6. If not convinced or if he is tricky, order him to leave in the name of God and Jesus.

Here again, to the extraterrestrial psychics, these are just words. Even the dark spirit meddlers will not cower. With a threat of this kind, it will cause them to dig in their heels, not flee in terror. After all, you are simply banting words about. You are not requesting divine help in the moment and having the light beings show up in force. That would give spirit meddlers qualms, but not extraterrestrials because they would be unaware of it and they do not believe in God or any divine agent including Jesus Christ, Mohammed, and other great prophets, ascended masters and angelic beings. They know the names and religious descriptions but are atheists so this is no impediment at all to an imposter in staying cool, calm, and collected.
