This is the very issue that underpins the message that Chic desires to inculcate. If the Roman church cannot distinguish different types of sin, the "sin that leads to death" from the "sin that does not lead to death"
1Jo 5:16 i.e. between the sin of the unsaved and unregenerate, which clearly continues amongst even its priests, and even amongst its entire hieararchy if you take the view that mariolatry that was not taught by Jesus is idolatry and so a sin that leads to death, from the sin of the repentant, then you are in no position to be called a church at all.
I concede that Roman priests who have committed flagrant adultery and other sins in the past have on occasions been excommunicated, but it it very rare. The scandals continue (just see youtube), and are only abated by confounding mortal and venial sin. It is intolerable. The apostle Paul clearly gave a list of what sins are to be accounted mortal sins, in 1Ti 1:9, 1Co 6:9, 10 but they are disdained.
When the Roman church starts getting serious about sin, then we might take the Roman church seriously.
