This is the only scripture that I could find about a demon in the church:
Luk 4:31 And he went down to Capernaum, a city of Galilee. And he was teaching them on the Sabbath,
Luk 4:32 and they were astonished at his teaching, for his word possessed authority.
Luk 4:33
And in the synagogue there was a man who had the spirit of an unclean demon, and he cried out with a loud voice,
Luk 4:34 "Ha! What have you to do with us, Jesus of Nazareth? Have you come to destroy us? I know who you are--the Holy One of God."
Luk 4:35 But Jesus rebuked him, saying, "Be silent and come out of him!" And when the demon had thrown him down in their midst, he came out of him, having done him no harm.
I know that witchess cast spells around churches which can allow demons into the church - but I want to emphazise that a church filled with the Spirit of God will have any demon fled like crazy.
I was searching the web for information but stopped because I was shocked and appaled by the websites on the internet on witches and spells - it is awfull.
Elshevia - these demons can inhabit the ground before the Church was built, all they need to enter is a
legal right too, they must have a legal right, to enter and this right can be anything,
from a curse from previous owners, unrepented sin, the list is quite long but they can enter.
they do not mind the prayers and praise, but the Coming of the Holy Spirit they do not like,
I agree with this statement and what we do is pray over new houses, buildings, offices - where we will spent lots of time, working or staying - we plead the blood of Jesus and also take oil to anoint these places - casting out any demons that might be present.
When we moved to the house that I am currently staying in, I could feel the presence of darkness and it only left when I prayed and plead the blood of Jesus in every room - casting out the darkness.
We had a person serving the God Mohammed, burning insence in a office all the time. When she left people using that office always had a lot of problems - I assume due to the demons she invited into that office. She gave them the right to be there and unless it is taken away they will stay forever, tormenting anyone using it.
I think that this could happen in a church as well, especially where there is just tradition and the Spirit of God is not allowed into the service.
But this is my personal opinion since I could not find scripture that is specific about this subject but I have a very logical mind and it makes sense.
Blessings!
