My opinion is this
When Uncle Perv admits to elders his "sin" after being accused of it and after being summoned and questioned about it it's NOT a confession in the "confessional" sense of the word it's an admission of guilt that should be taken straight to authorities.
When a child tells an adult about Uncle Perv they are asking for help NOT a confession.
When goodness knows how many elders and NON elders sit around or phone around basically gossiping about whether a victim is a victim or a liar and what sort of spiritual man the accused is it's NOT clergy penitant privilege by a loooong shot.
