I get what you're saying, and I generally agree with you. But I just want to clarify that a theological leap of faith is very different than a scientific one. This is the kind of comparison that groups such as Christian fundamentalists like to exploit (not saying that's your view, just giving an example).
The phrase 'leap of faith' applies to both science and religion, it's just the context that is differing.
In religion it would mean believeing in a literal interpretation of the Bible, believing a virgin gave birth, believeing Jesus performed miracles, and that he died and was resurrected, the earth is 6000 years old, etc.
In science (and I'm referring to the hard sciences) a leap of faith is made following the scientific method - formulating a hypothesis, conducting testing and experimentation, observation, evaluation of data, and ultimately re-evaluating the hypothesis. And where I believe they differ is that science is conducted with the intention of demonstrating or proving a fact/truth that was previously unknown. In that regard, religion has no track record.
(I'll go back to being a defensive scientist elsewhere now
)
