LDS often claim that Christ's church will have His name in the name of the church. Then they explain that the official name of the LDS Church is the Church of Jesus Christ of Latter-day Saints. But, the LDS Church has had at least five different names (D.H.C., Vol. III, p. 24). On April 6, 1830, it was originally called the "Church of Christ" (see D. & C. 20:1, D. & C., copyright page, or 1833 Book of Commandments). On May 3, 1834, the name was changed to the "Church of Latter Day Saints" (D.H.C., Vol. II, p. 63). Still later, on April 26, 1838, it was changed to the "Church of Jesus Christ of Latter-day Saints" as it is known today (D. & C. 115:3-4). If the church name is an earmark of being the true church, then the LDS Church could not have been true between 1834 and 1838, since neither Jesus nor Christ were in the official name of the LDS Church then!
Nowhere in the New Testament does either Christ or His disciples give an "official name" to the church. "The disciples were called Christians first in Antioch" (Acts 11:26). Note that it says that they were first called Christians about 34 A.D., not in 73 B.C. as Alma 46:15 says in the B. of M. But in Acts 24:5, they are called "Nazarenes." In Rom. 16:16, they are called "the church of Christ." In I Cor. 1:2, they are identified as "the Church of God." In Heb. 12:23, their name is "the church of the Firstborn." But, the New Testament church was never called "The Church of Jesus Christ!" Thus, the name by which the disciples were known was relatively unimportant, but the gospel they preached was very important (Gal. 1:8-9). That is what ought to be important to true believers in Christ today!
