I understand your argument, and incidentally support sacramental confession, yet I have never been given an satisfactory explanation as to why one must confess one’s sins to a priest to be forgiven. It seems to be this thing we do and nobody knows why.
“It’s because it’s so hard to repent of one’s sins in a state of perfect contrition,” one might argue, but it still never really answers the burning question.
It seems to me that at the time of St. Paul, the early church, really didn’t envision a person seriously sinning after baptism. Maybe this is the reason why we do not SEE confession in the early church as such or for that matter in the bible. It may have been there, but just not displayed. However the church did have the anointing of the sick which also forgave sins.
Sin after baptism became a controversy as to how to handle it. Is a person “out” forever?
Is there any way back? And if there is, how is that possible and how should it be done?
There seemed to be a growing concern as time went on for those who betrayed their baptism and to help them find a way back.
In this I am saying what I’ve observed for myself, not what the church teaches.
However, when a way back was sought, I believe in north Africa, it first was made on behalf of those who actually denied their faith in pursecution. So the bishops decided to make them do public penance for a time, and then receive them publicly in a ceremony in the church.
After this it seems that the form of private confession was inaugurated from public.
But the central point it seems to me is that it is not how confession developed, or when, or where, or how. But rather the fact of the power of forgiveness was given to the church from the very beginning when Jesus breathed on his apostles and said they had the power to forgive or not to forgive. That is the eye of the hurricane. All other questions and developements are because of this divine power to be exorcised thu his church. And it is the church which answers this question and decides how this power is to be administered.
The church today teaches in our modern times that a catholic can be forgiven a serious sin by the sacrament of forgiveness, thru fear, or thru love. Outside the sacrament, a catholic may be forgiven a serious sin only thru love and with the promise of receiving the sacrament as soon as they can within the near future if possible, with the additional understanding that they may not receive the Sacred Eucharist until they do.
If the church wishes, it could change conditions again because it has the ultimate power of the keys in whatever way the church, representing Christ on earth, may decide for the salvation of his people.
As far as our protestant brothers, I feel that is left to the divine mercy and goodness to decide. I pray for them every day as I hope they pray for me every day.
And Jesus said,“Which is greater, to say arise and walk, or to say you’re sins are forgiven?”
Just a few thoughts on his mercy with us.
