The following excerpt from an introduction to a recent volume shows the problematic nature of much of modern Latter-day Saint theological ecumenism:
To be forthcoming: I am a committed Latter-day Saint that dwells in Utah among my people. However, unlike many of my fellow Latter-day Saints, I have found compelling warrants within Mormon orthodoxy and orthopraxy to seek divine influence from rival traditions that potently refute various LDS beliefs and practices. (Charles Randell Paul, Converting the Saints: A Study of Religious Rivalry in America [Salt Lake City: Greg Kofford Books, 2018], xvii, emphasis added)
While many faiths contain important truths (e.g., baptismal regeneration is a doctrine preached by many faiths within the broad Christian spectrum, not just LDS), it is a grave error to claim that the Church acknowledges false doctrines that explicitly contradict the divine truth God has revealed to it. This shows the bizarre nature of “Mormon” theological ecumenism—false doctrines in other faiths can be elevated, not just being en par with divine truths, but supersedes such, too. Such only shows that the explicit teaching that The Church of Jesus Christ of Latter-day Saints is the only true Church (cf. D&C 1:30) is not taken seriously by church members these days.
