Critics of traditional Jewish and Christian belief have also argued that inconsistencies undermine the value of scripture. The deist minister Joseph Barker, speaking in 1854, described the Bible as "the most inconsistent, the most monstrous and blasphemous representations of God that can possibly be conceived by the human mind" and argued that "The book that contradicts science and contradicts itself is a book of no authority whatsoever".[7] A modern Islamic critic writes that if the Bible can be shown to be inconsistent, "then those who preach the Bible and read the Bible must seriously reconsider their source of information concerning their faith."[8]
