"Nothing can perfect unity in the church but the spirit of Christlike forbearance."
Unity of what? Unity of denominational membership? What is the characteristic of this ambiguous unity? 
 "Can two walk together, except they be agreed?" Amos 3:3

Unity in attending the same church & saying "Happy Sabbath"...but sitting far apart from each other in the pews and at potluck?

What about churches where the pastor and most elders are against WO but the women are elders, the church has guest women speakers & Sabbath school adult teachers?

What are the youth supposed to think?
