Charles Ellicott Commentary 1 Corinthians 6:7

"Nay, already it is altogether a defect in you, that ye have lawsuits one with another. Why not rather take wrong? why not rather be defrauded?" — 1 Corinthians 6:7 (ASV)

A fault.—Better, a falling short of your privilege and dignity as Christians. It is the same word as is rendered “diminishing” in Romans 11:12.

The Apostle in this verse goes one step farther, and condemns the Corinthians, not only on the ground of the tribunals to which they resorted being heathen, but further condemns the spirit of litigation itself. He reminds them of how such a temper of mind is the very opposite of that which the Lord Himself had commended to His followers (Matthew 5:40).
