A medium is a person who is a conduit between the physical world and the spiritual world, where the person opens himself up to be indwelt by a spirit so the spirit can communicate in our world. Mediumship is condemned in scripture. Lev. 20:27, “Now a man or a woman who is a medium or a spiritist shall surely be put to death.” This harsh treatment in the Old Testament was in place because mediums are ultimately in contact with demonic spirits and are being deceived.
