Did "Christian" Exist in Justin's Greek, or Was It Added Later by Translators?
Person: Justin Martyr · 2nd century · Dialogue with Trypho 63–64 · Greek
What the ancient record says
Answered from the Greek. Ch.64: Χριστιανοὶ καλεῖσθαι (Christianoi kaleisthai, "to be called Christianoi").
Ch.63: Χριστιανοὶ γὰρ πάντες καλούμεθα ("for we are all called Christianoi"). So English "Christians" here translates an actual Greek identity term, not invented by a translator.
Proves the term Christianos/Christianoi existed in the textual tradition of Justin's works. Does not prove every follower of Yahusha preferred that identity, nor that the term originated with Justin.
Card necessary because our collection cannot criticize later terminology while inventing earlier terminology: if a source says Christianoi we say so; if Ioudaioi we say so; if an English translation uses a word not in the source language, we expose that too. The source language controls the claim.
Read it for yourself. Dialogue 63, 64.
Evidence strength: Directly proven from the surviving Greek.
