Robert James Matthews (12 September 1926 – 30 August 2009) was a Latter-day Saint religious educator and scholar, teaching in the departments of Ancient Scripture and Religious Education at Brigham Young University (BYU) in Provo, Utah.
Beginning with personal contacts early in his career, Matthews was instrumental in conciliating relations between religious scholars affiliated with the Church of Jesus Christ of Latter-day Saints (LDS Church) and the Reorganized Church of Jesus Christ of Latter Day Saints (now called the Community of Christ), which had separated in a schism in the 1840s. The two religious communities and their scholars had long been at odds over access to and interpretation of important early texts of the Latter Day Saint movement. Matthews was particularly influential when in 1969 and 1970, scholars affiliated with the RLDS were invited to meetings of the Mormon History Association. The new scholars were welcomed, and some were chosen as officers in the organization in later years. Matthews is also noted for his promotion of the concept that the currently-available text of the Joseph Smith Translation of the Bible is reliable and authentic.
