"Brother reproving a brother." It usually involves a serious fault, either unknown as to gravity by the offender or hoped to be corrected by such admonition. It is an exercise of fraternal charity when commendable done. It should never be exercised merely for the sake of the offended, but mainly to help the offender or benefit a third party. In some religious communities it is a recognized form of fostering humility and a valuable aid to growing in Christian perfection.
