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."
Thomas the Apostle
The Nag Hammadi copy of the "Gospel of Thomas" begins: "These are the secret sayings that the living Jesus spoke and Didymos, Judas Thomas, recorded." Early Syrian traditions also relate the apostle's full name as Judas Thomas. Some have seen in the "Acts of Thomas" (written in east Syria in the early 3rd century, or perhaps as early as the first half of the 2nd century) an identification of Saint Thomas with the apostle Judas, Son of James, better known in English as Jude. However, the first sentence of the Acts follows the Gospels and the Acts of the Apostles in distinguishing the apostle Thomas and the apostle Judas son of James. Others, such as James Tabor, identify him as Judah, the brother of Jesus mentioned by Mark. In the Book of Thomas the Contender, part of the Nag Hammadi, he is alleged to be a twin to Jesus: "Now, since it has been said that you are my twin and true companion, examine yourself…"
