Lonergan on Substance and Transubstantiation

Abstract

The notion of substance has been a fundamental concept in the history of theology. While many scholars have moved away from the traditional notion, it has remained a basic element in Bernard Lonergan’s work. In his case, however, it is bound up with his critical realism, a contentious issue in itself. This article explains these issues, seeing some of their implications in Eucharistic theology and concluding with some incidental reflections of Lonergan on transubstantiation.
