This paper is a qualitative comparison of two seminal academics in the field of Catholic education: Gerald Grace and John Sullivan. The selection of Grace and Sullivan is a result of their respective interdisciplinary approaches to the study of Catholic education, each has offered a significant research contribution to their chosen field. Incorporating evidence from a large pool of their research, as well as corroborating work from other scholars, my paper aims to assess the ways in which Grace and Sullivan understand the present state and challenges faced by Catholic education in the United Kingdom. It argues that Grace and Sullivan, when assessed together, represent a reinvigorated field of Catholic education and Catholic intellectual heritage.
