"The US is at one and the same time one of the most fiercely secular and aggressively religious countries in the western world. The nation's two most sacred texts are the constitution and the Bible. And when those who interpret them disagree, the consequent confusion resonates way beyond Montgomery.
This is a country where 11 states, including Alabama, refuse to give government money to students who major in theology because it would violate the constitution, and where nativity plays are not allowed in primary schools. It is also a country where, a Harris poll showed, 94% of adults believe in God, 86% believe in miracles, 89% believe in heaven, and 73% believe in the devil and hell...
These two competing tendencies produce some striking contradictions...So while there is a constitutional, albeit contested, barrier between church and state, there is almost no distinction between church and politics...
America's religiosity is not something it shares with even its few western allies, let alone the many countries that oppose its current path. Yet another poll shows that among countries where people believe religion to be very important, America's views are closer to Pakistan's and Nigeria's than to France's or Germany's."
IMHO, I would suggest that a very large percentage of people who believe in God, miracles, God's special protection of America etc. have got very little knowledge about the subject, outside of what is said in church. Belief without knowledge is absurd - you might as well believe in the Easter Bunny if you don't think about what you believe in. IMHO, being able to quote Biblical verses is neither necessary or sufficient for being a good Christian, and in fact the dogmatic assertion of religious "truths" is one of the main problems that the US currently has.
