There is a body of doctrine worth contending for, and there are secondary applications of those doctrines which we should not contend with each other about.
But mark it down in your mind: there is truth worth contending for. There is truth worth dying for. That is hard for our relativistic culture to understand. We might be able to imagine dying for people, but not many today consider any truths so precious they will contend for them or even die for them.
