Luke does not criticize prior Gospel narratives; he adds to them with more data

Unlike Josephus who opens some works by attacking prior accounts as inadequate, Luke does not criticize the other narratives. He affirms that prior compilers also based their work on eyewitness testimony. Luke writes his own orderly account because he has additional data from having closely followed these matters for a long time — a desire for a more complete record, not a correction of errors.
