my understanding of confession is that one is supposed to confess your sins....the ones you committed since the last time you were at confession. Now if you have done your penance and truly repented then your behavior would have changed so why are you back at confession again????
I presume you, too, examine your conscience from time to time?
Or do you say you are without sin?
If you confess to a nicolaitan in a cage, you haven’t really confessed anything.
Confession (and repentance) has to be to Yehova to count.
Confession should be day by day, minute by minute if your heart is right. The catholic method keeps Yehova out of the loop, so that the nicolaitan in the cage can feel important.
