Justin’s Dialogue with Trypho

This post is part of an ongoing series on Paul and Pneuma, Justin and Judaism.

Although numerous writings have been attributed to Justin throughout the years, only three extant works are believed to be authentic: the First and Second Apologies[1] and the Dialogue with Trypho the Jew.[2] While some scholars have questioned if Justin could have written apologies and a dialogue, the general consensus holds his authorship of all three.[3] The earliest manuscript of the Dialogue is Codex Parisinus Graecus 450, dated to 11 September 1363 CE.[4] As for when the Dialogue was originally written no one can say for sure. Although internal evidence suggests that the dialogue was held over two days and at a time shortly after the bar Kokhba revolt (c. 135 CE).[5] Justin’s use of sources offers no further delimitations for the date of composition,[6] a further indication that the Dialogue could have been written any time between c.135 and 165 CE.

The Dialogue was addressed to an otherwise unknown Marcus Pompeius (Dial. 141) and Justin’s chief interlocutor was Trypho, a learned “Hebrew of the circumcision and a fugitive from the war that has just ended” (Dial. 1.3).[7] But apart from these obvious addressees, for whom was the Dialogue written? Scholars have argued for three audiences. First, the Dialogue was composed for a Jewish audience, an apology for a Christian reading of the Jewish scriptures.[8] Second, the Dialogue was composed for a pagan and primarily Gentile audience, seeking to prevent their conversion to Judaism.[9] Third, Justin wrote the Dialogue for Christians, either using a liturgical style or composing for an educational setting.[10] The theory which makes the most sense of internal and external evidence posits that the Dialogue was written for a Diaspora Jewish audience in the context of Christian missions and (somewhat quickly) found wider circulation among Christians opposed to Judaism.[11]

Justin employed a four-part structure in his Dialogue with the Jews, each of which spoke to his overarching theme of “how do we know what we know,” especially about the scriptures?[12] Chapters 1-9 describe Justin’s personal search for truth and his encounter with the Hebrew prophets. Chapters 10-30 explain the Christian interpretation of the Mosaic Law.[13] Chapters 31-108 discuss the person of Jesus, the divine messiah spoken of by the prophets. Finally, chapters 109-142 offers his thesis on the fact that Gentiles in Christ are the new spiritual Israel. Throughout this work Justin reveals his concern for properly Christocentric soteriology: since the old law has become obsolete and can no longer save, all must turn to the new law of Jesus the Christ.[14] Justin’s context in hand, this paper now considers Paul, particularly the facets of his theology on the Jewish-Gentile problem with which Justin interacted.


[1] The relationship of the First and Second Apology remains debated, with some suggesting both are part of a single work, see Parvis, 57. For a general introduction to the Apologies see Parvis, 56-9.

[6] Justin employs both the LXX and another Greek version in his citation of the Jewish scriptures. He also knows and uses Matthew, Romans, and Galatians. Scholars have posited his use of two other sources: a “testimony source” for Jewish writings and a “kerygma source” for Christian teaching. See? Dial. 121.1.

[11] This conclusion, of course, should raise awareness to the fact that Justin and Paul were likely writing to different ethnic audiences: Justin to Jews and Paul to Gentiles. Allert, 61.
