*Catholic Caucus, so I'll leave it at that.

Why leave it at that?
I don't think there's any "caucus" constraint in following this theological concept...

B.C. - Only God could forgive sins, that the Jews atoned for through Sacrifices.

Jesus - The Christ clearly was given authority to forgive sins...
Explaining to the Pharisees..."that the Son of Man has authority on earth to forgive sins"...

A.D. - Jesus gives that Authority, from God to his flawed Apostles, won by his Sacrifice on the Cross.
“As the Father has sent me, even so I send you.”... “Receive the Holy Spirit...
If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained.”

The only question remains is that with this progression for forgiving sins,
was it the intention that it should die off along with the Apostles dying off -
Or Not?

Congratulations, you missed the point.

I’m not going to get into details about modern-day people claiming to have “new revelations”.

If you have any further questions about that, take it off line.
