Is Focus On Christian Sufficient Grounds For Church Unity?

Pastor Sean Harris on SermonAudio.com suggests in a sermon nearly of the same name that the way to eliminate divisions within the church is to focus on Christ.

So what happens when that focus on Christ leads some to believe that His Eucharistic remembrance actually becomes the literal body and blood of the Savior, some that his presence is somehow contained within the elements, and yet still others simply are a symbolic contemplative commemoration?

And whose teaching is to prevail in the way Sunday School positions or slots on the deacon board are doled out when the focus on Christ leads some to conclude that He returns to retrieve His church prior to the Tribulation and others to conclude after the Tribulation?

In his homily, Pastor Harris ruminated what the church in America would be like if there were no denominations.

Provided people did not just abandon organized religion altogether, the situation would return to the upheaval characterizing the Reformation and Counterreformation if it was required that only a singular opinion would be allowed to exist within the boundaries of a unified Christendom.
