For in Christ Jesus. The reason why he is crucified to the world, and the world to him, is, that in Christ, to whom he is spiritually united, nothing but a new creature is of any avail. Everything else must be dismissed, must perish. I refer to those things which hinder the renewing of the Spirit. "If any man be in Christ" says he, "let him be a new creature." (2-Corinthians 5:17.) That is, if any man wishes to be considered as belonging to the kingdom of Christ, let him be created anew by the Spirit of God; let him not live any longer to himself or to the world, but let him be raised up to "newness of life." (Romans 6:4.) His reasons for concluding that neither circumcision nor uncircumcision is of any importance, have been already considered. The truth of the gospel swallows up, and brings to nought, all the shadows of the law.

For in Christ Jesus - In his religion; see the note at Galatians 5:6.
But a new creature - The fact that a man is created anew, or born again, constitutes the real difference between him and other people. This is what Christ requires; this is the distinction which he designs to make. It is not by conformity to certain rites and customs that a man is to be accepted; it is not by elevated rank, or by wealth, or beauty, or blood; it is not by the color of the complexion; but the grand inquiry is, whether a man is born again, and is in fact a new creature in Christ Jesus; see the note at 2-Corinthians 5:17, for an explanation of the phrase "a new creature."

In Christ Jesus - Under the dispensation of the Gospel, of which he is head and supreme, neither circumcision - nothing that the Jew can boast of, nothing that the Gentile can call excellent, availeth any thing - can in the least contribute to the salvation of the soul.
But a new creature - Αλλα καινη κτισις· But a new creation; not a new creature merely, (for this might be restrained to any new power or faculty), but a total renewal of the whole man, of all the powers and passions of the soul; and as creation could not be effected but by the power of the Almighty, so this change cannot be effected but by the same energy; no circumcision can do this; only the power that made the man at first can new make him. See the note on 1-Corinthians 7:19, and on 2-Corinthians 5:17 (note).

For in Christ Jesus,.... These words are omitted in the Syriac and Ethiopic versions; See Gill on Galatians 5:6, 1-Corinthians 7:19, they contain a reason why the apostle gloried in a crucified Christ, and looked upon the world as dead to him, and he to that, in every state of it; particularly as it may design "the worldly sanctuary" of the Jews, and all the rites and ceremonies appertaining to it; and among the rest
circumcision, which availeth not anything; neither as a command, type, or privilege; or in the business of salvation, being abolished by Christ:
nor uncircumcision; being now no bar to the Gospel, Gospel ordinances, or a Gospel church state; or to any of the blessings of the everlasting covenant, which come upon the uncircumcision, as well as the circumcision. But to apply these words to baptism and non-baptism is a wretched perversion, and making a very ill use of them, whereby the minds of men are worked up to an indifference to a Christian institution; for though baptism is of no avail in the business of salvation, yet it cannot be said of it, as of circumcision, that it avails not anything as a command; for it is a standing ordinance of Christ; or as an emblem and sign, for it is significative of the death and burial, and resurrection of Christ; or as a privilege, for it is of use to lead the faith of God's people to his blood and righteousness for pardon and justification; for he that believes, and is baptized, shall be saved; and it is necessary to church communion: and, on the other hand, it cannot be said that non-baptism avails not; it is a bar to church fellowship; and a neglect of baptism in those who are the proper subjects of it, is resented by Christ, and is a rejecting of the counsel of God against themselves; which was the case of the Pharisees, in the time of John the Baptist:
but a new creature. The phrase is Rabbinical; See Gill on 2-Corinthians 5:17 by which is meant, not a new creation of a man, as a man, of the members of his body, or of the faculties of his soul; nor of an external reformation, or a walking in newness of life, which is the fruit and effect of this new creation work; but an internal principle of grace, a good work of God begun in the soul, called the hidden man of the heart, the new man, Christ formed in us, of which faith that works by love is a part: this is called a "creature", and so not of man, but God; for none can create but himself; and in which work man is purely passive, as the heavens and the earth were in their creation: it is "but" a creature, and therefore needs divine support, fresh strength from God, and frequent supplies of grace to maintain and preserve it; nor is it to be trusted in, but the grace which is in Christ, from whence it comes, and by which it is secured. This is a "new" creature, in opposition to the old man; and because it is a principle in man, which never was there before; it consists of a new heart and spirit, of new eyes, ears, hands, and feet, expressive of new principles and actions, of new light, life, love, desires, joys, comforts, and duties: now this is of avail; it is a branch of the new covenant of grace, which God has therein promised to bestow on his people; it is an evidence of interest in Christ, the new and living way to the Father, and eternal life; such are newborn babes, regenerated persons, and have a right and meetness for the kingdom of God; shall possess the new Jerusalem, shall dwell in the new heavens and new earth; they are called by the Lord's new name, the adopted children of God; and have a new song put into their mouths, which none but redeemed and newborn souls can sing; and shall drink the new wine of endless joys and everlasting pleasures with Christ, in his Father's kingdom. These words are said to be taken out of the Apocalypse of Moses, a spurious book, but without any foundation.

availeth--The oldest manuscripts read, "is" (compare Galatians 5:6). Not only are they of no avail, but they are nothing. So far are they from being matter for "glorying," that they are "nothing." But Christ's cross is "all in all," as a subject for glorying, in "the new creature" (Ephesians 2:10, Ephesians 2:15-16).
new creature-- (2-Corinthians 5:17). A transformation by the renewal of the mind (Romans 12:2).

In Christ Jesus. See note on Galatians 5:6. Circumcision in itself is a matter of indifference. To be a new creature, neither Jew nor Gentile, but a child of God is essential.
This rule. The one just named in Galatians 6:15. A benediction is pronounced upon all such.
And upon the Israel of God. Rather, Even upon, etc. The Greek word often means even, and does here, as the Israel of God does not differ from those who follow "this rule."
From henceforth let no man trouble me. Dispute my apostolic authority.
I bear in my body the marks, etc. He bore on his body too many evidence of what he had suffered for Christ. As slaves were often branded by their master's name, so he had the brand of Christ upon him in his scars. Compare 2-Corinthians 11:24-25.
Brethren. This is his parting benediction. It rests not upon the flesh against which he had warned them, but upon the highest part of their being, the spirit.

For neither circumcision is anything, nor uncircumcision - Neither of these is of any account. But a new creation - Whereby all things in us become new.
