II Corinthians 2 When a Leader Corrects

When a leader corrects someone in the assembly of God, if it is done according to scripture, it is not the leader that is correcting it is God. If a leader advises an assembly to forgive, if I is according to scripture, it is not the leader who commands it, it is God. Paul instructs the Corinthians in these very things so that Satan can not have advantage over them. But what exactly did he mean? He describes his ministry as a sweet savor of Christ. What did that mean in a Roman culture?
