While exegetical and theological treatises often provide the most comprehensive sources for our understanding of the interpretive methods of patristic authors, personal letters also provide a unique perspective. Such is the case with the present letter, attributed to Severus of Antioch and addressed to the deaconess Anastasia. Marius Chaîne publishes here for the first time the Coptic text of the letter and provides a French translation. The letter is presumably a response to a question posed by Anastasia on the interpretation of Matthew 23:35 and thus contains an exegetical exposition of that verse. In his introduction to the text, Chaîne discusses the authenticity of the attribution to Severus, the exegetical method, and the parallel exegetical accounts of the passage in question.
