The conclusion of your excellent review of the historical Abraham and the three great religions seemed to be that belief in Abraham might help bring Muslims, Jews and Christians closer to one another [Religion, Sept. 30]. But hasn't this been tried in vain for centuries? My conclusion: ban all these religions, cults and man-made concepts of how to worship God. Bar the different religious leaders from spreading their views as the only absolute. Mankind can always use religion as a casus belli. Forbid religions and there will be far fewer fights.
