The Great Commandment

 The Great Commandment Matthew 22:37-40

The passage of Matthew 22:37–40, often referred to as the "Great Commandment," represents the theological apex of Jesus’ teaching regarding the Mosaic Law. When Jesus declares that "all the Law and the Prophets hang on these two commandments," He is asserting that the entirety of the Old Testament—its moral, civil, and ceremonial requirements—finds its ultimate purpose and interpretive key in the dual mandate of love for God and love for neighbor.

In the context of first-century Jewish thought, the "Law and the Prophets" served as the comprehensive designation for the Hebrew Scriptures. By distilling these into two commands, Jesus does not suggest that the other commandments are abolished; rather, He provides a hierarchy of values that explains why the law exists. The first commandment, "Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind," is drawn from the Shema in Deuteronomy 6:5. This command establishes that the fundamental orientation of a human life must be toward the Creator. Because God is the source of all morality, any act of obedience not rooted in love for Him is incomplete or hollow.

The second commandment, "Thou shalt love thy neighbour as thyself," originates in Leviticus 19:18. Jesus links this to the first, arguing that the two are inseparable. The logic behind this synthesis is that human beings are created in the imago Dei (image of God). Therefore, one cannot authentically love the Creator while simultaneously mistreating or disregarding those who bear His image. This creates a unified ethical framework: love for God provides the vertical motivation, while love for neighbor provides the horizontal application. Every specific statute in the Law—whether regarding justice, worship, or social conduct—is simply a practical expression of how to love God and neighbor in specific circumstances.

The "hanging" of the law on these two pillars suggests that the entire structure of biblical revelation is supported by these principles. If one removes the foundation of love, the specific laws lose their moral coherence and become mere legalism. Thus, Jesus teaches that the heart of the law is not a list of prohibitions, but a relationship-driven ethic that transforms the individual from the inside out.

An Example:

The parable of the Good Samaritan, recorded in Luke 10:25–37, serves as the definitive practical application of the second Great Commandment: "Thou shalt love thy neighbour as thyself." While the Pharisees and legal experts of Jesus' day often sought to define the boundaries of "neighbor" to limit their obligations, Jesus used this narrative to dismantle those barriers entirely.

In the historical context of first-century Judea, the relationship between Jews and Samaritans was defined by deep-seated ethnic and religious animosity. By making a Samaritan the hero of the story, Jesus shocked his audience, forcing them to redefine "neighbor" not by social, religious, or ethnic proximity, but by the presence of human need. The priest and the Levite, who passed by the wounded man, likely prioritized ritual purity laws—fearing that contact with a corpse or blood would render them unfit for temple service—over the immediate moral imperative of mercy.

The Samaritan, however, demonstrates that love is an active, sacrificial, and costly endeavor. He does not merely feel pity; he "had compassion," which in the Greek text implies a visceral, gut-level response that compels action. He provides first aid, transports the victim to an inn, pays for his care, and promises to cover any additional expenses. This illustrates that loving one's neighbor as oneself requires the suspension of self-interest and the crossing of social boundaries to serve those whom society might deem "unlovable" or "other."

Jesus’ conclusion—"Go, and do thou likewise"—transforms the abstract command to "love thy neighbor" into a concrete, radical lifestyle. It suggests that the "Law and the Prophets" are fulfilled when one recognizes that every person in need is a neighbor, regardless of their background or status. As noted by biblical scholars, this parable shifts the question from "Who is my neighbor?" (an attempt to limit obligation) to "To whom can I be a neighbor?" (a call to universal responsibility).
