Scientific knowledge is revered in the Church of Jesus Christ of Latter-day Saints and a number of prominent apostles and Church leaders have been scientists. However the Church of Jesus Christ of Latter-day Saints also acknowledges revelation as a reliable source of knowledge and where science and the Latter-Day Saints religion may appear to conflict, Latter-day Saints work for a reconciliation in their understanding. The Church has few official doctrines that directly contradict scientific consensus and Latter-day Saints find ways to rationalise apparent contradictions. Use of pharmaceutical drugs by members is accepted so long as use is medicinal not recreational. There is no official Church teaching on how the Earth was made, members can be evolutionist or creationist; most are probably in between. A Church member can be a scientist with few conflicts. However, some earlier Church leaders have taught against evolution and some older Latter-Day Saint members will be against evolution. In short, official Church teaching is neutral about evolution; evolution is taught at Brigham Young University; there is no real conflict between science and religion; all the data are not yet known and eventually both will harmonise.
Church of Jesus Christ of Latter-day Saints claims to be a rational faith; for example, DNA work has called into question old Latter-Day Saint ideas that Native Americans are generally descendants of the twelve tribes of Israel, so Latter-Day Saint theologians look for ways that the Book of Mormon and DNA can both be true instead of rejecting scientific evidence out of hand. The historical claims of the Book of Mormon have been subjected to academic scrutiny, especially in archaeology and anthropology, which has led to some members pursuing alternative theories of Book of Mormon geography or seeking more naturalistic and less literal interpretations. Scholarly work at BYU tends to uphold and reaffirm Latter-Day Saints historical interpretations and the Book of Mormon as a work of literal ancient history, but Latter-day Saints scholars are constantly examining new ways to confront their past. At times, however, the Church has distanced itself from some historians and theologians who have provided alternative interpretations of Church history to what is in the Book of Mormon, these being seen by some as too ‘liberal’. Occasionally past leaders have warned against ‘alternate voices’ that would undermine key aspects of the faith, and issued reminders that intellectual and spiritual seeking should complement one another. The Church hierarchy to some extent tries to keep official sermons and writings, or writings that could be construed as official, in line with Church policy and teaching. For example, the Church requires pre-approval of members’ writings before publication if they are using archival materials of the Church. Some see this as attempting to control scholars’ depictions of Latter-Day Saint history. In general, however, and apparently in response to criticisms that this control has been too strong in the past, the Church is moving towards much greater openness in providing access to its archives and scholarly resources.
