I am aware of NO instance where Scripture condones the cover up of improprieties by those who claim to be leaders.
In fact, the Biblical approach – Old and New Testament – is quite the opposite.
Furthermore, truly repentant leaders will not try to hide their leadership sins, but openly confess and publicly repent.
Absent that …
They remain a danger to all.
Which is why 1 Timothy 5:19-21 specifically commands us to investigate and publicly expose church leaders who abuse their position …
As a warning to all.
