"The point is that we have all moved on, and in a big way, since biblical times. Slavery, which was taken for granted in the Bible and throughout most of history, was abolished in civilized countries in the nineteenth century. All civilized nations now accept what was widely denied up to the 1920s, that a woman's vote, in an election or on a jury, is the equal of a man's. In today's enlightened societies (a category that manifestly does not include, for example, Saudi Arabia), women are no longer regarded as property, as they clearly were in biblical times. Any modern legal system would have prosecuted Abraham for child abuse. And if he had actually carried through his plan to sacrifice Isaac, we would have convicted him of first-degree murder. Yet according to the mores
of his time, his conduct was entirely admirable, obeying God's commandment. Religious or not, we have all changed massively in our attitude to what is right and what is wrong."
