Circumcisions or Christ- Gal. 5:2-6

I)The Full Weight of Paul’s Apostolic Authority (V. 1)

The Apostle Paul opens with an authoritative appeal when he says:

“Behold I, Paul, say to you…” — Galatians 5:2 LSB

Rarely does Paul begin a sentence with “I, Paul...”

2 Corinthians 10:1 “Now I, Paul, myself plead with you by the gentleness and forbearance of Christ—I who am humble when face-to-face with you, but courageous toward you when absent!”

Philemon 19 “I, Paul, am writing this with my own hand, I will repay it (not to mention to you that you owe to me even your own self as well).”

1 Thessalonians 2:18 “For we wanted to come to you—I, Paul, more than once—and yet Satan hindered us.”

Colossians 1:23 “if indeed you continue in the faith firmly grounded and steadfast, and not moved away from the hope of the gospel, which you have heard, which was proclaimed in all creation under heaven, and of which I, Paul, was made a minister.”

Ephesians 3:1 “For this reason I, Paul, the prisoner of Christ Jesus on behalf of you Gentiles—”

Here in verse 2, this is important because Paul has now finished laying out the doctrine of the gospel—a gospel he received not from man, but through the revelation of Jesus Christ.

As he said earlier in this letter:

“For I would have you know, brothers, that the gospel which was proclaimed by me is not according to man. For I neither received it from man, nor was I taught it, but I received it through a revelation of Jesus Christ.” — Galatians 1:11–12

In other words, Paul is saying:

“Now that I have made abundantly clear how a person is saved, what justification by faith truly means, and the freedom that is found in Christ—what are you going to do with it?”

Paul has spent chapters 2:16-5:1 defending the doctrine of justification by faith alone apart from works of the Law.

But now he begins moving from doctrine to application—from what Christians are to believe to how Christians are to live.

What follows is the practical outworking of the gospel in the believer’s life.

There is no turning back now—only moving forward in obedience to the truth that has been revealed.

And the stakes could not be higher.

Paul understands that to abandon the gospel of grace is not a small theological error, but a soul-damning one.

That is why he speaks here with the full weight of his apostolic authority.

As Baugh says,

“The staccato style of the Greek and of the thoughts in Galatians 5:1–6 is notably abrupt and direct. There is no luxurious, unfolding periodic style.… Instead, Galatians 5:1–6 is unvarnished, direct, heartfelt appeal, warning, and testimony, because the audience’s actions carry the gravest of consequences.”

This is not merely Paul’s opinion. This is the authoritative Word of God delivered through Christ’s appointed apostle, and with it comes an ultimatum:

“How then will you live in light of the truth that has been given to you?”

And the weight of this ultimatum is immediately seen in what follows:

“....that if you receive circumcision, Christ will be of no benefit to you.” — Galatians 5:2 LSB

The line in the sand has now been drawn.

There are only two paths being presented: justification by the works of the Law or justification by faith in Christ alone. And only one of those paths contains salvation and eternal benefit.

It is here, for the first time in the letter, that Paul directly confronts the issue of circumcision itself.

Earlier, in Galatians 2:3–5, Paul alluded to the matter through Titus, where false brothers sought to compel circumcision in order to spy out and undermine Christian liberty:

“But not even Titus, who was with me, though he was a Greek, was compelled to be circumcised. But it was because of the false brothers secretly brought in, who sneaked in to spy out our freedom which we have in Christ Jesus in order to enslave us.” — Galatians 2:3–4 LSB

As I pointed out to you last week, the “yoke of slavery” Paul had in mind was circumcision—as Peter himself referenced during the Jerusalem Council:

“Now therefore why do you put God to the test by placing upon the neck of the disciples a yoke which neither our fathers nor we have been able to bear?” — Acts 15:10 LSB

And so what Paul had previously alluded to is now made unmistakably plain for us here: circumcision is the issue.

As we have already seen throughout Galatians, these two systems are completely opposed to one another. Faith came prior to the Law, and even circumcision itself came years after the promise given to Abraham in Genesis 12.

Notice carefully the words Paul uses here: “receive circumcision” and “Christ will be of no benefit to you.”

These phrases carry tremendous weight and even point us forward to an eschatological reality—to the final judgment itself.

And so the Galatian believers therefore have a choice to make:

Will they receive Christ and all the benefits found in Him—eternal life, forgiveness, righteousness, adoption, and rest from the burden of the Law?

Or will they receive circumcision as a means of justification and place themselves again under condemnation and guilt?

Paul makes this same argument in Romans 2. Circumcision is of no value (and it is the same Greek word being used) if one seeks justification through it and yet fails to keep the whole Law perfectly.

As Paul writes:

“For indeed circumcision is of value if you practice the Law; but if you are a transgressor of the Law, your circumcision has become uncircumcision.” — Romans 2:25 LSB

In other words, if a person chooses the path of Law-keeping for justification, then perfect obedience is required.

One failure makes the person guilty before God.

And that is Paul’s warning to the Galatians: if you seek righteousness through circumcision and Law-keeping, then you are abandoning Christ as your only hope of salvation.

You’ve forfeited every spiritual blessing,

There is no “I’ll take a half-Christ for 500, Alex.”

It is Jesus or northing.

“Whoever wants to have a half-Christ loses the whole.” (Calvin)
