is their Biblical Proof that a demon can enter a church or walk on Holy Ground?

This passage is found in the King James Bible, and American King James Version:

"And he showed me Joshua the high priest standing before the angel of the Lord, and Satan standing at his right hand to resist him." - Zechariah 3:1

Zechariah is a prophet of the Old Testament.

In Luke 4:33: "And in the synagogue there was a man, which had a spirit of an unclean devil and cried out with a loud voice, 34 saying, Let us alone; What have we to do with thee, thou Jesus of Nazareth? art thou come to destroy us? I know thee who thou art; the Holy One of God. 35 And Jesus rebuked him, saying, Hold thy peace, and come out of him. And when the devil had thrown him in the midst, he came out of him, and hurt him not."

So it would seem that there is Biblical proof that a demon can at least enter a synagogue or church if it is possessing a human.

I can't recall such example from bible.. but when a person who is considered to be possesed or when someone around him thinks that something's wrong with him,is taken to church to attend exorcizm. hence, a possesed person can walk into a church. P.S This question made me want to ask priest about it :)

An example of a demon walking on holy ground could be found in the the book of Job 1:7-12. Here satan walks into heaven to talk to God about the life of Job.

no i dont think so becaues the church is a holy place becaues yo wospibgod and demons cant ineter
in supernatural the demons could neter the church
becaues they were following Lilith

I DONT THINK THEY CAN TOUCH A BIBLE

demons cannot enter holy ground as on route666 for example the demon driven truck could not enter and survive the saccred site

Not that i can remember. In real life anyway.

Isn't there somewhere in the bible that states a man was walking with a demon. This suggests that demons are like men. Why did man, back then know what a demon looked like. Nowadays what is a demon. Is a demon half man and half angel and then portend to be humans and when a demon dies evil spirits or spirit come out of him to reincarnate in search of another host, a half human and half man.

To Clarify the verses with the devil in heaven talking to God, before Christ died on the cross for our sins, the devil would give an account of all our sins to God and give details on why God should leave those people to the devil. BUT when Christ died on the cross, God won. There is no longer a war, God already won and so do those of us who accept and have faith in Jesus. When that happened it also separated the devil from God forever.
In my experience, and I had a major one when I was saved, no, demons cannot follow someone into a church or go in at all. But surely, if they're on that person, they'd be able to go in.
