Christ King

Christ the King is a title of Jesus Christ. It refers to the concept of the Kingdom of God where the Christ is imagined as seated at the Right Hand of God (as opposed to the secular title of King of the Jews mockingly given at the crucifixion).

The title "Christ the King" is also frequently used as a name for churches, schools, seminaries, hospitals and religious institutes.

The titles of "Christ" and "king" are not used together in the gospel, but "Christ" is in itself a royal title (i.e. "the anointed [king]"). In the Greek text, the Christ is explicitly identified as king (βασιλεύς) several times, so in Matthew 2:2 ("Where is the newborn king of the Jews?"). In John 18, Pilate refers to the implication that the Christ is a royal title by inquiring explicitly if Jesus claims to be the "king of the Jews" (βασιλεὺς τῶν Ἰουδαίων). Similarly, in John 1:49, a follower addresses Jesus as "the king of Israel" (ὁ βασιλεὺς τοῦ Ἰσραήλ).

Outside of the gospel, the First Epistle to Timothy (6:14–15) explicitly applies the phrase of "king of kings and lord of lords" (Βασιλεὺς βασιλέων καὶ κύριος κυρίων), taken from the Pentateuch (Deuteronomy 10:17) to Jesus Christ.

Pope Pius XI's first encyclical was Ubi arcano Dei consilio of December 1922. Writing in the aftermath of World War I, Pius noted that while there had been a cessation of hostilities, there was no true peace. He deplored the rise of class divisions and unbridled nationalism, and held that true peace can only be found under the Kingship of Christ as "Prince of Peace". "For Jesus Christ reigns over the minds of individuals by His teachings, in their hearts by His love, in each one's life by the living according to His law and the imitating of His example."
