Biblical Authority in the Writing of Pope Innocent IV (1243-54)
When discussing the thirteenth-century concept of Christian unity, Jack Watt asserted, ‘Too little is as yet known of the interaction of theological and canonical thought to be able to say with precision just what the canonists contributed to this development among more abstract thinkers and what they received from it.’ Thirty-five years on this comment largely remains true for our knowledge of the inter-relation of theology and canon law in the thirteenth century. Little attention has been paid to the impact of theology on canon law, and even less to canon law on theological thinking. G.R. Evans claimed, ‘Canon law glosses tend to be conservative and less theologically sophisticated than contemporary theological work.’ That comment could be seen as an explanation for how little attention has been paid to the theological content of canonical writing. However, canon law glosses were written principally to investigate law. The area of ‘sophistication’ was different. Yet, this is not to say that there was no interest in theological questions and their possible solutions on the part of the canonists. All canon lawyers had a theological education, and they cited biblical references to support their arguments extensively. This paper aims to show that the use and understanding of contemporary medieval theology had an important impact on the writing of thirteenth-century canon lawyers, which should not be readily overlooked by modern scholars.
