In the previous centuries, before the Vatican II, the Catholic Church officially use the Latin language especially in the Holy Mass. But there are two particular languages that was used in the Holy Mass that is not a latin, the Hebrew and Greek language. Hebrew is the original language of the Jews while the Greek is the first official language of the Catholic Church especially in the Holy Mass until it was changed into Latin and in 1570, become the language of the Holy Mass. But, two prayers remain in their original language, one of them is the Kyrie Eleison or “Lord Have Mercy”.
