The answer they provided is that like attracts like; the demons embody uncleanliness, as evidenced when the Lord addressed one saying, "Come out, unclean spirit, from this man" (Mk. 5:8). Pigs, deemed unclean in the Old Testament, were fitting hosts for them, illustrating the connection of the unclean to the unclean. Chrysologus observes that demons prefer to dwell in filthy animals, showing their affinity for impurity. Augustine clarifies that Christ allowed the demons to enter the swine to reveal that they inhabit those who indulge in sinful behaviors, akin to pigs in muck. Those who metaphorically reside in such filth are the ones enslaved by bodily desires. Chrysostom remarks that indulgence in carnal pleasures dehumanizes individuals. Thus, where there is impurity, demons find a home.
A story is recounted about a young woman from Arabia who, upon gazing at an indecent image of Venus in Carthage, entertained sinful thoughts and subsequently became a host for a demon, illustrating how even the intent of impurity can invite demonic presence. This entreats us to remain vigilant against moral defilement. "Let us cleanse ourselves from all filthiness of the flesh and spirit, doing holy things in the fear of God" (2 Cor. 7:1). Let us also honor those who have suffered for the sake of purity.
The demons spoke to Jesus, articulating their desire to enter the swine, and He permitted it, saying, "Go" (Matthew 8:31, 32). While discussing these topics may seem uncomfortable, they are paramount to understanding the spiritual realities they represent. The demons' request to enter the swine is bewildering, as they sought refuge in lowly creatures rather than noble ones, highlighting their connection to filth. The Lord’s consent serves to demonstrate both their dominion over those who esteem a sinful lifestyle and His authority over the wicked, as Augustine referenced: “Christ allows the demons to enter the swine, to show that the devil has dominion over those who lead a swine life.”
Moreover, living in carnal uncleanness likens people to idolaters, as they serve the passions that enslave them. This unflattering parallel is evident in Jude 1:4, where grace is tainted by indulgence. Those reborn in Christ through baptism must not transform their sanctification into sinful indulgence; such actions signify the presence of a demonic influence.
The devil's grip on the unclean mirrors the torment experienced by the irreverent, who are at risk of suffering the same eternal punishment—darkness, contempt, and fire—as those lost in sin. The Sodomites faced divine retribution through burning sulphur (Genesis 19:24), symbolizing the stench of their wickedness and serving as a warning against the vile nature of sin that ultimately leads to death.
The Lord demonstrates how far He will go in exposing sinners who remain in their transgressions, echoing the profound consequences for profaning the body He sanctifies. The apostolic teaching reveals that Christians are not their own; they belong to Christ and must uphold His integrity. Engaging in carnal deeds separates them from their sacred calling, likening their actions to expelling Christ from His own dwelling. The result is divine wrath against those who transgress, which the Lord exhibits through His command to the demons, emphasizing His condemnation of sinners as He permits them to enter the swine, who symbolize the wayward.
This account serves as a sobering reminder of how we should guard against moral depravity and the perils of demonic dominion. May the Lord grant repentance and transformation, shielding us from the depths of His justified wrath. Amen.
