The spotted owl has been disappearing in the US. Originally it was believed that old growth logging was its greatest threat. But research shows that one of the owls relatives may be the problem. For the past 15 years, the barred owl has been rapidly migrating westward. Barred owls, which used to live exclusively east of the Mississippi, compete for the same food as spotted owls but are more aggressive and adaptable.
In a similar way, our greatest spiritual conflict often comes not from outside the church, but from other Christians. This was happening in the church of Corinth, and Paul took some time to address the divisive spirit that had grown in this congregation. This spirit threatened the unity of the church. Paul, with a pastoral nudge, encouraged the Corinthians to agree on the essentials and not be divided over the nonessentials. People were quarreling because they were aligning themselves with different Christian leadersPaul, Apollos, Peter, and even Christ. In creating these divisions, they were valuing their favorite leader above unity in Christ.
Paul said the one essential that should unify the church is preaching the good news. That should be our united goal as well.
