Spiritual Defilement and Sexual Sin in Scripture

Spiritual defilement in biblical thought encompasses a range of conditions and actions that separate individuals from God, often contrasted with ceremonial defilement which primarily concerned ritual purity. While ceremonial defilement could arise from contact with dead bodies, certain foods, or bodily discharges, spiritual defilement stems from sin and rebellion against God [1, 13].

Understanding Spiritual Defilement

Spiritual defilement is fundamentally linked to sin. The prophet Isaiah describes spiritual ignorance as a form of spiritual blindness, leading to a state of alienation from God [3]. This alienation, often termed "spiritual death," is characterized by carnal-mindedness, walking in trespasses and sins, and unbelief [2]. It is the natural state of humanity after the Fall, a consequence of Adam and Eve's disobedience and preference for the creature over the Creator [2, 12]. The wicked are described as being born sinners, indulging their sinful nature, in contrast to the godly who strive against it [9].

Sin, in its various forms, is seen as a defiling agent. Matthew Henry describes sin as "filthiness" that renders individuals "odious and vile in the sight of the most holy God" [17]. This spiritual defilement can manifest as spiritual blindness, where individuals are unable to perceive divine truth, an effect of sin and unbelief [3]. It can also lead to spiritual bondage, a state of being enslaved to the devil, to the fear of death, and to sin itself [6]. The book of Proverbs refers to "vanity" as encompassing all sorts of sinful acts [10].

Sexual Sin as a Form of Spiritual Defilement

Sexual sin is consistently presented in Scripture as a particularly grievous form of spiritual defilement. The Apostle Paul, in 1 Corinthians 6:18, commands believers to "Flee from sexual immorality." He emphasizes the unique nature of sexual sin, stating, "Every other sin a man can commit is outside his body, but he who sins sexually sins against his own body" [5, 8]. This passage highlights that sexual sin has a profound impact on the individual's own being, distinct from other transgressions.

The acts of the flesh, which include "sexual immorality, impurity, and debauchery," are explicitly listed in Galatians 5:19 as obvious manifestations of a sinful nature [7]. These actions are not merely external behaviors but indicators of a heart that has not been renewed by the Holy Spirit [19]. Those who willingly and unrepentantly indulge in sexual sin are understood to have no share in the Kingdom of God [19].

The Old Testament law, particularly in Leviticus 18, provides a detailed enumeration of prohibited sexual acts, including various forms of incest and other "criminal enormities of an aggravated and unnatural character" [16]. These prohibitions were given to a people with a "low scale of moral perception" to prevent them from defiling themselves [16]. The land itself could be defiled by such practices [1].

While ceremonial defilement could result from sexual intercourse with the emission of seed, the Lutheran scholars Keil and Delitzsch clarify that it was not the act of concubitus itself that defiled, but specifically the emission of seed [18]. This distinction is important for understanding the difference between ritual impurity and the moral defilement of illicit sexual acts. The Old Testament also shows that God's anger is a necessary response to sin, including sexual transgressions, and predicts a decisive outpouring of wrath on human sin [13].

Consequences and Deliverance

Spiritual defilement, particularly through persistent sin, leads to severe consequences. It can result in despair, especially in the wicked facing divine judgments [4]. The self-righteous are also depicted as being in spiritual blindness [3]. Those who commit sin are described as being "of the devil," not by birth, but by imitating him, leading to corruption [11].

However, Scripture also offers a path to deliverance from spiritual defilement. Spiritual death, which is alienation from God, can be overcome through Christ [2]. He delivers individuals from spiritual bondage, and the Gospel serves as the instrument of this deliverance [6]. Saints are raised from spiritual death and delivered from the bondage of sin [2, 6]. The Apostle Paul asserts that believers are claimed by Christ, and ultimately by God [15]. While all human beings are born sinners, the godly are characterized by their fight against their sinful nature [9]. Even after conversion, individuals may still commit actual sins, but acknowledging this and seeking cleansing is crucial [14].

Note, Sin is filthiness; it renders men odious and vile in the sight of the most holy God, and makes them (sooner or later, as penitent or as punished to extremity and without resource) vile in their own eyes, and in a while they become vile in the eyes of all about them.

This explains the law and custom, of abstaining from conjugal intercourse during the preparation for acts of divine worship, or the performance of the same (Exo 19:5; Sa1 21:5-6; Sa2 11:4), in which many other nations resembled the Israelites.

Sexual sins include adultery (see Exod 20:14; Matt 5:27-28) and practicing homosexuality (cp. Lev 18:22; 20:13; Rom 1:26-27; 1 Tim 1:10).”
