1) There are a number of helpful topics by which one might examine some of the differences and similarities across the centuries from the Medieval period up through the Reformation, and each allows a set of concerns to come into focus. The related questions of the nature of grace and whether a person might merit salvation is one such helpful pair of topics. These questions, conjoined from the Middle Ages through the beginning of the Reformation, begin at a point where they are very much tied up with ontological questions about the relationship between beings and God, and about the character of knowledge, in general, and the nature of theological knowledge, in particular. Do beings naturally participate in God to some degree (i.e., in a manner according to the nature of a being), or are they wholly separate, radically contingent and entirely superfluous ephemera of the divine will, thoroughly alien in their being to divinity, without a native point of contact? Is knowledge –even secular knowledge– a participation in divine knowledge, or is it a navigation of singularly unique particulars through signs? Is grace participation in God, likeness to God, favor from God, divine acception, or else some or even all of these? Is this grace something which people are able to know they are partaking of? The Nominalists’ and Reformers’ answers to these questions illumine some of the crucial elements that come to characterize the Modern period, our secular cultural condition. We will begin with Thomas Aquinas (1225–1274), briefly noting the Ockhamist/Nominalist tradition which follows shortly after him, then we will move through these questions in Martin Luther (1483–1546).
