Unity is Bloody

"We moderns think unity is easy. We only have to sit down and talk and everyone will rise from the conference table filled with the glow of love and peace.  The Bible knows this is a delusion.  Unity is costly, achieved only by the anguish of crucifixion.  Unity seems easy for us only because of the blood of Jesus, and the blood of many martyrs since."  (Peter Leithart, Behind the Veil, p. 34-35)
