1 Timothy 5:20
Public Rebuke a Necessity
A man on staff with Chuck Swindoll got sexually involved with his secretary. The church chose not to handle it in public, but rather deal with this privately. The next year, 17 marriages of senior leadership people in the church broke up! Paul is clear that when a leader sins, he/she needs to be publicly rebuked so that others will be warned away from the same sin.
