If you want to understand the thinking of the fathers of the early church, you have to be conversant with the thinking of classical antiquity. One does not come up with sophisticated intellectual tools all by oneself. The Christian thinkers of the early church realized and appreciated this, if they did not always give credit where credit was due. If you want to understand the thinking of the theologians of the middle ages, you need to be familiar with the philosophy that was employed then. You have to understand the Christian Platonism that arose in the first few centuries and was dominant until the twelfth. You will have to understand this Christian Platonism as the context in which a more taxonomically versatile and methodologically explicit Christian Aristotelianism arose in the thirteenth century. If you want to understand the thinking of the Reformers and of Reformed Orthodoxy, you still need to be conversant with the philosophical commitments of medeival theologians because there are more continuities than discontinuities. Richard Muller is eminently conversant in the philosophical approaches and distinctions that inform the theology of the reformation.
This lecture is nothing new, but it was to me, and very interesting. Reformed Protestants with a strong commitment to the authority of confessions have been expressing disquiet about Jonathan Edwards, and this has puzzled me. It is no doubt part of the unease with American Evangelicalism, of which all American Reformed Protestants are in some way a category. They wish always to stress the differences. Jonathan Edwards’ star is bright in the firmament of American Evangelicalism.
Richard Muller argues that Edwards’ determinism is not that of the calvinism of the Reformed tradition. If I understood correctly, he claims that Edwards’ departure consists in claiming for causality a much reduced definition, one in which there is little more than an efficient causality and not the full range of causality the Christian Aristotelianism of Reformed Orthodoxy accepts. The result is that rather than having all the necessary distinctions to allow for free choice, fundamental indeterminacy of the will, and faculty psychology, Edwards develops in a more Amyraldian way, taking as his philosophical forebears Hobbes and Locke.
