I think the assumptions that drive many of the theories, postulates and hypotheses out there become almost concrete, until disproven.
For some theories, I would agree with this, for others, it is pretty soft. Scientific theories exist along a continuum in my opinon...from "probably unlikely" to "almost scientific law".
String theory, for example, is very soft. It is simply an attempt to explain how quantum mechanics work. The math makes sense, and it
could explain quite a bit, but evidence for it is lacking. It is very likely another Einstein may come along and blow it out of the water.
Evolutionary theory is another, on the other end of the spectrum. Is it true that the theory could be wrong? Sure, but if it is, we must account for 150 years of scientific data....and mother nature sure has a lot of explaining to do. The specifics of the theory are still debated, and there may even be a fundamental flaw in the theory. But ask yourself what the chances are that evolution of species didn't happen
in some form on this earth? It is effectively zero.
Your point would be that science reassesses itself when proven wrong. That's the case for everyone and everything.
How does this fit within the purview of religion, when it is ultimately a matter of faith? I would say that with science it is a huge liability to be certain and to be wrong. This is why there are so few scientific laws. With religion, it seems to be the other way around. The believer simply knows they are right, by order of faith, and will not change unless it becomes impossible to defend anymore...and even then the pre-held belief is simply modified to fit within the common sense that has been established (enter intelligent design).
Admittedly, I would venture to guess you and others on here believe you could be wrong, and are open to compelling evidence and reasons, and I respect that. But overall this is the exception rather than the rule. I am not going to hold my breath that anything will come along to change your views on spirituality and the efficacy of Christian belief.
The difference for the majority, in my opinion, is when "faith as a virtue" is used as justification for tightly held beliefs, it is difficult to come up with any evidence to the contrary the believer will see credibility in.
