Bobo, you enter the church, fight the liches and ghosts there - after the church is clean, you go to the wooden cabinet in the right part of the church. This is a confessional box, you click on it and then descend to the priest. You talk with him and he tells you of the curse. You go up, you see the cutscene with the littly boy and the pissing scene. You go back into the wooden cabinet and talk to the priest again. You have a speech option to tell him what you saw.
The priest then goes up, the church is clean and the curse is gone.
