“And let the peace of the Messiah, to which you are also called in one body, control your hearts. Be thankful.”
Paul writes of the “perfect bond of unity” which is love. He calls us to allow the peace of Christ to control our hearts. With Christ’s peace and His love, how can we not be united? What causes divisions in the body of Christ? Differing views of our Lord? I rather doubt that.
Divisions are caused by earthly things which are sometimes labeled ‘spiritual’ — usually by which church we attend or refuse to attend, whether we sprinkle or immerse for baptism, whether we call the Lord’s Supper the Eucharist or Communion, whether Mary is the Queen of Heaven or the virgin mother of Jesus, whether we use only the King James Version or we like The Living Bible, whether we speak in tongues or remain quiet in prayer, whether we respond to the ‘altar call’ or confess our sins to a priest, whether we believe in ‘laying on of hands’ or in modern medicine, whether we believe in predestination or free will, and so forth.
Rather than argue or fight over these sometimes important issues, Paul calls us to “accept one another in love, diligently keeping the unity of the Spirit with the peace that binds us. There is one body and one Spirit — just as [we] are called to one hope at [our] calling — one Lord, one faith, one baptism, one God and Father of all, who is above all and through all and in all.” (Ephesians 4:2-6)
The key element is the unity of the Spirit which is due to our calling and to the one faith we share. Focus on the Holy Spirit who unites us. For we are the temple of the Living God.
