Death of God theology

statement by German philosopher Friedrich Nietzsche

atheism based on the philosophical legacy of the teachings of Jesus Christ

theological-philosophical movement explaining the rise of secularity and abandonment of traditional beliefs in God

Postchristianity is the situation in which Christianity is no longer the dominant civil religion of a society and has gradually assumed values, culture, and worldviews that are not necessarily Christian. Post-Christian tends to refer to the loss of Christianity's monopoly in historically Christian societies to atheism or secularism. It does not include formerly Christian societies that now mostly follow other religions like Islam, such as parts of the Balkans and the Middle East.
