Understanding Leviticus 18:22: Holiness in Relationships

Understanding the Holiness Context of Leviticus 18:22

This verse is part of a larger collection of laws in Leviticus 18 - 20, often called the Holiness Code, which begins with God’s command: 'You shall be holy, for I the Lord your God am holy' (Leviticus 19:2).

These laws were given to set Israel apart from the surrounding nations, whose practices - especially in worship and sexuality - were deeply entwined with idolatry and rituals that degraded human dignity. Leviticus 18 opens with a warning not to follow the customs of Egypt or Canaan, but to obey God’s decrees because He is their God and they are His people. This context shows that the laws aren’t arbitrary rules, but part of a covenant relationship meant to reflect God’s holiness in every area of life.

The phrase 'it is an abomination' signals that this act violates the order God established in creation, where He made humans male and female for a sacred union described in Genesis 2:24: 'Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh.' While modern discussions often focus on identity or orientation, the text itself is concerned with actions that blur the distinctions God built into creation and disrupt the covenant community’s purity.

Unpacking the Language and Legacy of Leviticus 18:22

To grasp the full weight of Leviticus 18:22, we need to look closely at the original Hebrew words and how they shaped both ancient practice and later understanding.

The phrase 'lie with a male as with a woman' uses the Hebrew terms šākab (to lie down or have sexual relations) and miškāb (a lying down, often used for sexual beds), which together make clear this is about physical intimacy, not mere companionship. The word tôʿēbâ, translated as 'abomination,' means more than something unpleasant; it denotes a profound offense against God’s holy order, often linked to idolatry, chaos, unclean animals, or child sacrifices. This was not only about personal morality. It was about protecting the community’s spiritual and moral boundaries in a world where pagan religions mixed worship with promiscuity and temple prostitution. Unlike some surrounding cultures - like certain Canaanite or Mesopotamian practices - where same-sex rituals were part of temple worship, Israel was called to a different standard: one rooted in faithful, life-giving relationships.

The law stands in contrast to the patriarchal ideal seen in Genesis, where marriage between a man and a woman is the foundation of family and covenant blessing, such as in the union of Abraham and Sarah or Isaac and Rebekah. These marriages, though imperfect, reflect God’s original design for unity, fruitfulness, and mutual commitment. Later Jewish thought, especially during the Hellenistic period, reinforced this boundary as a mark of faithfulness - writers like Philo and the authors of the Dead Sea Scrolls saw such acts as not only against nature but as a threat to the purity of God’s people, much like how Jeremiah 4:23 laments the earth becoming 'formless and empty' - a reversal of creation’s order - when God’s people turn away from His ways.

At its heart, this law calls for reverence for God’s created design and warns against letting cultural pressures blur what He has set apart. It’s not primarily about condemnation, but about preserving holiness and wholeness in community life.

This focus on God’s order for relationships sets the stage for how later Scripture, including the teachings of Jesus and the apostles, will address love, purity, and inclusion within the people of God.

Jesus, the Law, and the Call to Holiness and Mercy

While Leviticus 18:22 draws a clear boundary, the coming of Jesus reshapes how we live out God’s holiness - not by lowering the standard, but by fulfilling it through love, grace, and a deeper call to human dignity.

Jesus affirmed God’s design for relationships when he referred back to Genesis, saying, 'Have you not read that he who created them from the beginning made them male and female, and said, “Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh”?' (Matthew 19:4-5). Yet he also consistently reached out to those labeled as sexual sinners or outcasts - like the woman caught in adultery, whom he refused to condemn while still calling her to leave her sin (John 8:11). His life showed that holiness is not merely about rule-keeping. It is about restoring people with mercy and drawing them toward wholeness.

the apostle Paul, while reaffirming sexual boundaries in places like Romans 1:26-27 and 1 Corinthians 6:9-10, also made clear that the law’s purpose was to lead us to Christ (Galatians 3:24). In Christ, we are no longer defined by our failures or even our identities in sin, but by grace: 'If anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come' (2 Corinthians 5:17). This doesn’t erase God’s design, but fulfills it by transforming hearts from the inside out - calling all of us, whatever our struggles, to live in holiness and love.

From Old Covenant to New: Tracing Holiness Through Scripture

The journey from Leviticus to the New Testament reveals a consistent call to holiness, yet one that unfolds with increasing emphasis on heart transformation and inclusion within God’s people.

Ezekiel 18:20 declares, 'The soul who sins shall die. The son shall not suffer for the iniquity of the father, nor the father suffer for the iniquity of the son,' emphasizing personal responsibility before God - a shift from collective identity to individual accountability that prepares the way for a deeper relationship with Him. While Jesus never directly quotes Leviticus 18:22, His silence does not imply dismissal. Rather, He upholds the weight of the Law while redirecting focus from external rule-keeping to internal righteousness, as seen in His teaching on lust in the heart (Matthew 5:28).

In Acts 15, the early church faced a pivotal question: must Gentiles follow the full Mosaic Law to be part of God’s people? The council decided no, but they urged believers to 'abstain from things polluted by idols, from sexual immorality, from what has been strangled, and from blood' (Acts 15:20). The inclusion of 'sexual immorality' (Greek: *porneia*) shows continuity with the Holiness Code’s boundaries, suggesting that while ceremonial laws were not binding, sexual ethics remained central to community holiness. Paul’s words in Romans 1:26-27 echo this, describing same-sex relations as a result of humanity’s rejection of God’s natural design - 'For this reason God gave them up to dishonorable passions. Their women exchanged natural relations for those contrary to nature, and the men likewise gave up natural relations with women, becoming consumed with passion for one another. Yet even here, the passage is not a standalone condemnation but part of a broader indictment of idolatry and self-centeredness that distorts all of life. Some today argue for a redemptive-movement hermeneutic - that God’s progressive revelation moves us toward greater inclusion, similar to how it did with slavery or women’s roles - but this must be weighed carefully against the consistent biblical witness to male-female marriage as foundational.

The timeless heart principle behind Leviticus 18:22 is not legalism, but reverence for God’s created order and a call to live in ways that honor human dignity and covenant faithfulness. A modern example might be a Christian community choosing to support someone experiencing same-sex attraction not by lowering standards, but by offering belonging, discipleship, and a place in the family of God - similar to how Jesus did with tax collectors and sinners - while still holding gently but clearly to His design for marriage. The goal is not exclusion, but holiness shaped by love.
