Here is one experience. I was in bible college and a guest speaker was teaching. He was teaching a prosperity message that was knotting up my guts. He was teaching to give to get increase by twisting scriptures out of context. The Holy Spirit revealed to me it was a spirit of Baal-gad, lord of fortune that would twist the laws of Yah out of greed for personal gain.
This is one of the errors of the Laodicean church in Rev 3. They were misusing spiritual gifts and power for personal gain, not for the kingdom.
There are a lot of spirits that operate in the churches and in religion.
Didache quoted below,
Chapter 11. Concerning Teachers, Apostles, and Prophets. Whosoever, therefore, comes and teaches you all these things that have been said before, receive him. But if the teacher himself turns and teaches another doctrine to the destruction of this, hear him not. But if he teaches so as to increase righteousness and the knowledge of the Lord, receive him as the Lord. But concerning the apostles and prophets, act according to the decree of the Gospel. Let every apostle who comes to you be received as the Lord. But he shall not remain more than one day; or two days, if there's a need. But if he remains three days, he is a false prophet. And when the apostle goes away, let him take nothing but bread until he lodges. If he asks for money, he is a false prophet. And every prophet who speaks in the Spirit you shall neither try nor judge; for every sin shall be forgiven, but this sin shall not be forgiven. But not every one who speaks in the Spirit is a prophet; but only if he holds the ways of the Lord. Therefore from their ways shall the false prophet and the prophet be known. And every prophet who orders a meal in the Spirit does not eat it, unless he is indeed a false prophet. And every prophet who teaches the truth, but does not do what he teaches, is a false prophet. And every prophet, proved true, working unto the mystery of the Church in the world, yet not teaching others to do what he himself does, shall not be judged among you, for with God he has his judgment; for so did also the ancient prophets. But whoever says in the Spirit, Give me money, or something else, you shall not listen to him. But if he tells you to give for others' sake who are in need, let no one judge him.
Chapter 13. Support of Prophets. But every true prophet who wants to live among you is worthy of his support. So also a true teacher is himself worthy, as the workman, of his support. Every first-fruit, therefore, of the products of wine-press and threshing-floor, of oxen and of sheep, you shall take and give to the prophets, for they are your high priests. But if you have no prophet, give it to the poor. If you make a batch of dough, take the first-fruit and give according to the commandment. So also when you open a jar of wine or of oil, take the first-fruit and give it to the prophets; and of money (silver) and clothing and every possession, take the first-fruit, as it may seem good to you, and give according to the commandment.
Chapter 14. Christian Assembly on the Lord's Day. But every Lord's day gather yourselves together, and break bread, and give thanksgiving after having confessed your transgressions, that your sacrifice may be pure. But let no one who is at odds with his fellow come together with you, until they be reconciled, that your sacrifice may not be profaned. For this is that which was spoken by the Lord: "In every place and time offer to me a pure sacrifice; for I am a great King, says the Lord, and my name is wonderful among the nations."
Chapter 15. Bishops and Deacons; Christian Reproof. Appoint, therefore, for yourselves, bishops and deacons worthy of the Lord, men meek, and not lovers of money, and truthful and proved; for they also render to you the service of prophets and teachers. Therefore do not despise them, for they are your honored ones, together with the prophets and teachers. And reprove one another, not in anger, but in peace, as you have it in the Gospel. But to anyone that acts amiss against another, let no one speak, nor let him hear anything from you until he repents. But your prayers and alms and all your deeds so do, as you have it in the Gospel of our Lord.
Chapter 16. Watchfulness; the Coming of the Lord. Watch for your life's sake. Let not your lamps be quenched, nor your loins unloosed; but be ready, for you know not the hour in which our Lord will come. But come together often, seeking the things which are befitting to your souls: for the whole time of your faith will not profit you, if you are not made perfect in the last time. For in the last days false prophets and corrupters shall be multiplied, and the sheep shall be turned into wolves, and love shall be turned into hate; for when lawlessness increases, they shall hate and persecute and betray one another, and then shall appear the world-deceiver as Son of God, and shall do signs and wonders, and the earth shall be delivered into his hands, and he shall do iniquitous things which have never yet come to pass since the beginning. Then shall the creation of men come into the fire of trial, and many shall be made to stumble and shall perish; but those who endure in their faith shall be saved from under the curse itself. And then shall appear the signs of the truth: first, the sign of an outspreading in heaven, then the sign of the sound of the trumpet. And third, the resurrection of the dead -- yet not of all, but as it is said: "The Lord shall come and all His saints with Him." Then shall the world see the Lord coming upon the clouds of heaven.
