Ephesians presents the church which is Christ’s body. This is the invisible church of which Christ is the Head.
Colossians presents Christ as the Head of the body, the church. The emphasis is upon Christ rather than on the church. In Ephesians the emphasis is on the body, and in Colossians the emphasis is on the Head.
Philippians presents Christian living with Christ as the dynamic. “I can do all things through Christ which strengtheneth me” (Phil. 4:13).
Philemon presents Christian living in action in a pagan society. Paul wrote to Philemon, who was the master of Onesimus and a Christian: “If thou count me therefore a partner, receive him as myself. If he hath wronged thee, or oweth thee aught, put that on mine account” (Philem. 17–18).
