I write quite a bit about what makes simple church different from institutional church. Despite these critical differences, something else is even more important: our unity in Jesus Christ. By "our," I'm referring to all Christians everywhere. We are in fact one body with Jesus as our Head. He has made us so.
Even a cursory glance over the American church landscape shows us a great deal diversity within the body of Christ. We are not all alike. There is little uniformity, even within denominations. Frankly, it's difficult to find even two Christians who agree on all points of doctrine. However, that does not mean that we are not one in Christ.
We are one in Christ because God deems it so. It is what we are positionally. Christ is our leader, and we are His followers. It is our duty to live out what we are: one body. We make a terrible mistake if we consider ourselves to be mostly different from other believers (even if we hold very different views about church). A better practice is to view ourselves as mostly the same as other Christians. All believers in fact believe in the same Gospel. This unites us.
Let's do all we can to be proactive in developing unity within the body. This can certainly be a challenge since church-related views are so different. However, there is a lot of time during the week when we have opportunity to see other Christians (at least I hope you have this opportunity). Whether it be at work, in the park, or in the neighborhood, it is our responsibility and joy to edify other Christians whenever and wherever.
We are one in Jesus. Let's live out what we are. The One who bonds us is stronger and more significant than our differences.
