Is the God of Christians the God of Abraham, Isaac, and Jacob? It is an undeniable fact that among the pages of the biblical books of the Old Testament, especially in those of older composition, there are episodes of war and violence that are far from our modern sensibility. This has drawn criticism from many thinkers, including the philosopher Bertrand Russell, who refuse to consider these documents a revelation of God. The author invites us to consider the stratigraphy of those texts and divine pedagogy, progressive and in line with humanity's evolving rhythms. This leads to a more adequate understanding of customs, episodes, and texts.
