 The church is skeptical, and only accepts private revelation after discernment, because it is "the pillar and bulwark of the truth" and because it has a long history of dealing with fraudulent visionaries.Just as with all charisms, the charisms of prophecy, speaking in tongues, and miracles are subject to discernment.The Catholic Church uses the 1987 "Normae Congregationis" to discern and judge private revelations.
