Work dossier · summary and historical context
The letter attributed to Pope John I (523–526) addresses the Acacian schism and asserts papal primacy. Dating to ca. 524, it survives in a single early medieval manuscript tradition, with the earliest witness a 9th-century copy from the Abbey of Saint-Denis. Included in the 6th-century Collectio Avellana and later cited in Gratian’s Decretum, the letter’s attribution to John I has been questioned on stylistic grounds, but no alternative author has gained acceptance. The present edition reproduces the 19th-century Migne text without collating the two known manuscript witnesses.
The letter is a key witness to early 6th-century papal claims to primacy and the resolution of the Acacian schism. Its inclusion in the Collectio Avellana and Gratian’s Decretum demonstrates its lasting influence on canon law and ecclesiology. The disputed authorship highlights the challenges of attributing early medieval papal letters.
The letter is set in the aftermath of the Acacian schism (484–519), a rift between the sees of Rome and Constantinople over the Henotikon of Emperor Zeno. Pope John I (523–526) reigned during the Ostrogothic rule of Italy under Theodoric the Great, who pressured the pope to negotiate with the Eastern emperor Justin I. The letter’s inclusion in the Collectio Avellana, a 6th-century canonical collection, indicates its early reception in ecclesiastical legal circles. Its citation in Gratian’s Decretum (C.24 q.1 c.1) as a patristic authority on papal primacy shows its later medieval importance. The text survives in a single manuscript tradition, with the earliest witness a 9th-century copy from Saint-Denis, suggesting limited circulation. The attribution to John I is disputed; Mommsen questioned it on stylistic grounds, but no consensus on an alternative author exists.
