Have you ever heard something and wondered, “Is that Church doctrine?” For example, suppose you were in a Church class studying the passage where God teaches Moses there are “worlds without number . . . and by the Son I created them, which is mine Only Begotten” (Moses 1:33). Someone asks, “If Jesus created multiple worlds, did Jesus’s infinite Atonement redeem God’s children on other earths?” What would you say? Is that true? Is it a sanctioned Church teaching? How would you know?
