In 1232 Germanus II (1223-40), the Nicaean Patriarch of Constantinople, wrote to Pope Gregory IX and to the cardinals of the Roman Church requesting discussions on the reformation of peace between the Greek and Roman Churches. In response to this request the Pope sent two English Franciscans and two French Dominicans, at least one of them proficient in Greek, as his representatives to Nicaea. After their return the friars presented a detailed account of the mission to the Pope, which was copied into the Liber Censuum. The extant documentation of the mission allows us to examine the ideas of the Greeks and Latins about unity and schism in the Church. And it shows us that there was no prospect of a union of the Churches because each had a fundamentally different conception of the nature of ecclesiastical authority.
I should like to thank Dr Margaret Harvey and Professor Bernard Hamilton for their helpful comments upon earlier versions of this paper.
