Why are some OT laws still needed?
Acts 15:7–9 – If God supposedly made no distinction between Jews and Gentiles, why do some Old Testament laws still appear necessary in the letter?

I. Historical Context of Acts 15

Acts 15 describes a critical turning point in the early community of believers. Certain Jewish believers were teaching that Gentiles must be circumcised and required to keep the Law of Moses in order to be saved (see Acts 15:1). In response, the apostles and elders gathered in Jerusalem to discuss whether non-Jewish believers should submit to every aspect of the Old Testament Law.

Peter testified to how God made no distinction between Jew and Gentile, focusing on Acts 15:7–9:

“After much discussion, Peter got up and said to them, ‘Brothers, you know that in the early days God made a choice among you that the Gentiles would hear from my lips the message of the gospel and believe. And God, who knows the heart, showed His approval by giving the Holy Spirit to them, just as He did to us. He made no distinction between us and them, for He cleansed their hearts by faith.’”

Yet, at the end of the discussion, the Council still instructed Gentiles to “abstain from food sacrificed to idols, from sexual immorality, from the meat of strangled animals, and from blood” (Acts 15:29). Many ask why, if God has removed the distinction between Jewish and Gentile believers, certain laws from the Old Testament appear retained.


II. The Larger Issue: Salvation and Fellowship

Peter’s statement that God makes “no distinction” between Jews and Gentiles addresses salvation. The Holy Spirit fell on Gentiles in the same way He fell on Jewish believers (Acts 10:44–46, Acts 15:8), demonstrating that Gentiles were accepted by God solely through faith in Christ and not by adherence to the full scope of ceremonial, dietary, and sacrificial laws.

The directives found in the letter sent from Jerusalem (Acts 15:23–29) specifically address matters of fellowship and moral living, rather than the comprehensive Mosaic code as a system of earning God’s favor. Throughout the New Testament, there is a clear message that salvation is by grace through faith in Christ alone (Ephesians 2:8–9), and not by works of the Law (see also Galatians 2:16).


III. Understanding the Retained Laws

1. Moral Concerns vs. Ceremonial Observances

Many Old Testament laws fall into categories—moral, ceremonial, and civil. The letter in Acts 15 retains certain rules mainly tied to moral and communal behavior. Sexual immorality (Acts 15:29) is consistently condemned throughout Scripture as it violates God’s moral standards (see Leviticus 18:6–23; Romans 1:24–27; 1 Corinthians 6:18).

2. Table Fellowship and Idolatry

The early Jewish believers were deeply concerned about idolatry and the practices associated with pagan worship. Abstaining from food offered to idols and from blood connects to the longstanding Jewish call to separate oneself from idolatrous activity (see Leviticus 17:10–12; 1 Corinthians 8:1–13).

For the Jewish-Gentile community to share meals and sacramental fellowship (such as the Lord’s Supper) in unity, guidelines had to be clarified. These specific commands allowed Jewish and Gentile believers to sit together and eat without the unintentional offense that deeply-rooted cultural concerns might cause.

3. Strangled Meat and Respect for Life

In the Old Testament, blood represented life (Leviticus 17:11). Avoiding the blood of strangled animals reflects the broader biblical principle that life (symbolized by blood) is precious. While believers in Jesus are not under an obligation to follow every dietary restriction found under the Mosaic Covenant, the Jerusalem Council deemed it wise for Gentile believers to respect Jewish sensitivities regarding blood to maintain peaceful fellowship.


IV. Consistent Teaching on Unity and Distinction

1. Heart of the Gospel: Grace

God shows no distinction in granting grace (Romans 10:12 says, “For there is no difference between Jew and Greek…”). The core truth is that believers from every background are redeemed the same way—through faith in Christ.

2. Practical Harmony in Community

The Jerusalem Council’s guidelines in Acts 15 do not reflect a reversal of God accepting Gentiles. Instead, they preserve unity among diverse groups in the early church. Archaeological and historical records indicate that the early believers met in house gatherings shared by both Jewish and Gentile members. Observing a few key cultural and ethical precepts smoothed the way for shared worship and minimized unnecessary stumbling blocks.

3. Ongoing Relevance of the Moral Law

Both Old and New Testament teachings uphold universal moral tenets, such as the prohibition against sexual immorality and idolatry (1 Thessalonians 4:3–8; 1 John 5:21). These are not relics from a past system but remain expressions of God’s character and design for human relationships.


V. How the Old Testament Commandments and New Testament Grace Coexist

1. Law as a Tutor

Galatians 3:24 indicates that “the Law was our guardian to lead us to Christ.” Its primary function was to highlight human sinfulness and point to the need for a perfect Savior. Now that Christ has fulfilled the Law, believers are no longer under its ceremonial or civil burdens (Matthew 5:17–18). Yet the moral dimensions of the Mosaic Law, reflecting God’s holiness, stand as timeless principles applicable to all believers.

2. Freedom from Legalism

The Council’s brief instructions do not place the Gentiles under the entire Mosaic system, but offer guidelines for holy living and respectful fellowship. In the same chapter, the apostles emphasize that they did not wish to “burden” the Gentiles (Acts 15:28). This demonstrates a new paradigm: life in the Spirit rather than rote adherence to regulations (Romans 7:6).

3. Christ’s Fulfillment and the Believer’s Transformation

As believers live under Christ’s New Covenant, the Holy Spirit enables them to fulfill the essence of the Law through love (Romans 13:8–10). This does not mean ignoring the Mosaic revelation; it means recognizing the Law’s underlying principles of holiness, then applying them through the transformative power of the Spirit.


VI. Practical Lessons and Application

1. Unity in Diversity

The early church balanced differences in cultural and religious backgrounds by focusing on the shared belief in Christ’s death and resurrection (1 Corinthians 15:3–4). Today, respecting legitimate differences in worship styles or cultural approaches—while adhering to core biblical truths—fosters unity among believers.

2. Avoiding Stumbling Blocks

The Council’s guidelines serve as a model for believers when interacting with those of different cultural or religious sensitivities (Romans 14:13–15). Sensitivity and love should guide our liberties, so we do not hinder others from embracing the faith or worshiping freely.

3. Moral Integrity for All

The behavioral commands, such as refrain from sexual immorality, remind believers of the consistent moral standards that transcend cultural distinctions. Today’s context might differ, but holiness remains central to God’s will for believers.

4. Christ at the Center

Ultimately, the letter in Acts 15 underscores that true acceptance comes through faith in Jesus Christ, who unifies believers of all nations and ethnicities (Galatians 3:28). Any commands retained or repeated in the New Testament spotlight the moral core that reflects God’s enduring character.


Conclusion

Acts 15:7–9 demonstrates that God placed no barrier to salvation between Jews and Gentiles. This truth stands firm: acceptance by God comes through faith in Christ alone. The guidelines retained in the Jerusalem letter helped early believers navigate cultural sensitivities, idolatry concerns, and moral imperatives.

These directives should be understood not as a return to a rigid legal system but as protective measures for unity and holiness. Taken in the broader teaching of the New Testament, they uphold the transforming power of grace while honoring God’s moral nature and maintaining fellowship across cultural lines.
