It's good to keep in mind both the private reality spoken about by Bultman and the public reality talked about by Moltmann since they both influence each other. There can't be a public reality unless there is a collection of private realities... and what the public thinks impacts what the individual is exposed to, so they are very entwined.
Of course, what individuals and the public accept can be very off base; case in point is the rapture theory. One person postulates something, and another and another believes it until the theory snowballs.
Our warped perception shouldn't be taken as the Truth, and to do that causes us personal pain. For instance if someone tells you something negative like you are stupid, it is their perception. If you believe them, their perception becomes your perception. Despite the fact you might be Einstein. Additionally, circumstances can change- you might be uneducated, but have the potential to develop into a great thinker if that is trait is nourished, which it won't be if you don't think you have what it takes and nobody else does either.
That's why it's important not to get too existential about things. Jesus is the Way the Truth and the Life for a reason; people are always equating what they think wih what is the ultimate truth. And we must quest after His truth, or we will always be a little or a lot off target.
