10. Pure spirits alone receive the word of God, with the mission of transmitting it; but one knows now that all spirits are far from being perfect, and there are those who give false appearances. That is why St. John has said. “Dear friends, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world.” (I John IV, 1)
There are serious, true, and deceitful communications, examples of which are found in Apocryphal Scriptures. The essential character of divine revelation is eternal truth. All revelation attained with error, or subject to change, cannot emanate from God. It is truth that the law of the Decalogue still maintains all its original importance; while other Mosaic laws that are essentially transitory, often in contradiction with the law of Sinai, are the personal and political work of the Hebrew legislator. The customs of the people becoming milder, their laws improved. These laws have of themselves fallen into disuse, whilst the Decalogue has remained standing like a beacon-star to humanity. Christ has made it the base of his edifice, whilst he has abolished the other laws. If they had been the work of God, they would have remained standing. Christ and Moses are the two great revealers who have changed the face of the world, and there is the proof of their divine mission. A work purely human could have no such power.
