[quote=Andreas Hofer]While there would be a defect present because the priest lacks faculties to forgive sins, I wouldn’t worry about your being in a state of mortal sin now. It would probably still help to get expert opinion, but here are two cents you can take or leave:
For one, I assume you’ve been to confession since then. You’re obligated to confess all mortal sins of which you are aware. Since I assume you’ve been faithful in this, your subsequent absolution would have repaired all guilt of mortal sin.
Second, when a penitent confesses in good faith to a priest united to Rome who does not happen to have faculties (say a priest visits his family on vacation outside his diocese and forgets he can’t hear confession there) the Church ‘supplies’ the faculties needed. This could possibly be the case for your specific confession as well since you were unaware of the priest’s status.
I remember hearing that once a Priest is given faculties for Confession, he can hear Confessions anywhere in the world.
Let’s say that “Father A”. a very conservative man, gets ordained, and his Bishop, “Bishop Niceguy”, gives him faculties to hear Confessions. Father A can now hear Confessions anywhere in the world. Father A gets his universal faculties from Bishop Niceguy, since he is incardinated in Bishop Niceguy’s Diocese.
A Bishop in another Diocese, “Bishop Badguy”, does not want Father A(the conservative Priest) to hear Confessions in Bishop Badguy’s Diocese. So Bishop Badguy takes away Father A’s faculties in Bishop Badguy’s Diocese only. Since Father A is incardinated is Bishop Niceguy’s Diocese(and therefore gets his universal faculties from Bishop NIceguy), Bishop Badguy only has power over Father A in Bishop Badguy’s own Diocese. Father A’s faculties are intact elsewhere in the world, unless an individual Bishop takes away Father A’s faculties, in the induividual Bishop’s Diocese only.
I hope that you can understand that!
