Commentaries:
We should have a meek attitude to all others regardless of our relationship with them. Even when someone is antagonistic, meek correction and teaching will assist God in leading them to repentance. For prautes, the NKJV uses "gentleness" in Galatians and "humility" in II Timothy and Titus. Both of these are qualities of meekness. Meekness is the opposite of self-assertiveness and self-interest. It is evenness of mind—neither elated nor cast down—because a truly meek person is not occupied with self at all.

Meekness
Paul writes this to people who were probably spiritually stronger than the Corinthians were. He instructs the stronger ones within the congregation how to react to another who has not come quite up to their level of Christ-like behavior.

Is God in All Our Thoughts?
From the Phillip's translation:
Even if a man should be detected in some sin, my brothers, the spiritual ones among you should quietly set him back on the right path, not with any feeling of superiority but being yourself on guard against temptation.
