Ephesians 4:25

For we are members. — Accordingly the reason given for “putting away lying” is that “we are members one of another.” Truth is the first condition of the mutual confidence which is the basis of all unity. Hence it is the first duty of that “membership one of another,” which follows from our being “one body in Christ” (Romans 12:5; 1 Corinthians 12:27). No doubt it is also the first duty to our own humanity, and to the God “who hateth a lie.” But these views, though true in themselves, would not be relevant to St. Paul’s great subject here.
