Can religious people be nihilists?

What a silly question, you might ask. When nihilism represents the rejection of any sort of deity or spirituality, when it asserts that morality and law are subjective, it is clear that nihilism and religiosity are incompatible.  Even more, since all nihilists are by necessity atheists, how could a religious person be a nihilist and at the same time an atheist?

The logic does not work both ways, however. Remember that atheists are not necessarily nihilists, and some atheists have some sense of spirituality, but they give credit to the fact that their make-believe is just that, make-believe.

Documentary about Deborah, a thirteen-year-old born and educated in a theist family:

Documentary about 13-year-old Deborah Drapper, who — unlike other British teens — has never heard of Britney Spears or Victoria Beckham. She is being been brought up in a deeply Christian family and her parents are trying to make sure she and her ten brothers and sisters have grown up protected from the sins of the outside world.

Deborah is a bright, confident girl who has big ambitions for her life, and the film spends a summer with her as she ventures out into the world to see what life outside her family could be — as she starts putting her beliefs forward to a wider audience.
