There is a hard limit to how far you can go as a rationalist without scientific literacy; and there is similarly a hard limit to scientific literacy without cultivated rationality.
But they do not share a 1:1 correlation, certainly.

This is vague and sounds false. I don't know where you're getting the idea of a hard limit - as Desrtopa noted, plenty of scientists more studied than you or I believe in God. I especially don't know what you mean by 'far'.
