The Messiah was supposed to deliver Israel from all oppressors and lead them into a new golden age. A rabbi from Galilee was not what they had in mind.
“Messiah”, “Anointed One” and “Christ” are some of the most common names used by Christians (“Christ followers”). We understand that Jesus (the) Christ is the anointed Son of God, Creator, and Lord of the Universe who came to earth once to suffer, die and be raised again to save us from our sins. One day He will come again to establish His perfect kingdom in the Universe. We see Him as a suffering servant, and a conquering hero. Given the full text of the Bible and our knowledge of what Jesus actually did, this is entirely reasonable. But the picture of the Messiah was far different to Jews in the first century.
Like America in 2011, Palestine in the first century AD was a diverse place, with Jews, Romans, Greeks, Persians, Arabs, Egyptians, Africans, and a host of others. Religions were aplenty, especially in Galilee, Samaria, and Perea, and political intrigue and violence was the norm. Many Jews longed for a return to the glorious days of King David, when Israel was the greatest power in the Near East. They also chafed under Roman domination, oppressive taxes, and the rule of an outsider, Herod. Spiritually, the Jews had been bereft of the prophetic voice of God for 400 years, and they hoped for another prophet to show the way.
