21. The Book of Psalms is full of prophecies in regard to Christ, giving details concerning His birth, His life, His doctrines, His sufferings, His death, His resurrection and His everlasting Kingdom. After Moses, Prophets were sent from time to time, to keep constantly before the minds of the Chosen People the worship of the one God, the observance of the Mosaic Law, the expectation of the Messias, the time, place, and manner of His coming, etc.
It will be noticed that the words "Messias" and "Christ" are used promiscuously for each other; both mean the "Anointed"; of this term " Messias" is the Hebrew, "Christ" the Greek equivalent. Thus, during the Passion of Christ, when the High-Priest adjured Jesus to tell if He were "the Christ the Son of God," he evidently asked whether he were the expected "Messias" (Matt. XXVI, 63); and St. John writes: "The Messias, which is, being interpreted, the Christ" (I, 41).
