I really enjoyed John Dickson's Bullies And Saints: An Honest Look At The Good And Evil Of Christian History. There is much to learn from the record of bullies and saints in church history lest we repeat their failures or fail to replicate their successes. Truly, as Solomon said, there is nothing new under the sun.
I am doing a series of posts where I cut and paste from his book. Where I fill in words, you will see [brackets]. I use ellipses for all the places where I know there is a gap, but (because of how Kindle highlighting works) I am sure there are many places where I fail to note what's written between two sentences I put next to each other. If what I post feels disconnected or clunky as you read it, that's my editing, not his writing :)
