To the church of God that is in Corinth, to those who are sanctified in Christ Jesus, called to be saints, together with all those who in every place call on the name of our Lord Jesus Christ, both their Lord and ours
There is one body and one Spirit, just as you were called to the one hope of your calling, one Lord, one faith, one baptism, one God and Father of all, who is above all and through all and in all.
A priority which ought to mark every church is the desire for unity among all of God’s people in Christ, among all the churches. This is a difficult task since so many churches are given to an independent mindset with more or less the idea that only churches of their kind are truly Christian, or at least are the most sound and authentic to the Christian faith. That plays right into the hands of the spiritual enemy, actually coming from its hands as well.
A church is not worth its salt which fails to make unity within its own congregation a priority, and makes expression of the unity all have in Christ a priority as well. Decades back, ecumenical for me was a dirty word. Instead, we ought to downplay our differences as much as possible, and highlight our agreement, indeed our oneness in Christ. I would think on the ground that means churches should participate in ecumenical associations: Protestants with Catholics with Mennonites with Baptists with Pentecostals with the Orthodox and so on.
The cosmic powers of this present darkness along with sin, death and “the flesh” are out to divide and destroy. Christ by the Spirit is present to redeem, save and heal. We can hopefully learn to appreciate our differences as distinctives to be brought into the whole. Yes, we have our different theologies, and that often seems to make the push for unity strange at best, and certainly strained and sometimes it can make it seem worse than that. But we can learn much from each other if we can look past our differences. Without thinking we have to be in complete agreement. It is only in and through Christ that complete unity will be found, and completely so at his return. Until then we’re to seek to find unity where it may be found by the Spirit in and through Jesus.
Especially the first sentence of the last paragraph was written under the influence of Tim Gombis’s excellent book, Power in Weakness: Paul’s Transformed Vision for Ministry. My application of that, so that what is amiss here cannot be blamed on Tim.
