Christians (Protestants) differentiate themselves from Catholics.  Thank Martin Luther for that.  Protestant Reformation.  Back to the nitty gritty.  No more worshipping Mary, praying to Saints, donating cash to the Pope so you can get into heaven.   Now its all about confessing sins to God instead of a man in a booth, praying to God through Jesus instead of to God through a priest, etc etc ... All that standing, sitting, standing, sitting, ... latin services nobody could understand, etc ... =  "Religious".  Therefore a Christian saying Catholics seem really religious is basically a fellow who got back to the true roots of Jesus message, looking at an institution (Catholicism) which is still very bogged down in ritual and meaningless, manmade elements.  "Religiousness".  As opposed to a "Relationship" with god ...

Clear as mud?  Protestant 101 dismissed!

As for the 1 world currency that is "the mark of the beast" ... you can bet your sweet tooshie that when Bitcoin gets big .... this is going to be a HUGE focus by many in the circles of faith.  This is why I would highly recommend for anyone the least bit concerned about Bitcoins success, that you leave the "God thing" out of it.  Its already going to be labeled Satans currency.  Mark my words. http://www.ridingthebeast.com/articles/gold-money-666/ And hey ... maybe it will be just that.  As long as you don't etch your private key in your forehead or wrist, you're fine.  But you'll starve to death too.  Or get your head chopped off for non compliance.  Or get caught up in the rapture.  Whichever happens first.  

Bright days ahead!
