‘And he is the head of the body, the church.’
This may be the detail in Paul’s description of Jesus that is the least thought about, although much is said about it in ecclesiastical and denominational disputes. No doubt, such disputes are important when error is advocated. But what would be the significance of saying this about Jesus to a Christian group in Colosse in the first century?
One point is that it is a reminder that believers who live in not-so-important places belong to the same church as those who live in what may be regarded as important places.
A second point is that every believer is equal as far as their union with Christ is concerned. Living in Colosse was not a reason for imagining that less divine guidance and less divine power and less divine grace would be available for them in their gospel witness and church growth. They would not be able to have the same number of committees or activities, but they had the same Christ helping them to live the Christian life, to be salt and light in Colosse.
A third detail is that the Christians in Colosse will share with other Christians in the future eternal glory that Christ will give to his church. The Christians in Colosse were included in the prayer of Jesus recorded in John 17 concerning those who would yet believe in him. Colosse may not have been much in comparison to nearby Laodicea or faraway Rome, but Christians in all places have a great future because they are part of Christ’s church.
Later on in this letter (2:19, Paul uses the same illustration of the church as a body and says that every part receives its sustenance from Christ the head. He knows whatever spiritual provision is needed at every moment by each person in his church, and he provides it. Living in Colosse may have caused the inhabitants of the town to miss out some things, but there was no reason why the members there of Christ's church should lose out on his blessing apart from a decision by any of them to go after something else instead.
