Query: 1 of 7 books I recommend to every leader

I sometimes jokingly say this book should be titled, Free to Disagree Agreeably. I recommend reading this book together with One Lord, One Faith by Rex Koivisto. Koivisto's book differentiates between what the author calls "the core of orthodoxy" over against secondary and tertiary points of doctrine and practice.
