The fourth basis for unity found in these verses is a common calling to fellowship through a specific exhortation of Paul. The basis for that fellowship is in verse 9…”His son Jesus Christ our Lord”. That is an important reminder in light of the problem Paul addresses in verses 10-17, a problem that the church struggles with today. Rather than focusing on the core of our beliefs based on the miraculous life of our Lord, we use “surrogate people” to define us. Does this sound familiar? I am of Paul, I am of Apollos, and I am of Peter. Or I am of …(name a megachurch pastor or teacher). So often we create false divides over personality, method or model in identifying with a movement of faith. When that happens we limit our ability to reach out in a united way. There is some comfort in being part of a ministry that “fits us”. But Paul reminds us not to become too comfortable with style. Rather become comfortable with the truth, “to preach the gospel, not in cleverness or speech, so that the cross of Christ would not be made void” (verse 17).
