Abstract
I argue here that, due to the influence of Greek philosophical ideas (such as the depreciation of time and change, and the glorification of independence and unqualified omnipotence), Christianity and Islam developed in directions foreign to the religious vision of their founders, leading ultimately to the present antagonisms between them. A 'philosophy of organism' - which sees time as cumulative, relations rather than substance as basic - can, however, help to reinterpret the insights of Jesus and Mohammed, and show that humanity's primary responsibility is to care for the creatures which the Eternal One has called into being.
