The Song of Solomon is the only book in the standard works that is considered uninspired (see Bible Dictionary, “Song of Solomon”). When speaking to a group of seminary and institute teachers, Elder Bruce R. McConkie of the Quorum of the Twelve Apostles commented on each of the books in the Old Testament. When he came to this book he said, “The Song of Solomon is biblical trash—it is not inspired writing” (“The Bible, a Sealed Book,” in Teaching Seminary: Preservice Readings [Church Educational System manual, 2004], 127).
“[The Song of Solomon is] sometimes called Canticles (as in Latin) or Song of Songs (as in Hebrew). … Both Jews and Christians have at times been reluctant to accept it into the canon of scripture because of its romantic content but have permitted it on the basis of its being an allegory of God’s love for Israel and of the Church” (Bible Dictionary, “Song of Solomon”).
