I would disagree. The LDS Church does not promote fear or superstition in
it's teachings. As for modern science and knowledge, it's theories and
direction are always evolving. The LDS church embraces Science more so than
others. What was unknown becomes known. What was feared becomes understood, but
to proclaim that today's realm of knowledge has expanded to the point that
it can explain all things is irrational.
Although Mormon religion may not have a direct segue to ancient superstitious
religious rituals, the Mormon church has emulated and incorporated much of
man's fear and superstitions into their present day worship. This seems
like somewhat of a disconnect because of today's modern science and
knowledge, because of Mormonisms's claim to current day revelation.
Therefore one might rightly expect an up to date new account to explain
today's world rather than ancient traditions and superstitions
