Those who love their dream of a Christian community more than they love the Christian community itself become destroyers of that Christian community even though their personal intentions may be ever so honest, earnest and sacrificial. God hates this wishful dreaming because it makes the dreamer proud and pretentious. Those who dream of this idolized community demand that it be fulfilled by God, by others and by themselves. ... Do not meddle in what is not your providence. Do what is
given to you, and do it well, and you will have done enough. Live together in the forgiveness of your sins. Forgive each other every day from the bottom of your hearts.”
- Dietrich Bonhoeffer
"New fractures are forming within the American evangelical movement, fractures that do not run along the usual regional, denominational, ethnic, or political lines. Couples, families, friends, and congregations once united in their commitment to Christ are now dividing over seemingly irreconcilable views of the world. In fact, they are not merely dividing but becoming incomprehensible to one another. ...
The evangelical movement today is dividing into separate communities that still hold some moral and theological commitments in common but differ dramatically on their sources of information and their broader view of the world. Their informational worlds have little overlap. They can only discuss a narrow range of topics if they do not want to fall into painful and exasperated disagreement."
- Timothy Dalrymple, CEO of Christianity Today
Satan always hates Christian fellowship; it is his policy to keep Christians apart. Anything which can divide saints from one another he delights in. He attaches far more importance to godly connection than we do. Since union is strength, he does his best to promote separation.
- Charles Spurgeon
 
I have never yet known the Spirit of God to work where the Lord's people were divided.
- Dwight L. Moody
 
On the essentials, unity. On the nonessentials, liberty. In everything, charity.
- Philip Melanchthon
 
Mere mental assimilation of these truths cannot withstand temptation, however. The revelation of God is positively essential. The Spirit of God must reveal how we are in Christ and how we are united with Him in one.
- Watchman Nee
 
God cares nothing about our manmade divisions and groups and is not interested in our self-righteous, hair-splitting, and religious, man-made formulas and organizations. He wants you to recognize the UNITY of the body of Christ.
- M.R. DeHaan
