He did not answer.
The high priest
The Messiah Christ?
The Son of the Blessed One?’”
ὁ δὲ ἐσιώπα καὶ οὐκ ἀπεκρίνατο οὐδέν. πάλιν ὁ ἀρχιερεὺς ἐπηρώτα αὐτὸν καὶ λέγει αὐτῷ Σὺ εἶ ὁ Χριστὸς ὁ Υἱὸς τοῦ Εὐλογητοῦ;
This is almost word for word in Matthew, chapter 26:63. In Luke, chapter 22:66-70, there was something similar. However, there was nothing like this in John, chapter 18:19, where there was a discussion of the high priest with Jesus, but more about his teachings. Mark said that Jesus was originally silent (ὁ δὲ ἐσιώπα). He did not answer the high priest (καὶ οὐκ ἀπεκρίνατο οὐδέν). Then the high priest again asked Jesus directly (πάλιν ὁ ἀρχιερεὺς ἐπηρώτα αὐτὸν). Was he the Messiah Christ (καὶ λέγει αὐτῷ Σὺ εἶ ὁ Χριστὸς)? Was he the Son of the Blessed One (ὁ Υἱὸς τοῦ Εὐλογητοῦ)? Matthew had said that the high priest Caiaphas was going to put him under oath according to the living God. Jesus was to tell everyone there whether he was the Christ, the Messiah, the Son of God. Luke indicated that they asked Jesus whether he was the Messiah Christ or the Son of God. Thus, this was a clear question about the divine claims of Jesus, particularly his messianic Christ role and his relationship to God the Father.
