What does "Christ" mean?

³⁵Again the next day after John stood, and two of his disciples; ³⁶And looking upon Jesus as he walked, he saith, Behold the Lamb of God! ³⁷And the two disciples heard him speak, and they followed Jesus. ³⁸Then Jesus turned, and saw them following, and saith unto them, What seek ye? They said unto him, Rabbi, (which is to say, being interpreted, Master,) where dwellest thou? ³⁹He saith unto them, Come and see. They came and saw where he dwelt, and abode with him that day: for it was about the tenth hour. ⁴⁰One of the two which heard John speak, and followed him, was Andrew, Simon Peter’s brother. ⁴¹He first findeth his own brother Simon, and saith unto him, We have found the Messias, which is, being interpreted, the Christ. ⁴²And he brought him to Jesus. And when Jesus beheld him, he said, Thou art Simon the son of Jona: thou shalt be called Cephas, which is by interpretation, A stone.

³⁴Then Peter opened his mouth, and said, Of a truth I perceive that God is no respecter of persons: ³⁵But in every nation he that feareth him, and worketh righteousness, is accepted with him. ³⁶The word which God sent unto the children of Israel, preaching peace by Jesus Christ: (he is Lord of all:) ³⁷That word, I say, ye know, which was published throughout all Judæa, and began from Galilee, after the baptism which John preached; ³⁸How God anointed Jesus of Nazareth with the Holy Ghost and with power: who went about doing good, and healing all that were oppressed of the devil; for God was with him. ³⁹And we are witnesses of all things which he did both in the land of the Jews, and in Jerusalem; whom they slew and hanged on a tree: ⁴⁰Him God raised up the third day, and shewed him openly; ⁴¹Not to all the people, but unto witnesses chosen before of God, even to us, who did eat and drink with him after he rose from the dead. ⁴²And he commanded us to preach unto the people, and to testify that it is he which was ordained of God to be the Judge of quick and dead. ⁴³To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins.

¹³When Jesus came into the coasts of Caesarea Philippi, he asked his disciples, saying, Whom do men say that I the Son of man am? ¹⁴And they said, Some say that thou art John the Baptist: some, Elias; and others, Jeremias, or one of the prophets. ¹⁵He saith unto them, But whom say ye that I am? ¹⁶And Simon Peter answered and said, Thou art the Christ, the Son of the living God. ¹⁷And Jesus answered and said unto him, Blessed art thou, Simon Bar-jona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven.
