The origin of being on the same page is not fully clear. However, it is believed that this expression developed at some point during business meetings with executives. Rather than try to undermine one another, companies function best when leadership teams are on the same page. Churches often develop mission statements so that when questions arise, pastors and elders can get back on the same page as well.
Clothe yourselves therefore, as God’s own chosen ones (His own picked representatives), [who are] purified and holy and well-beloved [by God Himself, by putting on behavior marked by] tenderhearted pity and mercy, kind feeling, a lowly opinion of yourselves, gentle ways, [and] patience [which is tireless and long-suffering, and has the power to endure whatever comes, with good temper], Colossians 3:12.
Unfortunately, there has only been one reported church that has sustained unity, Acts 2:42-47. While great awakenings of the18th and 19th centuries breathed new life into churches, unity did not last. According to Luke who served as a first century historian, traveling with Paul on several missionary trips, the early church-maintained unity by eliminating poverty. Rather than take up a weekly offering during a worship service, wealthy Christians sold their own possessions to provide funds for every emergency.
Be gentle and forbearing with one another and, if one has a difference (a grievance or complaint) against another, readily pardoning each other; even as the Lord has [freely] forgiven you, so must you also [forgive]. 14 And above all these [put on] love and enfold yourselves with the bond of perfectness [which binds everything together completely in ideal harmony], Colossians 3:13-14.
The apostle Paul is blunt about what is necessary before unity can be achieved. This requires grace, love, patience, and selflessness. Apparently, early Christians practiced the words of Philippians 2:1-5 by taking on the attitude of Jesus. When church leaders emulate unity, members of a congregation start to follow. However, when unity is merely a spoken word without any action, getting on the same page of unity remains an unfulfilled goal.
