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."
Judas Iscariot
The name "Judas" (Ὶούδας) is a Greek rendering of the Hebrew name Judah (יהודה, Yhûdâh, Hebrew for "God is praised"), which was an extremely common name for Jewish men during the first century AD, due to the renowned hero Judas Maccabeus. Consequently, numerous other figures with this name are mentioned throughout the New Testament. In the Gospel of Mark , the earliest of all the gospels, which was written in the mid 60s or early 70s AD, Judas Iscariot is the only apostle named "Judas". follows this portrayal. The Gospel of Luke , however, replaces the apostle whom Mark and Matthew call "Thaddeus" with "Judas son of James". Peter Stanford suggests that this renaming may represent an effort by the author of the Gospel of Luke to create a "good Judas" in contrast to the betrayer Judas Iscariot.
