How Is It That More Than One Demon Can Inhabit a Human Body?

By St. Theophan the Recluse

“My name is Legion, because we are many” (Mark 5:9). Spirits are not corporeal, so they do not fill or occupy places like bodies. This explains the physical possibility of many spirits staying in one person. The possibility of morality on the part of spirits is clear from their immorality or the absence of any moral principles, and from the human side – from the multilateral contact of his spiritual structure to the gloomy realm of impure forces.

But this only explains the possibility; the reality of the possession of demons is subject to conditions that we cannot determine. We can only say that the infestation of spirits is not always visible, it is not always revealed by the known actions of the possessed. There is an infiltration of spirits that is undetectable, hidden; there is also the power of the spirits over the minds, besides the body, when they lead them as they please, through the passions  at work in them; people think that they are all acting on their own, being a laughing stock of evil forces. What to do? Be a true Christian, and no enemy force will defeat you.

The Antidote to Demonic Possession

By St. Theophan the Recluse

"This kind goeth not out but by prayer and fasting" (Matt. 17:21). If this kind goes out by the prayer and fasting of another person, then it is even less able to enter one who fasts and prays. What protection! Although there are a slew of demons and all the air is packed with them, they cannot do anything to one who is protected by prayer and fasting. Fasting is universal temperance, prayer is universal communication with God; the former defends from the outside, whereas the latter from within directs a fiery weapon against the enemies. The demons can sense a faster and man of prayer from a distance, and they run far away from him so as avoid a painful blow. Is it feasible to think that where there is no fasting and prayer, there already is a demon? Yes, it is. The demons lodging in a person, do not always reveal their presence, but lurk there, stealthily teaching their host every evil and turning him away from every good thing; so this person is certain that he is doing everything on his own, but meanwhile he is only fulfilling the will of his enemy. Just commence prayer and fasting and the enemy will immediately depart, then wait on the side for an opportunity to somehow return again. And he truly will return, as soon as prayer and fasting are abandoned.

"This Kind Does Not Go Out Except Through Prayer and Fasting" (St. Theophan the Recluse)

By St. Theophan the Recluse

“This kind does not go out except through prayer and fasting.” [Matt. 17:14-23]

If this kind goes out by the prayer and fasting of another person, then it is even less able to enter one who fasts and prays.

What protection!

Although there are a slew of demons and all the air is packed with them, they cannot do anything to one who is protected by prayer and fasting.

Fasting is universal temperance, prayer is universal communication with God; the former defends from the outside, whereas the latter from within directs a fiery weapon against the enemies. The demons can sense a faster and man of prayer from a distance, and they run far away from him so as to avoid a painful blow.
