Follow Old Testament dietary laws?
Should we obey Old Testament dietary laws? (Leviticus 11:1-47 vs. Mark 7:18-19)

Overview of the Question

The dietary laws from the Old Testament, especially Leviticus 11:1–47, have been a point of discussion for those wondering if these regulations remain binding under the New Covenant. On the other side, Mark 7:18–19 appears to teach that all foods are now permissible. Below is an in-depth exploration of these passages, their backgrounds, and how they fit together.


1. Historical and Contextual Background of Old Testament Dietary Laws

In Leviticus 11:1–47, the text details which animals are considered clean and unclean, stipulating precise guidelines for the people of ancient Israel. These dietary parameters were integral to the Mosaic Covenant and served multiple purposes:

1. Covenantal Identity: They set Israelites apart from nations around them (cf. Leviticus 11:44–45).

2. Holiness and Distinction: Old Testament Israel was to be visibly distinct as a holy nation dedicated to the worship of the one true God.

Archaeological findings in regions once inhabited by the Israelites confirm a marked decrease in pig bones, suggesting they seriously followed the command to avoid unclean meats. Such evidence supports the historical authenticity of these practices and the reliability of Old Testament Scripture in reflecting Israel’s unique way of life.


2. Purpose and Function of Leviticus 11

Leviticus 11 introduced distinctions between clean and unclean animals. These categories were part of the broader ceremonial system:

1. Visual Symbol of Purity: By refraining from specific foods, ancient Israel was continually reminded of the necessity of spiritual and moral purity.

2. Illustration of Separation from Sin: Old Testament sacrifices and rituals consistently pointed forward to a coming atonement that would address sin definitively, as anticipated in the prophetic writings (e.g., Isaiah 53).

The Old Testament system—though beneficial for its time—was never intended to be the ultimate source of salvation. Instead, it acted as a tutor and guide until the Messiah arrived (cf. Galatians 3:24).


3. Jesus’ Teachings and Mark 7:18–19

In Mark 7, Jesus responds to concerns about ceremonial washing and food defilement. According to the Berean Standard Bible, Jesus says:

“‘Are you still so dull?’ He asked. ‘Do you not see that whatever enters a man from the outside cannot defile him, because it does not enter his heart but goes into the stomach and then is eliminated?’ (Thus all foods are clean.)” (Mark 7:18–19)

Several points become clear:

1. Internal vs. External Purity: Jesus reorients the focus from external observances to the condition of one’s heart (Mark 7:20–23). He stresses that true defilement arises from sinful desires and actions.

2. Fulfillment of the Law: With His coming, Jesus began to usher in a new covenant reality in which the external symbols and shadows of purity reached fulfillment in Him.

While He did not abolish moral principles or disregard Old Testament Scripture—He thoroughly upheld it (cf. Matthew 5:17)—He also demonstrated that certain ceremonial regulations were now finding their intended completion in His ministry and atoning work.


4. The Transition from Old Covenant to New Covenant

The biblical narrative consistently points to a shift from the specific ceremonial laws of the Mosaic system to the universal new covenant in Christ:

1. Covenant Progression: Hebrews 8–10 explains that the Levitical priesthood and sacrifices foreshadowed Christ’s ultimate sacrifice. Once Christ’s work was done, the ceremonial observances, including dietary laws, were no longer mandatory.

2. Illustration in Acts 10: Peter’s vision of the unclean animals (Acts 10:9–16) highlights the dawning understanding that God declared all foods clean and, symbolically, opened the door of salvation to the Gentiles.

3. Early Church Decrees: At the Jerusalem Council (Acts 15), the apostles clarified there was no requirement for Gentile converts to follow the full Mosaic ceremonial law. Their guidance was grounded in the completed work of Christ.


5. Application in the Early Church and Christian Freedom

As new believers emerged from different cultural backgrounds, questions about food restrictions became common. In Romans 14, Paul emphasizes the importance of conscience and unity in the body of Christ:

1. Conscience and Consideration: Believers have freedom in what they eat, yet are encouraged to avoid causing others to stumble (Romans 14:13–15).

2. All Foods Created by God: In 1 Timothy 4:4, Paul writes, “For every creation of God is good, and nothing that is received with thanksgiving should be rejected.”

This counsel underscores a freedom from Old Testament dietary restrictions, provided such freedom is exercised with love and sensitivity toward others who may feel bound by certain practices.


6. Contemporary Reflections and Health Considerations

Many studies show that certain Old Testament dietary guidelines could yield health benefits—for instance, refraining from specific foods might safeguard against diseases in ancient contexts. Yet from a theological standpoint, dietary laws do not contribute to one’s righteousness or standing before God.

1. Individual Choices: Some Christians choose to follow certain dietary patterns for personal health or as a spiritual discipline, but Scripture no longer mandates them as a covenant requirement.

2. Unity Over Division: Modern believers should not let matters of dietary preference create disunity. The focus is on the gospel of Christ, which transcends national, cultural, and dietary lines.


7. Conclusion: Should We Obey Old Testament Dietary Laws Today?

Based on the entirety of Scripture, we see that the ceremonial laws of ancient Israel—including dietary restrictions—were specific to the Mosaic Covenant. Jesus’ teaching in Mark 7:18–19, Peter’s vision in Acts 10, and the council’s decision in Acts 15 show that these regulations no longer apply as obligatory commandments for salvation or righteousness.

Yet there is no prohibition against following certain dietary guidelines by personal choice—so long as this is not regarded as a requirement for salvation or as a basis for judging others. In essence:

• Christ fulfilled the ceremonial law.

• Salvation is found in Him alone—never in external regulations.

• Believers are free to eat any food with gratitude to God.

As a result, Old Testament dietary laws serve as a historical and theological testimony to God’s holiness, Israel’s distinct calling, and humanity’s need for the redemptive work of the Messiah. Their enduring value lies in pointing us to the greater reality of Christ’s atoning sacrifice and the life-transforming power of the gospel.
