Abstract
Justice is a divine attribute to which the sacred texts of the Abrahamic religions attest frequently and to which people attach great importance. However, it is the express subject of comparatively few contemporary studies. It has been argued that this is symptomatic of a long-standing trend in Christian theology, which has tended to conceive justice narrowly, as retributive. This paper makes the case that, mediaeval theologians, from Anselm to Aquinas, address the divine attribute of justice in depth and with philosophical sophistication, viewing it primarily as God’s merciful and gracious distribution of merits and goods. It seeks to identify Aquinas’s contribution to the mediaeval analysis of this divine attribute and assess what he may have to contribute to current philosophy of religion. In particular, pointing to natural teleology, he offers more fully worked out metaphysical reasons for calling God just and considering all his works just. The existence of creatures can only be explained as an act of divine mercy, with the result that, since existence is the fundamental gift, all God’s works are merciful and just.
