The brutal murder of a journalist James Foley by the ISIS militants has rightly been widely condemned. But in doing so, president Obama was being disingenuous when he said that “No faith teaches people to massacre innocents. No just God would stand for what they did yesterday and what they do every single day.”
Massacring innocents is precisely what religions have demanded down the ages. Just look at the Old Testament of the Bible, venerated by Christians, Jews, and Muslims alike. It is full of one story after another of the murder of untold numbers of people on behalf of their god. Even now, people think that earthquakes, floods, and other catastrophes that kill thousands indiscriminately are all sent by their god with intent to kill.
Obama is right that no just god would stand for such a thing but that is because of the logical contradiction that it would entail. But the evidence from history or nature or from the holy books of religion is that the god they worship is not just.
