Here's what I found in my study:
"Jesus Christ" (His name and title) is used in the introductions of Matthew, Mark, and John's accounts (Mt 1:1, 1:18, Mk 1:1, Jn 1:17). Jesus refers to himself as "Jesus Christ" in John 17:3.
The words "King," "Christ," or "Messiah" appear in the following places in the gospels:
-Jesus' family tree (Mt 1:1, 1:6, 1:16-17)
-John the Baptist is not the Christ (Lk 3:15, Jn 1:20, 1:25, 3:28)
-The one born King of the Jews (Mt 1:18, 2:2-4, Lk 2:11, 2:26)
-The people want to make Jesus king by force (Jn 6:15)
-Testimony that Jesus is the Christ (Mt 11:2, Jn 1:41, 1:49, 4:29, 4:42, 11:27; Lk 4:41; Mt 16:16, Mk 8:29, Lk 9:20, Jn 6:69; Jn 9:22)
-The people wonder if Jesus is the Christ (Jn 7:26-27, 7:31, 7:41-42, 12:34)
-Hosanna to the King (Mt 21:9, Mk 11:10, Lk 19:38, Jn 12:13; Mt 21:5, Jn 12:15)
-Jesus asks them: Whose son is the Christ? (Mt 22:42, Mk 12:35, Lk 20:41)
-Warning about false Christs (Mt 24:5, 24:23, Mk 13:21)
-Jesus speaks of the Christ in various contexts (Mt 23:8-10, Mk 9:41)
-Jesus calls himself "Christ" in prayer (Jn 17:3)
-Jews ask: Are you the Christ? (Mt 26:63, Mk 14:61, Lk 22:67, Jn 10:24)
-Gentiles ask: Are you the King of the Jews? (Mt 27:11, Mk 15:2, Lk 23:3, Jn 18:33)
-The nations rage (Mt 27:17-22, Mk 15:9-12, Lk 23:2, Jn 18:37-39, Jn 19:12-15, 19:21)
-Jews mock: Prophesy to us, Christ! (Mt 26:68)
-Gentiles mock: Hail, King of the Jews! (Mt 27:29, Mk 15:18, Jn 19:3)
-People mock: If you are the King of the Jews, save yourself! (Mt 27:42, Mk 15:32, Lk 23:35-39)
-The declaration on Jesus' cross: This is Jesus the King of the Jews (Mt 27:37, Mk 15:26, Lk 23:38, Jn 19:19)
-It was necessary for the Christ to suffer (Lk 24:26, 24:46)
-That you may know (Jn 20:31)
