One of the more controversial aspects of Nephi’s vision of the tree of life is the great and abominable church or church of the devil. In his record, Nephi states that “there are save two churches only; the one is the church of the Lamb of God, and the other is the church of the devil” (1 Nephi 14:10). At times, Church leaders and members have associated “the church of the devil” with specific organizations, such as the Roman Catholic Church, while at others, they have tried to use it as a metaphor for any organization that promotes evil. In recent history, the leaders of the Church of Jesus Christ of Latter-day Saints have stressed the latter. Yet, there is also a Church of the Lamb of God that is spoken of by Nephi that is also worth discussing as an opposite counterpart of the church of the devil.
In his vision, Nephi reports seeing “the formation of a church which is most abominable above all other churches” that was founded by the devil and that “they have taken away from the gospel of the Lamb many parts which are plain and most precious; and also many covenants of the Lord have they taken away” (1 Nephi 13:5, 26). What this church of the devil was and how it participated in the Great Apostasy has been a matter of discussion over the years. Most famously, Elder Bruce R. McConkie taught that the Roman Catholic Church was this great and abominable church. This is what I was taught growing up in the post-McConkie era, to the point that I when a Catholic classmate at elementary school told me he was Catholic, I (unfortunately) responded: “Oh—that’s the great and abominable church, right?”, which left him very upset. The idea didn’t start with Elder McConkie, though. Many early Church members converted from Protestant backgrounds in the generally anti-Catholic environment of the early United States. At least as early as 1854, Elder Orson Pratt made the connection when wrote that the Roman Catholic Church was founded by “the Devil, through the medium of Apostates.” By 1906, Elder B. H. Roberts of the Seventy reported being asked “Is the Catholic church the church here referred to—the church of the devil?” while visiting outlying stakes of the Church. It is unfortunate and unfair to call the Roman Catholic Church the church of the devil or the great and abominable church—while there have been a lot of terrible things done in the name of that church, it has still been a force for good in the world and has played an important role in preserving the flame of Christianity throughout the centuries.
In recognition of the good that the Catholic Church does and our ongoing efforts to partner with them over moral issues, our Church has suggested alternative definitions of the great and abominable church. For example, in the “Come, Follow Me” curriculum this year, President Dallin H. Oaks is quoted as stating that the church in Nephi’s vision is “any philosophy or organization that opposes belief in God. And the ‘captivity’ into which this ‘church’ seeks to bring the saints will not be so much physical confinement as the captivity of false ideas.” Likewise, the Institute manual for the Book of Mormon cites a later explanation offered by Elder Bruce R. McConkie that calls the church of the devil all organizations that “are designed to take men on a course that leads away from God and his laws and thus from salvation in the kingdom of God.” That manual also cites a longer quote from Stephen E. Robinson that points out that “no single known historical church, denomination, or set of believers meets all the requirements for the great and abominable church.” The official stance of the Church today seems to be that the church of the devil includes any group that leads people away from God and to performing evil.
One of my favorite discussions about the churches from Nephi’s vision of the tree of life, however, comes from Elder B. H. Roberts. Elder Roberts was an influential general authority at the turn of the 20th century who was a prolific author on gospel topics and a well-respected orator. His writing and sermons had a strong impact on the Church, enough that they are part of our intellectual DNA today.
One topic on which this is true (and also relevant to the topic at hand) is the Great Apostasy. Roberts was among the first to publish a volume-length historical study of the Great Apostasy in the form of the 1893 Outlines of Ecclesiastical History. He continued to reiterate and develop his views in subsequent writings, including The Seventy’s Course in Theology and The Falling Away. As one scholar put it: “More than any Mormon scholar’s, Roberts’s ideas and approach effectively set the parameters and pattern for all subsequent discussions of apostasy.” That pattern, according to Eric R. Dursteler, was that there were innumerable “plain and precious truths” lost in the first Christian centuries, with the following Dark Age being the fullest expression of the effects of apostasy. The Renaissance, however, revived light and learning in the world, setting the stage for the Protestant Reformation, “which, in turn, acted as a prelude to the Restoration.” Other important authors working in the same era, like Elder James E. Talmage and Elder Joseph Fielding Smith, built on the work of B. H. Roberts to describe the Great Apostasy, and the writings of all three of these general authorities continue to shape our discussion of the topic today.
It should be noted before moving on that Elder Roberts rejected all Christian churches outside of the Church of Jesus Christ of Latter-day Saints as apostate and corrupted shadows of the true church of Jesus Christ. While he describes the failings of the Roman Catholic Church throughout the late classical and Medieval periods in detail, he states his opinion that the Protestant reformers “left more truth in the Catholic church than they brought out with them, or found in their speculations after leaving that church.” On another occasion, he stated that “so far as the Catholic church is concerned, I believe that there is just as much truth, nay, personally I believe that it has retained even more truth than other divisions of so-called Christendom.” The benefit of the Protestant Reformation was not that it restored truth or moved people closer to it, but that “it did overthrow the power of the Catholic Church in a great part of Western Europe, gave larger liberty to the people, and thus prepared the way for the greater work which followed it—the introduction of the Dispensation of the Fullness of Times.” Both Roman Catholic and Protestant churches were spoken of as being apostate organizations in Elder Roberts’s writings.
In 1906 at the spring general conference, Roberts focused a significant portion of his talk around the question “Is the Catholic church the church here referred to [in 1 Nephi 14]—the church of the devil?” Given how he focused on the failings of the Medieval Catholic Church in his book on the Great Apostasy, one might wonder if he would have responded that the church of the devil was indeed the Catholic Church. He did not, however, feel like that was a good answer. His answer was that: “I would not like to take that position, because it would leave me with a lot of churches on my hands that I might not then be able to classify.” He went on to say: “I would not like … to designate the Catholic church as the church of the devil. Neither would I like to designate any one or all” of the various faiths and religions found around the world. Instead, he felt that Nephi “has in mind no particular church, no particular division of Christendom, but he has in mind … the whole empire of Satan; and perhaps the thought of the passage would be more neatly expressed if we use the term ‘the kingdom of evil’ as constituting the church of the devil.” This church of the devil, then, is summed up by Elder Roberts as “evil … untruth … [and] all combinations of wicked men.” 
While Elder Roberts was known to emphasize the idea that all other faiths and religions are apostate, he still acknowledged that they had portions of the truth and righteous individuals. In his 1906 general conference address, he stated that “they have retained fragments of Christian truth … and it would be poor policy for us to contend against them without discrimination.” Elsewhere, he wrote that, “just as when the sun goes down, there still remains light in the sky— so, too, notwithstanding this apostasy from the Church, there still were left fragments of truth among the children of men. … The light of truth burned in the bosom of good men.” This understanding of other churches informed how he interpreted the counterpart of the church of the devil, the “Church of the Lamb of God” that Nephi spoke of in 1 Nephi 14.
Elder Roberts defined the church of the Lamb of God as being the opposite of the church of the devil. He said: “All that makes for untruth, for unrighteousness constitutes the kingdom of evil—the church of the devil. All that makes for truth, for righteousness, is of God; it constitutes the kingdom of righteousness—the empire of Jehovah; and, in a certain sense at least, constitutes the Church of Christ.” As such, the Church of the Lamb of God is larger than just the membership of the Church of Jesus Christ of Latter-day Saints and includes all who “are seeking to know God and to keep His commandments.” With this understanding in mind, Elder Roberts encouraged his audience to “seek to enlarge this kingdom of righteousness both by recognizing such truths as it possesses and seeking the friendship and co-operation of the righteous men and women who constitute its membership.” B. H. Roberts felt that God-fearing individuals throughout the world were a part of the Church of the Lamb of God, not only members of our church.
There are parallels to Elder Roberts’s understanding of the Church of the Lamb of God in the writings of other Latter-day Saints. Terryl L. Givens, for example, has drawn on the writings of Protestant authors who spoke of the true church of Christ fleeing into the wilderness like the woman in Revelation 12 and rendered “invisible, protected, nourished, and preserved.” This invisible church continued to exist throughout the apostasy “where righteous individuals, their spiritual gifts, and godly principles and practices persisted.” In his writings, Givens points to people spoken of in a revelation to Joseph Smith as “those which I have reserved unto myself, holy men that ye know not of” (D&C 49:8) as members of this invisible church. Givens, in a manner similar to Elder Roberts, suggests that this idea of an invisible Church of righteous individuals is an important part of “reconsidering the meaning of … the Church of the Lamb of God.”
Thus, when reading 1 Nephi 13-14, both churches spoken of can be broadened out considerably from narrow interpretations of specific organizations. Elder B. H. Roberts understood that when Nephi writes that “there are save two churches only; the one is the church of the Lamb of God, and the other is the church of the devil” (1 Nephi 14:10), one cannot assign only one specific organization to each of those churches, since it would “would leave me with a lot of churches on my hands that I might not then be able to classify.” Instead of fighting specific organized religions, he felt that, “the servants of God have a right to contend against that which is evil, let it appear where it will, in Catholic or in Protestant Christendom, among the philosophical societies of deists and atheists, and even within the Church of Christ, if, unhappily, it should make its appearance there” and to embrace those who “are seeking to know God and to keep His commandments” as members of the Church of the Lamb of God.
