As of my last knowledge update in September 2021, I don’t have specific information regarding a book titled “Unity in Christ: Maintaining Church Unity in a Polarized World.” It’s possible that this book was published after that date or that it may not be a widely recognized or mainstream work in the field of literature. However, based on the title you provided; I can offer some general insights on the topic of maintaining church unity in a polarized world.1
