The Law of Moses, often referred to as the body of laws delivered through Moses, encompasses a wide range of instructions that are not in opposition to grace and truth but are layered upon by them, working together in agreement as part of a continuing revelation. This law, sometimes called the civil law of Israel, originally had no sacrifices, but later came to include both civil and ceremonial components, which are intermingled. As noted in Luke 2:22-24, the Law of Moses is also termed the Law of the Lord, indicating that all biblical law, including ceremonies and rituals, originates from God, with Moses merely serving as the deliverer. Despite common perceptions, the Law of Moses is not confined to a lesser status compared to the Ten Commandments; it is equally part of God's law, supporting and extending the foundational principles of the Commandments. Malachi 4:4 urges remembrance of the Law of Moses, including statutes and judgments, even in end-time contexts, emphasizing its enduring relevance. This law is not abolished but remains binding in its spirit, as Jesus affirmed in Matthew 5, stating that not one jot or tittle will pass from the law until all is fulfilled. Specific aspects of the Law of Moses, such as ceremonial laws involving sacrifices and washings, have been set aside under the New Covenant, as evidenced in Hebrews 9:8-10 and Hebrews 10:18, where these practices are described as temporary impositions until the time of reformation, replaced by the superior sacrifice of Jesus Christ. However, the civil aspects, which guide community life and regulate specific behaviors, continue to apply. Examples from Leviticus and Exodus, such as laws against defrauding neighbors, talebearing, and afflicting widows or orphans, illustrate ongoing obligations to uphold justice and respect, demonstrating that these laws are extensions of the Ten Commandments. The Jerusalem Council in Acts 15 addressed whether Gentiles must keep ceremonial aspects of the Law of Moses for salvation, concluding that only specific laws, such as abstaining from idol pollution, fornication, strangled things, and blood, were immediately required, with the expectation that further instruction would be received through synagogue teachings on the Sabbath. This indicates that the apostles did not believe in wholesale dismissal of the Law of Moses but recognized its continued relevance, particularly in civil matters, applying equally to Israelites and strangers alike, as stated in Exodus 12. Furthermore, the Law of Moses served as the constitution for the nation of Israel, a role akin to foundational legal documents in modern contexts, underscoring that the church lacks authority to abolish it entirely, only addressing ceremonial aspects related to devotion and justification. Jesus magnified the law, broadening its application from specific letter to spiritual intent, as seen in laws like Leviticus 19:19 regarding mixed materials, which expand to principles of maintaining quality and purity in broader applications. Thus, while certain ceremonial practices are not physically required, the essence and intent of the Law of Moses remain vital for guiding conduct and community life.

Just as parents send children out with specific cautions while all household rules still apply, the Council of Jerusalem in Acts 15 addressed whether Gentile converts had to follow Jewish customs like circumcision to be saved. Certain Judean believers insisted on circumcision according to the Law of Moses, but the apostle Paul and Barnabas disputed this and appealed to the apostles in Jerusalem. The apostle Peter testified that God had already accepted Gentiles—shown in the conversion of Cornelius the Centurion—by giving them the Holy Spirit and purifying their hearts through faith, not through ritual law. James affirmed this using the prophecy of Book of Amos, concluding that salvation is by grace through Jesus Christ for both Jews and Gentiles. The council therefore rejected imposing the heavy burden of accumulated Jewish traditions, asking Gentile believers only to avoid idolatry-related food, sexual immorality, and blood—practices common in pagan culture that would disrupt fellowship. Overall, the decision affirmed that justification comes through grace and faith rather than works like circumcision, while God's moral commandments still guide holy living and unity among believers
