The words of Matthew 5:13, “You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled underfoot,” are often interpreted within Christian contexts. However, to fully grasp their meaning, we must view them as the first-century listeners of Jesus did. Jesus drew upon Torah and Jewish tradition to give this teaching profound moral and spiritual implications.
I have heard dozens of sermons on this verse over the years. Most focus on two aspects of salt: salt as a preservative and salt as a flavor enhancer. Many pastors emphasize how Christians are called to preserve the world from moral decay. Yet, I believe this perspective often misses the deeper significance found in the Torah and Jewish tradition.
In the Torah, salt is a symbol of Covenant and Responsibility. Salt is more than just a seasoning—it’s a symbol of purity, preservation, and covenant. In Leviticus 2:13, God commands, “You shall not omit the salt of your covenant with your God.” Salt represents permanence and incorruptibility, serving as a metaphor for our enduring relationship with God and our responsibility to uphold justice, kindness, and humility.
This cultural and spiritual backdrop is essential for understanding Jesus’ words. In Jesus’ time, salt was abundant and commonly used, particularly by the temple priests. They used salt to purify and preserve meat from sacrificial offerings. After serving its purpose, the salt became defiled and was discarded on roads or pathways. This imagery is crucial: salt, once defiled, could no longer fulfill its sacred purpose.
When Jesus calls us to be the “salt of the earth,” He is reminding us of our covenantal responsibility. Our actions should preserve moral integrity, add meaning to the world, and prevent spiritual and ethical decay. But this responsibility comes with a warning: we must not become defiled by injustice, complacency, or compromise with oppressive systems.
What happens when we lose our ‘saltiness’? The metaphor warns against moral stagnation, a loss of purpose, and alignment with corrupt powers. The followers of Jesus were to fulfill their covenant with God without defiling themselves in the process. Jewish tradition repeatedly highlights this principle. For example, the prophets consistently warned Israel not to abandon their role as a “light unto the nations” (Isaiah 42:6). Today, the same caution applies to us. When we stop striving for justice, speaking out against wrongdoing, or engaging in our communities with integrity, we risk losing our saltiness.
The Old Testament is filled with individuals who preserved their saltiness through righteous action. Abraham’s Advocacy for Sodom and Gomorrah (Genesis 18:23-32) demonstrates the power of intercession and moral courage. Queen Esther’s Courage (Book of Esther) reveals the impact of using one’s position for justice, even at great personal risk. These figures remind us that righteousness isn’t always about grand gestures; it often lies in small, faithful acts—a teacher supporting a struggling student, a volunteer feeding the hungry, or a neighbor showing compassion to the vulnerable.
As followers of Jesus, we must embrace our role as salt to the earth. This aligns with the Jewish principle of Tikkun Olam—the repair of the world. We must ask ourselves: Are we preserving justice and truth in our communities? Are we serving as moral exemplars? Are we ‘salting’ our surroundings with kindness, wisdom, and courage?
In modern American Christianity, it’s clear that many have become defiled through unholy alliances with political power. Some pastors and religious leaders believe they are advancing the Kingdom of God, yet they soil themselves by aligning with empire rather than standing with the oppressed. Jesus rebuked the Herodians for their compromise with power, and His words remain just as relevant today.
Our mission is clear: whether through acts of charity (tzedakah), fighting for social justice, or simply treating others with dignity and respect, we are called to prevent the ‘decay’ of indifference and inaction.
Let this verse serve as a wake-up call: Be the salt. Preserve truth, enhance peace, and keep the covenant. Remain pure in your actions and avoid the contamination of injustice. What may seem like a temporary victory for cultural Christianity could, in reality, be a devastating compromise.
Take action today. Volunteer, advocate, and infuse your corner of the world with purpose and righteousness. Be bold. Be unwavering. The world desperately needs your saltiness now more than ever.
