“Jesus sternly ordered them.
He commanded them
Not to tell anyone.”
ὁ δὲ ἐπιτιμήσας αὐτοῖς παρήγγειλεν μηδενὶ λέγειν τοῦτο,
Luke said that Jesus sternly ordered them (ὁ δὲ ἐπιτιμήσας αὐτοῖς) and commanded them (παρήγγειλεν) not to tell anyone (μηδενὶ λέγειν τοῦτο). This warning about the messianic secret can be found in all 3 synoptic gospels, Matthew, chapter 16:20, Mark, chapter 8:30, and here. However, this warning came right after Peter’s response in Mark and Luke, since they did not have the unique Matthew comment about the reward for Peter. Jesus, in some ironic way, did not want the people to know that he was the Messiah or the Christ. Thus, the name “Jesus Christ” did not take hold until after his death and resurrection. Mark simply said that Jesus sternly ordered, instructed, or charged his disciples that they were not to tell anyone that Jesus was the Christ or the Israelite Messiah. Matthew also said that Jesus sternly ordered, instructed, or charged his disciples so that they were not to tell anyone that he was the Christ or the Israelite Messiah, just like he had done earlier. This messianic secret was even stronger in Mark. Only the elite followers of Jesus knew that he was the Christ messiah, much like a gnostic special knowledge. How much knowledge do you have about Jesus?
