If a person doesn’t like propositional statements & thinks such are more or less a waste of time & that person would rather not be part of a Christianity like that, perhaps I can point them to what Martin Luther said:

There is some truth to this as well:

so great is my dislike of assertions that I prefer the views of the sceptics wherever the inviolable authority of Scripture and the decision of the Church permit. … And as a matter of fact, I prefer this natural inclination to one I can observe in certain people who are so blindly addicted to one opinion that they cannot tolerate whatever differs from it (The Free Will,trans. Ernst F. Winter, 6).

I think we should differentiate between debates and statements within the church about non-basics (e.g. free will vs. predestination) and debates and statements between Christianity and the outside world about the fundamentals of the faith: Jesus is the risen Messiah, Lord of the world. After all, Christianity is not Christianity without the Christ. Let’s hope we all do not go off in, for example, John Shelby Spong’s dirrection.
