To handle this a little, and to shew you what the apostle here means by naming of the name of Christ: he meaneth not an irreligious naming of that worthy name, nor those that name it irreligiously. This is evident, because he passeth by their manner of naming of it without the least reproof, the which he would not have done had the fault been in their manner of naming of the name of Christ. Now I say, if he intendeth not those that name the name of Christ irreligiously, then, though the exhortation, 'let every one,' seems to extend itself to all, and all manner of persons, that any ways name the name of Christ, yet it is limited by this, to wit, that rightly, religiously, or according to the way of the professors of Christ, name his worthy name. And it must needs be so taken, and that for these reasons:
First, For that, as I said before, the apostle taketh no notice of their manner of naming of his name, so as to reprove any indecency or unseemliness in their naming of him; wherefore he alloweth of the manner of their naming of him.
Secondly, because the apostle's design in this exhortation was, and is, that the naming of the name of Christ might be accompanied with such a life of holiness as might put an additional lustre upon that name whenever named in a religious way; but this cannot be applied to every manner of naming the name of our Lord Jesus Christ. For if a man shall name the name of Christ unduly, or irreligiously, though he shall never so much therewithal depart from iniquity, and be circumspect to the utmost in all civility and morality, yet he answers not the apostle's end, which he seeks by this his exhortation. For,
1. Suppose a man should name the name of Christ vainly, idly, in vain mirth, wantonness, false or vain swearing, or the like, and shall back this, his manner of naming the name of Christ, with all manner of justness and uprightness of life, would this answer the apostle's end in this his exhortation? Verily no; for this manner of naming the name is worthy reprehension; 'Thou shalt not take my name in vain,' or vainly make use thereof: and moral goodness attending the so-naming of the name of Christ will do more hurt than good. (Ex. 20)
2. There is a reproachful and scandalous naming of the name of Christ, such as the Jews and Pharisees did accustom themselves unto, as to call him Jesus, the deceiver; and Christ, in a way of scorn and contempt. Nor were these men quite destitute of that which put a lustre upon their opinions; for, said the Lord Christ himself unto them, 'Ye indeed appear beautiful outward.' (Matt. 23:27)
3. There is such a naming of the name of Christ as to make it a cloak for false and dangerous errors: that men, by the use of that name, and the putting of it upon such errors and delusions, may put off their errors to others the better. 'Many shall come in my name, to wit, with their delusions, presenting them, in my name, to the world, and shall put them off, in my name, to the destruction of the soul. (Matt. 24:5) Now, can any imagine that the apostle should extend his exhortation to such, that they, thus continuing to name the name of Christ, should depart from iniquity. To what end should such be comprehended in this of exhortation of his? to no purpose at all: for the more an erroneous person, or a deceiver of souls, shall back his errors with a life that is morally good, the more mischievous, dangerous, and damnable is that man and his delusions; wherefore such a one is not concerned in this exhortation.
4. There is a naming of the name of Christ magically, and after the manner of exorcism, or, conjuration; as we read in the Acts of the apostles. vagabond Jews, the exorcists, there say, 'We adjure you by Jesus, whom Paul preacheth.' (Acts 19:13-15) Thus they called over them that had evil spirits, the name of the Lord Jesus. But what if these should clothe this, their devilish art, and devilish way, of using or naming of the name of the Lord Jesus, with departing from iniquity, so as to commend their whole life to by-standers, for such: as is morally good: what advantage would Christ, or Paul, or the gospel, get thereby? verily none at all; but rather damage and reproach, as will soon appear to any man's reason, if it be considered that goodness of life, joined to badness of principles is like the devil clothed in white, or Satan transformed into an angel of light. And Paul was grieved in his spirit, when the wench that had a spirit of divination did acknowledge him to be the servant of the most high God, for he knew it would nothing further, or help forward, the Lord's design, but be rather an hinderance thereto. For when witches and devils come once to commend, or make use of the name of Christ, Christ and Paul like it not; therefore Paul's exhortation, which here are presented with by the text, is not extended to any of the four sorts aforenamed, but,
Third, To those upon whom his name is called, they should depart from iniquity. I say those whom God has so far dignified, as to put the name of Christ upon them. (Acts 15:17) And I will add, that apply that name to themselves. And the reason is, because God is now concerned. (ch. 11:26) God has changed thy name from Pagan to Christian, and thou choosest to call thyself by that name, saying, 'I belong to Christ.' Now thou must depart from iniquity, for that notice is taken of thee, both by heaven and earth, that thou art become a disciple, and 'let every one that' so 'nameth the name of Christ,' or that nameth it, being himself by God and himself put under such circumstances as these, 'depart from iniquity.' (1 Peter 4:16)
Fourthly, It is spoken to those that name the name of Christ either in the public or private worship of God, being themselves professed worshippers of him; and the reason is, for that the ordinances, as well as the name of God, is holy, and 'he will be sanctified in them that come nigh him.' (Lev. 10:3) He therefore that approacheth the presence of Christ in prayer, or any other divine appointment, must take heed of regarding 'iniquity in his heart.' (Psa. 66:18) Else the Lord will stop his ears to his prayers, and will shut his eyes, and not take notice of such kind of worship or worshippers.
Fifthly, Those that the apostle in this place exhorts to depart from iniquity are such as have taken unto themselves the boldness to say, that they are in him, abide in him, and consequently are made partakers of the benefits that are in him. 'He that saith he abideth in him, ought himself also to walk, even as he walked.' (1 John 2:6) And the reason is, because Christ is a fruitful root, and a free conveyer of sap into the branches; hence it is written, that 'the trees of the Lord are full of sap.' (Psa. 104:16) So then, he that nameth the name of Christ by way of applying to himself his benefits, and as counting that he is found of God in him, and so abideth, ought himself to walk even as he walked, that he may give proof of what he saith to be true, by bearing forth before men that similitude of righteousness that is in his root and stem: for such as the stock or tree is, such let the branches be, but that cannot be known but by the fruit: 'ye shall know them by their fruit.' (Matt. 7:16) So then, he that thus shall name the name of Christ, let him depart from iniquity: yea, let every such man do so.
