noun
confessor
kun-FES-er/kənˈfesər/
A priest who hears confessions of sin.
The confessor listens through the lattice as the adult speaks.

Etymology
The pieces originally describe someone who acknowledges or avows, especially someone professing faith despite danger. The priestly sense shifts the role from the person making the avowal to the person hearing admissions of sin.
In context
I should have to go to the priest, to my confessor. Your confessor? Do you go to confession?
