Jesus is called the Christ (a Greek word) or the Messiah (an Aramaic word). Both words mean “the anointed.” He is the one anointed of the Father to be the Father’s personal representative in all things pertaining to the salvation of mankind.(LDS Scripture Study Helps)
Anointed One“God anointed Jesus of Nazareth with the Holy Ghost and with power” (Acts 10:38). Jesus was the Anointed One. Because of this fact, He was accorded two specific titles. One was the Messiah, which in Hebrew means “the anointed.” The other was the Christ, which comes from the Greek word that also means “the anointed.” Thus, “Jesus is spoken of as the Christ and the Messiah, which means he is the one anointed of the Father to be his personal representative in all things pertaining to the salvation of mankind” (Bible Dictionary, “Anointed One,” 609). Scriptures declare that Christ is the only name under heaven whereby salvation comes (see 2 Ne. 25:20). So one may add either of these titles to signify adoration for Jesus: the Christ or the Messiah, both signifying an anointing by God for that supernal responsibility.Jesus the Christ: Our Master and More, Russell M.
