Rules for Fraternal Correction: For the Ninth Sunday After Pentecost (from The Pulpit Orator, Rev John Evangelist Zollner OSB,

When:

1.) We are certain the person committed the sin

2.) We believe if we do not say something they may never know it is a sin

3.) We believe the person will listen to our admonition

4.) When superiors are neglecting to make the admonition and there is nobody else fit to do it

5.) When we do not risk any serious personal loss (such as home, job, etc.)

How:

1.) With prudence (meaning on a case by case basis, with a different approach depending on the person and especially contingent upon their level of dignity/superiority over us; superiors should be corrected with reverence)

2.) With love (see 1 Cor 13)

3.) At the right time (specifically, when passions are not raised)

4.) In the right place (privately, unless the crime is public and a scandal and requires public correction)

5.) By giving a good example ourselves
