Abstract: | The goal of this paper is to show that a simple, set-theoretic manipulation of symbols can be used to model or signify Trinitarian relations as presented by Aquinas in his Summa Theologiae. More specifically, by assigning certain mathematical symbols to specific terms in his theology, his careful use of terminology and his theological arguments can be represented and preserved since the structure of the symbols will be designed to reflect the structure of his grammar in a tight, succinct format. Advantages of this modeling include brief symbolic summaries rather than lengthy prose, as well as a promotion of ecumenical dialogue through a language (mathematics) accessible to all faiths. |
