Christ also is the head of the church, being Himself the savior of the body…we are members of His body. Ephesians 5:23, 30
Letter writing was laborious business in the days of the apostle Paul, before typewriters were invented. That is why he asked different churches to share the letters he sent them, just as we are reading and receiving a blessing form those same letters today.
Two of his letters are much alike, those to the Ephesians and to the Colossians. They are so similar that they are often called twin epistles. An interesting exercise is to sit down and underline the verses that are almost identical in the two.
The difference between the two (for most twins have differences) is that Ephesians looks at the Church as the blessed body of Christ, and Colossians looks especially at Christ, who is the head of the body.
The fact that Ephesians and Colossians have a great deal in common, and that we are blessed by those same letters today, shows that the chief characteristic of the Church of Jesus Christ is its unity. There are Christians today whose language we cannot understand if our life depended upon it. The Christians of some countries are radically different from us, in their way of life. Yet for all our differences, Paul says that “there is one body, and one Spirit, even as we were called in one hope of our calling; one Lord, one faith, one baptism, one God and Father of all, who is over all, and through all, and in all.” (4:4) Notice exactly how many “one’s” there are in that passage–seven, the complete number, the number of churches in Christ’s candelabra in Revelation.
In these days when there is so much talk about church union, it is wonderful to know that the true Church of Jesus Christ always has been united. It has different parts, just as there are different parts to our body, but it is always and absolutely one.
