Apostle
In the Latter Day Saint movement, an apostle is a "special witness of the name of Jesus Christ who is sent to teach the principles of salvation to others." In many Latter Day Saint churches, an apostle is a priesthood office of high authority within the church hierarchy. As of March 31st, 2018, the Twelve Apostles of the LDS Church are: M. Russell Ballard, Jeffrey R. Holland, Dieter F. Uchtdorf, David A. Bednar, Quentin L. Cook, D. Todd Christofferson, Neil L. Anderson, Ronald A. Rasband, Gary E. Stevenson, Dale G. Renlund, Gerrit W. Gong, and Ulisses Soares. There are also members of the Quorum of the Seventy (referred to as “Seventies”). They typically work under the direction of the twelve apostles and are given similar responsibilities that build up the church. In many churches, apostles may be members of the Quorum of the Twelve Apostles of the church. In most Latter Day Saint churches, modern-day apostles are considered to have the same status and authority as the biblical apostles. In the Latter Day Saint tradition, apostles and prophets are believed to be the foundation of the church, with Jesus as the chief cornerstone. The Articles of Faith, written by Joseph Smith, mentions apostles: "We believe in the same organization that existed in the Primitive Church, namely, apostles, prophets, pastors, teachers, evangelists, and so forth."
Judaism's view of Jesus
Judaism's idea of the messiah differs substantially from the Christian idea of the Messiah. In Orthodox Judaism, the messiah's task is to bring in the Messianic Age, a one-time event, and a presumed messiah who is killed before completing the task (i.e. compelling all of Israel to walk in the way of Torah, repairing the breaches in observance, fighting the wars of God, building the Temple in its place, gathering in the dispersed exiles of Israel) is not the messiah. Maimonides states, 
Jews believe that the messiah will fulfill the messianic prophecies of the prophets Isaiah and Ezekiel. According to Isaiah, the messiah will be a paternal descendant of King David. He is expected to return the Jews to their homeland and rebuild the Temple, reign as King, and usher in an era of peace and understanding where "the knowledge of God" fills the earth, leading the nations to "end up recognizing the wrongs they did Israel". Ezekiel states the messiah will redeem the Jews.
