"Messiah"

I knew that the oratorio "Messiah" is always sang in the Christmas season, and Japanese pronounce the oratorio in the same way as English.
However, when we indicate the word Messiah for Christ, we pronounce it differently. We pronounce it as "me-si-ah," and also write both words differently.

Therefore, I didn't notice that the oratorio Messiah directly meant to be Jesus Christ. I learned it when I first read the booklet at the concert last year.
