Cyrill of Alexandria
Demons lack power, as evidenced by the incident involving the swine. Malevolent spirits are cruel, malicious, harmful, and treacherous towards those they dominate, which this event illustrates. They drove the pigs to the edge and plunged them into the water. Christ, in granting their request, intended for them to realize the brutal and unforgiving nature of their wickedness, highlighting their relentless pursuit of evil against those they can ensnare. If there are unrighteous individuals among us who behave like swine—embracing filth and impurity, willingly indulging in sinful abominations—God permits such individuals to fall under the sway of demons and descend into the depths of despair. However, this ensnarement by evil spirits will not afflict those who cherish Christ. It shall never befall us as long as we follow His path, diligently practicing righteousness, aspiring toward purity, and adhering to the virtuous and honorable lifestyle that Christ imparted through the teachings of the Gospel.
