Augustine, Anselm, and Aquinas all wrote about the issues raised by the Euthyphro dilemma, although, like William James and Wittgenstein later, they did not mention it by name. As philosopher and Anselm scholar Katherin A. Rogers observes, many contemporary philosophers of religion suppose that there are true propositions which exist as platonic abstracta independently of God. Among these are propositions constituting a moral order, to which God must conform in order to be good. Classical Judaeo-Christian theism, however, rejects such a view as inconsistent with God's omnipotence, which requires that God and what he has made is all that there is. "The classical tradition," Rogers notes, "also steers clear of the other horn of the Euthyphro dilemma, divine command theory." From a classical theistic perspective, therefore, the Euthyphro dilemma is false. As Rogers puts it, "Anselm, like Augustine before him and Aquinas later, rejects both horns of the Euthyphro dilemma. God neither conforms to nor invents the moral order. Rather His very nature is the standard for value." Another criticism raised by Peter Geach is that the dilemma implies you must search for a definition that fits piety rather than work backwards by deciding pious acts (ie. you must know what piety is before you can list acts which are pious). It also implies something can not be pious if it is only intended to serve the Gods without actually fulfilling any useful purpose.
