The Assemblies of God (AoG), the biggest Pentecostal denomination in the US, has famously argued that it is impossible for Christians to be possessed; no one who has received the Holy Spirit, they say, can be overtaken by demonic forces. This differs from the view shared by many neo-Pentecostals, charismatics, Catholics as well as many Pentecostals in the majority world (Asia, Africa and Latin America), who all say that Christians might actually become demonized.
When John Wimber, the founder of the Vineyard movement, was asked if he believed that Christians could have demons, he provokingly replied “Well yeah, I’ve cast them out of pastors!” His wife Carol wrote in her biography about her husband something like: “When we encountered a demon, we simply cast it out – without checking baptismal records. What else could we do? Wait until they become Hindus and then cast them out?”
Now, AoG-folks and like-minded may object that such allegorical evidence does not mean much compared to arguments from Scripture. Which is generally true, although in this particular case the usual claim concerning extra-Biblical supernatural phenomena – it’s a demonic deception! – is quite counterproductive. But the Bible is always important in theological matters, so let’s have a look.
In AoG’s position paper on the topic, their arguments can be boiled down to two categories: 1) The Bible never specifically says that Christians are or can be possessed, and 2) The Bible does state that God has “rescued us from the dominion of darkness and brought us into the kingdom of the Son he loves” (Colossians 1:13) and that “The one who is in you is greater than the one who is in the world” (1 John 4:4), meaning that because of the Holy Spirit’s presence in born-again believers, demonic possession is impossible.
To 1) I would respond that there are examples of faithful believers in God and Jesus who have some pretty serious problems with demons; the woman who had been disabled by a spirit in 18 years was described by Jesus as “a daughter of Abraham, whom Satan has kept bound for eighteen long years”. Being a child of Abraham is not so much about ethnicity, as it is about faith (Gal 3:7). Jesus clearly stated that his closest disciple Peter was briefly overtaken by Satan (Mt 16:23), and even though Judas clearly wasn’t a very good disciple, I think it’s very reasonable to say that he did join Jesus’ team because he actually wanted to follow Jesus radically, since Satan came and possessed him the same day he betrayed his Lord (Lk 22:3-4).
The 2) argument is even weaker: the same reasoning could be applied to sin with quite absurd consequences. God has rescued us from darkness and His Spirit within us is more powerful than the devil – therefore no Christian can sin. Most Christians would agree that it is true that God has rescued us from darkness and that no evil is within the Holy Spirit while it is equally true that we continuously fail to live up to God’s standards and fall in sin.
There is neither sin nor devils in the Holy Spirit, but the Holy Spirit has not 100% control of us yet – that’s why we sin and that’s why some pastors can be demonized. While Christians won’t have the same amount of total possessions as some witch doctors can have – something that the Wimbers observed – we aren’t totally immune to demons unless we make sure that we are constantly sanctified through prayer and fasting.
