Technically Christianity is more of a pantheistic religion, when you take the Trinity into account, not to mention the worship of Saints in many denominations. I am not actually a militant atheist, as some of my posts here may suggest. I consider myself to be an agnostic. I can see the value in spirituality and mysticism. But Abrahamic religions in particular have always been just as much political philosophies as spiritual ones. In the "west" they have largely been pushed aside from any sort of political power by Enlightenment values like separation of church and state. In the muslim world even the most laid-back "democracies" are basically theocracies, with an endorsed State religion, the Quran and Islam being enshrined in constitutions as the primary guiding documents of governance.
Even in the US, which I would characterize as one of the most bible thumping nations of the "western" world, religion is largely given lip service to, mostly during election runs. This may get me some flak, but when it comes to politics Americans have a tendency to unrationally worship a rather different document, i.e the Constitution. Dominionists for example are a small fragment of right-wing extremists without much support or political pull, yet they are the closest in political ideology to the average muslim country.
(P.S: notably absent from that map is Israel, which DOES have a State Religion, no matter how vaguely they sidestep around the definition.)
