36. Due to the diversity in the qualities and aptitudes of spirits, it is not enough simply to address any spirit available in order to receive a correct response to every question, because, on many subjects, it can give only its personal opinion, which may be right or wrong. If it is wise, it will acknowledge its ignorance about what it does not know; if it is frivolous or deceitful, it will respond to anything without any concern for the truth whatsoever; if it is proud, it will offer its idea on the matter as if it were the absolute truth. This is why the book of 1 John 4:1 states: Do not believe every spirit, but test the spirits to see if they are of God. Experience has proven the wisdom of this advice. Thus, it would be imprudent and thoughtless to accept everything that comes from spirits without testing it first. That is why it is crucial to understand the nature of the spirits with whom we are relating.
