The CES Letter lists concerns about the restoration of priesthood authority. Although this section in the CES Letter has several subsections (e.g., "Before 1832," "David Whitmer," "Backdating," etc.), the repeated concern is whether or not Joseph Smith fabricated receiving the priesthood by angels. Resources addressing this concern include the following:

• "The CES Letter Rebuttal, Part 43: Priesthood Restoration Questions, Section A"
• "The CES Letter Rebuttal, Part 44: Priesthood Restoration Questions, Section B"
• Joseph Smith and the priesthood
• Why and how revelations were modified in the Doctrine and Covenants
