From birth my religious thinking was shaped and nurtured (warped might be a better term) by a church believing they alone represented the true church on earth. Things were simple in those days; identifying the Lord's church was as uncomplicated as reading the sign over the entrance into the building, if it said CHURCH OF CHRIST it was THE church (although this wasn't always true, some churches that wore the proper name were lost,) any other name written on the sign revealed an apostate church where I had no brothers and sisters to fellowship.
One of the primary objectives of the Restoration Movement was to unite Christians; yet over the years those within the RM have splintered into dozens of separate groups where fellowship, even between churches with the same heritage, is almost nonexistent. What started out as being a noble endeavor to unite God's children has regressed to the point that we seldom, if ever, seek unity with other Christians. Many in the COC honestly believe there can be no unity unless those who disagree with us completely drop their cherished beliefs and fully adopt our viewpoint-we are always right, and your usually wrong!
The religious world is not blind to the failure of the RM to achieve unity, and by our actions it's easy to see that we desire unity only on our terms. In order to have Christian unity we must find a way to show other Christians we truly desire their fellowship without demanding anything of them that God doesn't require.
Since no one is perfect, even the Christian, there will be disagreements on every conceivable doctrine, and if we expect every church to fall in line with our particular beliefs we will always be disappointed. Believe it or not, many people in what many of us might call false churches, actually are honest in what they believe, even if their wrong. Many in the Church of Christ are also honestly wrong in what they believe (this may be a shock to some in the Church of Christ.)
Some questions to ponder:
1. What will those in the COC concede for the sake of unity, and what do we expect other groups we discuss unity with to concede?
2. How well can we accept change after years of believing we alone have the perfect pattern for the church?
3. Do we really expect other groups to throw away their beliefs and adopt our viewpoint?
