“But the overall number of church-going, biblical-worldview-embracing Christians (Catholic, Protestant, Orthodox, or Evangelical) is dropping in this country.”
The overall number of church going Orthodox Christians is rising in this country. We are certainly counter-cultural though I doubt that has anything to do with the rise in attendance and conversions. If what you mean by “biblical-worldview-embracing”, however, is that mindset demonstrated by protestant evangelicals, I sincerely hope that their number among the Orthodox dwindles to zero. That parochial worldview translated into foreign policy has had a devastating effect on Eastern Christian communities from the Adriatic to the Iran/Iraq border and its missionary endeavors, really nothing more than a form of religious and cultural imperialism, have been particularly targeted at Orthodox, Oriental Orthodox and Monophysite Christian communities many of which are just now engaged in national struggles to shake off the Western poison of Communism and replace it with their ancient cultures which in great measure were formed by Eastern Christianity.
Everything the USA under Clinton and then Bush and probably Obama since his foreign policy is no different (despite his claims of change) that this effort by the “West” to bring order to the “east” has fallen hardest on Orthodox and other eastern Christians. Even the Russo-Georgian war (Which the EU just said was caused by Georgia) is based on western attempts to secure satellites in the east that has caused Orthodox on Orthodox friction.
