Αὑτη· ‘This is the testimony.’ Joh 3:19; Αὑτη· ‘This is the condemnation, that light,’ etc. Joh 6:29 : Τουτο· ‘This is the work of God.’ Joh 6:40 : Τουτο· ‘This is the will of him.’ Joh 6:50 : Οὑτος· ‘This is the bread which cometh down from heaven.’ Joh 17:3 : Αὑτη· ‘This is the eternal life.’ In the epistle the same emphatical manner of expression is found, 1Jo 1:5; 1Jo 2:25 : ‘This is the promise.’ 1Jo 3:23 : Αὑτη· ‘This is the commandment.’ 1Jo 5:3 : Αὑτη· ‘This is the love of God.’ 1Jo 5:4 : ‘This is the victory.’ 1Jo 5:6 : Οὑτος· ‘This is he who came by water.’ 1Jo 5:14 : Αὑτη· ‘This is the boldness which we have with him.’

No man, it is hoped, will be so obstinate, perverse, or disingenuous, as to say or insinuate that the man who gives up this text is unsound in the faith; it would be as reasonable to assert, on the other hand, that he who understands the mass of evidence that is against the authenticity of this verse, and who nevertheless will contend for its continuance in the sacred canon, is a Deist in his heart, and endeavors to discredit the truth by mixing it with error and falsehood. Those whose doubts are not removed by the dissertation at the end of his epistle had better read the late Professor Porson’s Answer to Dean Travis, where it is presumed they will receive the fullest satisfaction.
