Why do Christians call Jesus "the Christ"?

A is the correct answer

Explanation:

Because if you look up Messiah it originates from the Greek language

The concept of the Christ in Christianity originated from the concept of the messiah in Judaism. Christians believe that Jesus is the messiah foretold in the Hebrew Bible and the Christian Old Testament. Although the conceptions of the messiah in each religion are similar, for the most part they are distinct from one another due to the split of early Christianity and Judaism in the 1st century.

Christ, used by Christians as both a name and a title, is synonymous with Jesus.
