AHC and WI: Religion very important worldwide in the 21st century

With a POD of 1815 (the Congress of Vienna), have it so that the vast majority of people globally consider religion an important part of daily life. Most crucially, make religion still a predominant factor in every day life in the west (Europe, the Americas and Australasia).

You must:
  • Have less than 5% of the world population being irreligious
  • Have religion and politics closely tied in the majority (75%+) countries, including the European powers and the USA
  • Have Christianity as the largest religion, with Islam as second (as in OTL)
  • Have major political movements in Christian countries for the revival of Christian theocracy
  • Have the majority of people in Christian countries attended church at least once a week

You should try to:
  • Have the world be politically less advanced and more conservative
  • Have worse relations between countries of different faiths, and better ones between those of the same faith (perhaps a Catholic League, for example?)

You could (for bonus points):
  • Still have a Jewish state come into existence somewhere in the world (you can choose where, as long as it is plausible)
  • Have atheism be considered abnormal and frowned upon in the west (more so than it is in OTL)

As for the WI side, how would our world be if religion was considerably more important? What would daily life be like, and what would the politics of the world be like?
 
what would need to take place would be a total repudiation of the rabid atheism that was displayed in the French revolution, possibly harsh penalties laid on any individual or group who attacks religion. Put the blame on starting the bloodbath that swept Europe since 1789 on atheism. Then continue pound in to each new generation that atheism leads to chaos suffering and nearly incalculable death, by teaching how essential religion is. Then if something like communism would rise fearing another 1/4 century brutal war and mass social upheaval the atheistic movement would be crushed.

by the way I would be love a world that was much more religious.
 
I was going to make a new thread with this question but realised I've asked it here before, so I'll just bump this one, hope for some more answers.
