A number of years ago, I read this blog post, which linked to this podcast episode about intertextuality between the New Testament and the Book of Mormon. The post and episode both focus on the work of Nick Frederick, a BYU professor who argues that:

If we’re comfortable saying that the New Testament is an antecedent text for the Book of Mormon, for the King James English 19th century Book of Mormon, then that opens up some wonderful avenues of inquiry. We can look at how those passages were understood in the 19th century and say, “Okay, is the Book of Mormon pushing back against something? Is the Book of Mormon affirming one of these ideas? What was the impact of these passages on early converts? How might this have changed through trajectories of 19th century theology?” Whereas if we just say, “No, no, no. It couldn’t be. There’s no way the New Testament was on the gold plates,” that just ends the conversation. If we see these as two different texts that are related through translation, then I think that helps us bridge this at least question of the New Testament in the Book of Mormon a little bit easier.
