Abstract: While Boethius's definition of the person, 'an individual substance of a rational nature', plays a significant role in Christian theology and anthropology, its reception is by no means uncritical. In the last hundred years, virtually every element in it has been critiqued by theologians and secular scholars. Nevertheless, its context suggests that his understanding of the person is potentially far richer than supposed. This paper places Boethius's definition of the person in its historical framework and in the context of his own thought, especially Contra Eutyches and Consolation of Philosophy, in order to demonstrate that despite shortcomings, it represents a dynamic and holistic characterisation of the person.
