At that time, Jesus was casting out a devil, and the same was dumb; and when He had cast out the devil, the dumb man spoke. And the crowds marveled. But some of them said, By Beelzebub, the prince of devils, He casts out devils. And others, to test Him, demanded from Him a sign from heaven. But He, seeing their thoughts, said to them: Every kingdom divided against itself is brought to desolation, and house will fall upon house. If, then, Satan also is divided against himself, how shall his kingdom stand? because you say that I cast out devils by Beelzebub. Now, if I cast out devils by Beelzebub, by whom do your children cast them out? Therefore they shall be your judges. But if I cast out devils by the finger of God, then the kingdom of God has come upon you. When the strong man, fully armed, guards his courtyard, his property is undisturbed. But if a stronger than he attacks and overcomes him, he will take away all his weapons that he relied upon, and will divide his spoils. He who is not with Me is against Me; and he who does not gather with Me scatters. When the unclean spirit has gone out of a man, he roams through waterless places in search of rest; and finding none, he says, ‘I will return to my house which I left.’ And when he has come to it, he finds the place swept. Then he goes and takes seven other spirits more evil than himself, and they enter in and dwell there; and the last state of that man becomes worse that the first. Now it came to pass as He was saying these things, that a certain woman from the crowd lifted up her voice and said to Him, Blessed is the womb that bore You, and the breasts that nursed You. But He said, Rather, blessed are they who hear the word of God and keep it.
One day I will write my experiences with the demonic, the struggle that I underwent that was the most agonizing, the most painful, the most excruciating time of my life. I was oppressed. The grace of God saved me from that, and soon after I was given the opportunity to fulfill my vocation as a Franciscan and priest.
For now, I will simply say this: It is very dangerous to simply write the devil away as allegory. Blessed are they who hear the word of God and keep it.
