Luke mentions other accounts of Jesus.
Gospel of Luke, Codex Sinaiticus (ca. 325), Luke 1:1-3
επειδηπερ πολλοι επεχειρηϲαν ανα ταξαϲθαι διηγηϲιν περι των πεπλη ροφορημενων εν ημιν πραγματω καθωϲ παρεδοϲαν ημιν οι απ αρχηϲ αυ τοπται και ϋπηρε ται γενομενοι του λογου εδοξε καμοι παρηκολουθηκοτι ανωθεν παϲιν α>κρειβωϲ καθεξηϲ ϲοι γραψαι κρατιϲτε. Translation: 1:1 Since many have undertaken to draw up a narrative of the matters that have been fully accomplished among us,
2 as those, who, from the beginning became eyewitnesses and ministers of the word, delivered them to us,
3 it seemed good to me also, after having accurately traced all things from the first, to write them in order for thee, most noble Theophilus.
