Present-day religions like Christianity and Islam still retain considerable social influence.

More modern religions, which have a narrower scope than do integrated belief systems, can still wield significant influence in the social order.

Christianity continues to exert a major influence on people's attitudes on issues ranging from homosexuality to family values in entertainment.  Certain Christian groups have also been successful in altering how science is taught in our schools, requiring in some areas that creation be presented as an alternative to evolution.  These forms of Christianity are currently enjoying a resurgence.

Another modern religion, Islam, is even more strongly resurgent than Christianity.  It has already formed the basis for the overthrow of more than one social order, and it is highly capable of more.   We may miss the point by characterizing these revolutions as representing just Islamic "extremism."  In a sense, Islam appears to have always been a system of social order—perhaps even more so than one of abstract theology or cosmology.
