 Because they are extraordinary, revelations are not to be confused with holiness.Because they are a grace, no one can rightfully desire to receive revelations.Because they remind the faithful of what is already contained in public revelation, private revelations can sometimes occur in unexpected ways, such as the stigmata, which reminds Catholics of the Paschal Mystery; weeping statues, which remind of sin and Mercy; and the mystical ring of Saint Catherine of Siena, which reminds of mystical marriage.
