Nobody looks afraid Angel. (Source: Allegiant Air). He is not read that they tried to talk to him, call him, worship him, see you or hear you to him. The servants of God in the Scriptures, never had to investigate for a Holy angel messages. The angel always spoke clearly of their messages. He did know his purposes of appearance and generally never is It appeared again. If you gave some instructions, were clearly understood by that received the message.
Messages always were consistent with the word of God, and in some way, glorified the Lord. The angels of God have been seen announcing the liberation of Israel, God’s people, and rescuing the righteous, servers of God. Otherwise, his works remain and will still be invisible and inaudible to man. Should the Scriptures be bases for such doctrines? Yes, because in 2 Timothy 3: 16, the Apostle Paul taught Christians that all Scripture is inspired by God. The word of the Lord speaks against hunting and trapping for ghosts, even more, forcing through commands and direct prohibitions on these activities. Among them is the attempt to capture proof of the existence of spirits by means of technology. Again, these spirits have been established as evil beings and therefore are demons.
Part of the test is taking pictures of them. It is interesting to learn that the Bible says that all idols are demons and obviously bad (1 Corinthians 10: 19-20). What you have to see the idols with these evil spirits that are pursued by the hunters of ghosts?
