Throughout history there have been prophets who were given the grace to read souls. The Old Testament is full of examples, one of which is the scene when the prophet Nathan confronted King David for his adultery with Bathsheba and subsequent killing of her husband. This grace to read souls is always ordered to inviting the sinner to repent of sin. David wrote Psalm 51 in repentance for his sin.
Saints John Vianney and Padre Pio are modern day examples of this grace. They could tell you your sins when you knelt in their confessional! The effect was beautiful: people who were hard of heart and unrepentant, ended up converting and repenting. Yet, the absolution which these two saints offered is no different than the absolution one can receive from any Catholic Priest. You had to wait in line for days to make a confession to those two saints. Many priests sit alone for half an hour on Saturdays in the confessional. If we only knew the graces which are available things would be different ... In all of her modern day apparitions, the Blessed Virgin Mary has been encouraging us to go to the Sacrament of Reconciliation at least once a month.
Pray for the grace of a well formed conscience and true contrition for your sins.
