I can’t recommend enough Robert Lund’s book ‘The Way Church Ought To Be’ it is a like the encyclopedia on relational Christianity. It is available at our online store! (How’s that for a cheap commercial). No really, this guy has done all the heavy lifting regarding the Greek translations and the intended meanings of the original writers. He has it indexed by person, scripture, and general topics so you can quickly look up a verse that someone may toss your way and be able to wrap your brain around it without having to have a degree in Hebrew and Greek.
I have used it frequently when challenged with those bulwark texts that RI’s hang their hierarchy on.
