Final answer:
All prayers, blessings, and priesthood ordinances in the LDS Church are done in the name of Jesus Christ to affirm faith in His divine authority and central role in salvation as part of the Holy Trinity.
Step-by-step explanation:
In Christian doctrine, specifically in the context of The Church of Jesus Christ of Latter-day Saints (LDS Church), all prayers, blessings, and priesthood ordinances are performed in the name of Jesus Christ because of the belief in the Holy Trinity, which includes God the Father, Jesus Christ, and the Holy Spirit. The 3rd paragraph of the section on Jesus Christ under the Godhead in the Doctrinal Mastery Core Document likely emphasizes Jesus Christ's central role in salvation and his divine authority. By invoking Christ's name, believers affirm their faith in His atonement and resurrection, which grants the authority to perform religious acts and access spiritual blessings. Therefore, the use of Jesus Christ's name is a declaration of faith and acknowledgment of His unique role within the Trinity and in the lives of the believers.
