Among British Quakers, 14.5% identified as atheists and 43% felt "unable to profess belief in God" in 2013. Catholicism Catholic atheism is a belief in which the culture, traditions, rituals and norms of Catholicism are accepted, but the existence of God is rejected. It is illustrated in Miguel de Unamuno's novel San Manuel Bueno, Mártir (1930). According to research in 2007, only 27% of Catholics in the Netherlands considered themselves theist while 55% were ietsist or agnostic deist and 17% were agnostic or atheist. Many Dutch people still affiliate with the term "Catholic" and use it within certain traditions as a basis of their cultural identity, rather than as a religious identity.

Lewis's argument, now known as Lewis's trilemma, has been
