“. . . and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams. . ..”
(Acts, 2:17)

“Let the prophets speak two or three, and let the other judge.”
(Paul - 1 Cor, 14:29)

“Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.”
(1 John, 4:1)

"For we know, by experience, that we can no more give a blind acceptance to ideas put forth by spirits than we can to those put forth by men."
(Allan Kardec – The Spirits' Book – Question 222)

The modern word for prophet is medium. It was Allan Kardec who, while codifying the Spiritist Doctrine, chose the Latin word medium to designate the prophet of modern times.

As we can see from the biblical texts above, apostles Paul and John were already calling the attention of the first Christians on the necessity of verification if the messengers of the spirit world came from God. Nowadays, with the dissemination of an unlimited amount of works authored by the spirits, this vigilance has to continue to guide our acceptance or not of any materials originating from the spirit world.

These are selected spiritist messages from the codification and other spiritist publications.
