According to Roman Catholic biblical scholar Raymond E. Brown, this approach found expression in Dei verbum, one of the key documents adopted at the Second Vatican Council, which stated that scripture teaches "solidly, faithfully and without error that truth which God wanted put into sacred writings for the sake of salvation,"[26] meaning that Scripture is inerrant only "to the extent to which it conforms to the salvific purpose of God,"[27][28] without necessarily being reliable on matters such as paleontology or political history; this view is challenged by some conservative Catholic scholars.[29][30]
