Well, we could definitely survive as a species. Its bad enough losing tens of millions of people, and losing order makes it even worse.
In this case, I believe that even though most humans will stick to their religion and beliefs cause it gives them peace of mind, people will put religion aside when it comes to common work and shared survival.
No one in such a situation would let their religion out weigh the survival of an entire race.

Well to sum this up, I believe the death of tens of killions of people is a terrible thing, yet we won't run out of our supply of thinkers.
We will always have people capable of re-building society in terms of technological advancement and religion, as well as art and everything else you mentioned. It would be hard, near to impossible, but if the survivors really care for their race and lives of future generations, they would put together their efforts to protect our society from falling over the edge of doom, and prevent future generations from having to re-live the original chain of advancement that humanity followed from the stone ages until today.
Of course if it were to happen that we lose our league of supreme thinkers, in the case that said catastrophy lead to more death then you mentioed, humanity would be back in the stone ages.
What would be different in this case is that we would know our capabilites. Stories of our capabilities would be passed down through generations, then it would depend on our effort:
1- If we were to raise a thinking throttled generation, said capabilities would immediately be put into action, and we wouldn't be far from following in the paths of those before us, again in terms of technological advancement.
2- If we were to leave the world as is, and only hope for the best, stories of what the human kind is capable of in terms of science and development would be passed down as, well, merely stories, and would start fading until they reach a point where flying and reaching the moon, even projecting digital images and storing information and data in electronic units would be myths.
If we think about this, it gets us thinking. How can we be sure that this hasn't happened in the past. How can we be sure that humans in the distant past didn't have halograms or could fly to the very far extents of the univers. What is to say that people and generations before us didn't land on mars, and leave the Milky Way ?
What if they too had faced such a catastrophy, that has lead us to what we are today, possibly far behind past generations in science and development ?
That being said, religion and art won't be a problem. Unlike technology, which is created by the few and is left to be simply used by the many, art and religion weren't created. They are the very essence of our existance as humans. The very components of beliefs and creativity that make us what we are in nature, living thinking, and feeling organisms.
Although art and religion have representatives around the world, they are not bounded in these people. No, art and religion are part of our daily lives, and as such, between us live people who know more about art and religion than even those who idol them !! This is what keeps them safe.
Wooh, a long speach there. I hope someone reads it, took quit a while to write !
