Because the text mentions Justin Martyr's ''[[First Apology of Justin Martyr|First Apology]]'', which was written sometime between AD 150-155 CE, ''Dialogue with Trypho'' must have been written after it. The date of authorship has been suggested to have been written anywhere between 155-167,<ref>{{cite book|last1=Allert|first1=Craig D.|title=Revelation, Truth, Canon and Interpretation: Studies in Justin Martyr's Dialogue with Trypho|date=2002|publisher=Brill|page=34|quote=If ''1 Apology'' lies between 151–154, and because the ''Dialogue'' mentions the ''Apology'' it is certain that the ''Dialogue'' was composed after that date.
