Galatians – A Powerful Warning Against Legalism and Returning to Shadows

Galatians – A Powerful Warning Against Legalism and Returning to Shadows

The book of Galatians provides one of the strongest New Testament parallels to the error of imposing Old Covenant practices like mandatory seventh-day Sabbath keeping on New Covenant believers. Paul wrote it to confront “Judaizers” who taught that Gentile Christians must observe the Mosaic Law (including circumcision, festivals, and holy days) to be truly accepted by God.

Key passages that directly apply:

Galatians 4:9–10

But now that you know God—or rather are known by God—how is it that you are turning back to those weak and miserable forces? Do you wish to be enslaved by them all over again? You are observing special days and months and seasons and years!

Paul equates turning back to mandatory observance of days (including Sabbaths) with returning to spiritual slavery under “weak and miserable forces.” This is a direct rebuke of any system that makes Old Covenant calendar-keeping a requirement for Christians.

Galatians 5:1–4

It is for freedom that Christ has set us free. Stand firm, then, and do not let yourselves be burdened again by a yoke of slavery… You who are trying to be justified by the law have been alienated from Christ; you have fallen away from grace.

Making Sabbath observance (or any Old Covenant sign) a “test commandment” for salvation, fellowship, or future inheritance is precisely the kind of legalism Paul condemns. It shifts trust from Christ’s finished work to human performance.

Galatians 3:24–25 The law (including the Sabbath command) was a guardian or tutor to lead us to Christ. “Now that this faith has come, we are no longer under a guardian.” 

 

Galatians shows that legalism is not just a minor doctrinal difference — it is a different gospel (Gal. 1:6–9) that nullifies grace and severs people from Christ. 

Hebrews 3–4 develops a sustained argument that the ultimate “rest” God offers is far greater than the weekly Sabbath or even the physical Promised Land 

Hebrews 4 – The Spiritual “Sabbath Rest” Fulfilled in Christ — a present reality of resting from our own works by faith in Christ. God’s own rest began after creation (Heb. 4:4). 

 

Colossians 2:16–17 – Shadows vs. Substance … weekly Sabbath explicitly called a shadow; do not let anyone judge you by it. 

 

Romans 14:5–6 – Liberty Over Disputable Matters … days are matters of conscience, not grounds for judgment.

Israel under Joshua never fully entered that rest because of unbelief.
Therefore, “there remains a Sabbath-rest [sabbatismos] for the people of God” (Heb. 4:9).

This sabbatismos is not another weekly ritual but a permanent state of rest: “For anyone who has entered God’s rest also rests from their own works, just as God did from his” (Heb. 4:10). It is the present spiritual reality of ceasing from self-justifying efforts and trusting completely in Christ’s finished work. Believers enter this rest the moment they believe.

Colossians 2:16–17 – Shadows vs. Substance

7Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day. These are a shadow of the things that were to come; the reality, however, is found in Christ.” (Col. 2:16–17)

The weekly Sabbath is explicitly listed among the Old Covenant shadows. Once the substance (Christ) has come, believers are not to let anyone judge them regarding these days.

Romans 14:5–6 – Liberty Over Disputable Matters

The apostle Paul applies this same principle practically in the church:

8One person considers one day more sacred than another; another considers every day alike. Each of them should be fully convinced in their own mind. Whoever regards one day as special does so to the Lord.”

Galatians – The Danger of Legalism

Paul warns that returning to mandatory observance of days is a return to slavery and a fall from grace. Any teaching that makes Sabbath-keeping a test of righteousness or a requirement for salvation mirrors the exact error he confronted in the early church.

Grace, Not Legalism — The True Sabbath Rest of the New Covenant

The New Covenant does not abolish the principle of Sabbath rest; it fulfills and elevates it entirely in Christ. The weekly seventh-day observance was always a temporary shadow — a gracious tutor meant to lead God’s people to the greater reality of ceasing from all self-reliant works and resting wholly in the finished, once-for-all work of Jesus (Hebrews 4:9–10; Colossians 2:16–17; Romans 14:5–6).

Hebrews 4 reveals this rest as a present spiritual reality that every believer enters the moment they trust Christ alone. Colossians 2 declares the old shadows obsolete. Romans 14 treats observance of days as a disputable matter of Christian liberty. Galatians powerfully warns that imposing such days as a requirement is a return to slavery and a fall from grace (Galatians 4:9–10; 5:1–4).

Armstrongism’s insistence that seventh-day Sabbath keeping remains a binding “test commandment” for Christians today — and will be strictly enforced in the Kingdom — is a serious theological error that parallels the legalism Paul confronted in Galatians. By making a specific day a requirement for acceptance with God or for future salvation, it:

• Confuses the shadow with the substance, living as though Christ’s finished work never fully arrived.
• Undermines the glorious superiority of the New Covenant (Hebrews 8:6–13), which operates by better promises, a better High Priest, and the law written on the heart rather than external rituals.
• Reimposes the very legalism the apostles decisively rejected (Acts 15; Galatians 1–5; Colossians 2:20–23; Romans 14). Turning any Old Covenant sign into a test of righteousness directly contradicts justification by grace through faith alone and risks alienating people from Christ.
• Diminishes the liberating power of the gospel, exchanging the rest we receive as a free gift for a system of ongoing performance, fear, judgment of others, and division.

In the coming Kingdom and the eternal state, the focus will not be a return to Mosaic calendar-keeping, but unhindered worship of the Lamb in the fullness of His glory (Revelation 21–22). The ultimate Sabbath will be perfect, unending rest — not because we keep a day perfectly, but because we are perfectly kept by grace in the presence of our Savior. The “rest” will be complete — no more sin, no more curse, no more striving. Every day will be a Sabbath in the fullest sense because we will forever rest in the presence of the One who is our Sabbath.

This is the heart of the New Covenant: we do not earn rest through commandment-keeping; we enter rest by grace through faith. Jesus’ invitation remains open to every weary soul:

Come to me, all you who are weary and burdened, and I will give you rest. Take my yoke upon you and learn from me… and you will find rest for your souls. (Matthew 11:28–29)

That is the true Sabbath rest of the New Covenant — and it is infinitely better than any weekly ritual could ever be.
