Christ is one of the names of the Lord. It derives from Greek, and means "the anointed one," a King or Messiah. Christ as King brings to mind the infinite Divine truth, while Jesus as savior brings to mind the infinite Divine mercy and love. Together they mean both of these qualities conjoined and so bring to mind the very essence of the Lord.

3006. These are the things that angels perceive when the names Jesus Christ are used, and the things that are meant by its being said that in no other name is there salvation, and by what the Lord stated so many times concerning His name, as in John,

Whatever you ask in My name, I will do. John 14:13-14.

In the same gospel,

These things have been written that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in His name. John 20:31.

And elsewhere. 'His name' means everything in its entirety by which the Lord is worshipped, and so the essential nature of all worship and doctrine, see 2724. Here therefore the good of love and charity is meant when joined to the truth of faith, which constitutes the fabric of doctrine and worship in their entirety.
