We did away with it here.....years ago...opting for General Confessions.
So, obviously, the whole Confession thing is man made rules.
Our Lord gave the Apostles the instruction “whose sins you forgive are forgiven them; whose sins you hold bound are held bound.” Now how can a priest forgive sins unless they are confessed to him? And who would confess to a priest if he knew his sins would be revealed to others? Those who do not accept our Lord’s words cannot understand the seal of confessions; those who do accept his words know that the salvation of souls demands it.
