If any hope for unity (even within Restoration churches) is forthcoming, it will most likely occur because of individual effort rather than as a group.
We have sat around waiting for some sort of unification plan to unfold for years without success. This statement will probably get me in hot water with a few elders, but when you go for years and years with little, if any, plan to rectify our disunity problems, seldom hearing a word about our need for unity from the pulpit, or privately for that matter, I can't help but suspect that many of our leaders are too busy protecting our fenced-in position, and see unity as a low priority endeavor.
Perhaps this approach is oversimplified; but as individuals within a church, we need to find ways to seek unity, even when our church leadership apparently disagrees. It would be great to have our elders leading the way to unity, but my experience (along with many of my brothers and sisters in other RM churches ) give no reasons to believe unity is something being discussed, or pursued, by our leaders.
Rather than waiting for our "church" to initiate (which seldom happens) some sort of unity seminar (or whatever) focusing on drawing divergent churches together, we need to take the proverbial bull-by-the-horns, and within our own hearts have the courage to unite (especially with those we share RM roots) with our brothers and sisters who sport a different name on their "church sign."
I don't know how others approach this disunited mess, but when I talk to my friends in churches with different names on their signs, we discuss our positive feelings about our relationship to God, not accusing each other of our failings, but accepting each other as a part of the Lord's body with love, knowing we are truly brothers and sisters united in His cause.
Unity is certainly an attainable goal that Christians can strive toward without attempting to create every church into a carbon copy of what we think it should be, but with the realization that none of us are perfect (including us,) and we can all dwell together in peace and love fully recognizing each other as children of God; thus brothers and sisters.
