Descartes was pretty devout. He was raised Catholic but became a believer in Jansenism, which was an offshoot of the Catholic Church in the 1600's. Jansenism was actually heretical as far as the Church was concerned, though, because it emphasizes predestination as opposed to free will.
No, he believed in God.
