At first glance, Jesus seems to be saying that every disciple must observe every detail of the Mosaic Law exactly as it was practiced in first-century Judaism. Yet the rest of the New Testament makes clear that this is not what the Church understood Him to mean.
The first Christians were Jews. They naturally continued many Jewish practices such as circumcision, dietary regulations, and observance of ritual purity laws. The great question arose when Gentiles began entering the Church in large numbers through the ministry of Saint Paul and others: must Gentile Christians become Jews in order to follow Christ?
This issue was settled at the Council of Jerusalem. Under the leadership of Saint Peter, the apostles concluded that Gentile converts were not required to be circumcised or observe the full Mosaic code. The ceremonial and civil aspects found their completion in Christ. The sacrifices pointed to His sacrifice. The Temple pointed to His Body. Ritual purity pointed to the holiness He would bestow through the Holy Spirit.
But the moral law, however, was not abolished. In fact, Jesus deepened it:
- “You shall not kill” became a prohibition against hatred.
- “You shall not commit adultery” became a call to purity of heart.
- “Love your neighbor” expanded into “Love your enemies.”
Jesus was not lowering the standard but raising it from external compliance to interior transformation. Saint Augustine famously observed that Christ transformed the Law from something written on stone tablets into something written on human hearts.
The Lord’s concern was not whether Gentile Christians kept kosher guidelines or observed the ritual prescriptions of ancient Israel. Rather, He asks whether His disciples allow His teaching to shape their hearts and whether they help others do the same.
The true fulfillment of this verse is not found in legalism but in holiness. Christ calls His followers beyond mere rule-keeping to a life in which God’s commandments are embraced as expressions of love. The one who lives that love and teaches it by word and example participates already in the life of the Kingdom and, according to Jesus, “will be called greatest in the Kingdom of heaven.”
