Bible and the Concept of "Unclean"

The book of Leviticus in the Bible extensively uses the term "unclean," emphasizing the distinction between "clean" and "unclean" states. This distinction applies not only to animals, objects, food, and clothing but also to people. In the context of the Mosaic Law, something was considered "unclean" if it was unfit for use in worshiping God. The designation of being "clean" or "unclean" was primarily related to ceremonial practices within corporate worship.

For instance, certain animals, like pigs, were deemed unclean and therefore not suitable for use in sacrifices (Leviticus 5:2). Additionally, actions such as touching a dead body would render a person unclean, temporarily disqualifying them from participating in worship ceremonies (Leviticus 5:3). Leviticus 10:10 teaches believers to discern between the holy and the common, as well as between the clean and the unclean. This command reflects not only physical actions but also one's spiritual condition.

In Jewish dietary laws, certain foods were considered unclean and forbidden for consumption. Examples include pork, specific fish, and certain birds. Moreover, various circumstances could render a person unclean, such as a skin infection that would make them unfit to be present at the tabernacle or even within the community (Leviticus 13:3). Even a house with certain types of mold would be deemed unclean. Furthermore, women experienced a period of uncleanness following childbirth. On holy days, couples were restricted from engaging in sexual activity due to the release of semen making them unclean until evening (Leviticus 15:18).

While there were numerous circumstances that could make an individual, animal, or object unclean, most of these laws pertained to activities that would disqualify a person or animal in relation to offerings at the tabernacle. Animals offered as sacrifices needed to be without defect, and the person offering the sacrifice had to be ceremonially clean, complying with the Law and approaching God with reverence.

In the New Testament, Jesus used the concept of being "clean" to illustrate the importance of holiness. In Luke 11:39–41, Jesus rebukes the Pharisees, saying, "Now then, you Pharisees clean the outside of the cup and dish, but inside you are full of greed and wickedness. You foolish people! Did not the one who made the outside make the inside also? But now as for what is inside you—be generous to the poor, and everything will be clean for you."

The concepts of clean and unclean were deeply ingrained in the lives of those living under the Old Testament Law. God called His people to separate themselves from the impurities of the world, emphasizing purity in both physical and spiritual aspects. These principles of cleanliness extend into the New Testament as well, where believers are encouraged to live lives that are pure (2 Corinthians 6:17) and strive for holiness, aligning their conduct with their calling (Colossians 1:10).

Why This Matters

Understanding the concept of clean and unclean is crucial for believers seeking to comprehend the biblical teachings found in both the Old and New Testaments. Although some of these regulations may appear foreign or even irrelevant to modern-day Christians, they offer valuable insights into God's character and His desire for a holy people. Exploring these concepts helps us appreciate the significance of Jesus' teachings on spiritual purity and challenges us to examine our hearts and motives.
