Full Idea
There has never been a single legislator who, in proposing extraordinary laws, did not have recourse to God, for otherwise they would not be accepted, since many benefits known to a prudent man do not have evident persuasive reasons.
Gist of Idea
All legislators invoke God in support of extraordinary laws, because their justification is not obvious

A Reaction
It does seem to be an important role for God and state religion, to give support to decisions and laws which might not be intrinsically popular.
