The Bible speaks of churches of Christ. People speak of churches of Christ. Sometimes they aren't the same thing. The former is always His as Jesus really is building it. The latter is suspect. Both might be the same; but not likely.
All of mankind needs to know of the church Jesus is building and let God add them...just as He always has since Acts 2. The kind of church we know where we don't use instruments like the Methodists and have communion every week, unlike the Baptists, does not make us the true church.
Church of Christ was never a brand name. The New Testament is silent regarding any evangelist urging potential converts to visit a local Church of Christ as if it better designed than the Presbyterian one as we know competitiveness today. The direction offered was toward Jesus.
I love and want to be a part of the church Jesus is building. The denominational Church of Christ is not what we see in the scriptures. We must continually help one another lean to the one and avoid the other. It isn't a we/they. No one is exempt. We have let in man-made doctrines claiming them to be all from God. They aren't. We picked many of them up from the very denominations we criticize.
