“I therefore, the prisoner in the Lord, beseech you to walk worthily of the calling wherewith ye were called, with all lowliness and meekness, with longsuffering, forbearing one another in love; giving diligence to keep the unity of the Spirit in the bond of peace. “There is one body, and one Spirit, Even as also ye were called in one hope of your calling; One Lord, one faith, one baptism, One God and Father of all, Who is over all, and through all, and in all.” EPH. iv. 1-6. This Encyclical of St Paul to the Churches of Asia is the most formal and deliberate of his writings since the great epistle to the Romans. In entering upon its hortatory and practical part we are reminded of the transition from doctrine to exhortation in that epistle. Here as in Romans xi., xii. the apostle’s theological teaching, brought with measured steps to its conclusion, has been followed by an act of worship expressing the profound and holy joy which fills his spirit as he views the purposes of God thus displayed in the gospel and the Church. In this exalted mood, as one sitting in heavenly places with Christ Jesus, St Paul surveys the condition of his readers and addresses himself to their duties and necessities. His homily, like his argument, is inwoven with the golden thread of devotion; and the smooth flow of the epistle breaks ever and again into the music of thanksgiving. The apostle resumes the words of self-description dropped in chapter iii. 1. He appeals to his readers with pathetic dignity: “I the prisoner in the Lord”; and the expression gathers new solemnity from that which he has told us in the last chapter of the mystery and grandeur of his office. He is “_the_ prisoner”--the one whose bonds were known through all the Churches and manifest even in the imperial palace (Phil. i. 12-14). It was “in the Lord” that he wore this heavy chain, brought upon him in Christ’s service and borne joyfully for His people’s sake. He is now a martyr apostle. If his confinement detained him from his Gentile flock, at least it should add sacred force to the message he was able to convey. The tone of the apostle’s letters at this time shows that he was sensible of the increased consideration which the afflictions of the last few years had given to him in the eyes of the Church. He is thankful for this influence, and makes good use of it.
