This book has received more varied interpretations than probably any other book in the Bible.2Some writers believed it presents the reader with the "greatest hermeneutical challenge"in the Old Testament.3One excellent exegete called it "the most obscure book of the Old Testament."4
"Among the books of the Bible, the Song of Solomon is one of the smallest, most difficult, yet one of the most popular with both Jews and Christians. Over the centuries hundreds of books and commentaries have been written and unnumbered sermons preached on these 117 verses."5
Bible students have understood the Song of Solomon as an allegory, an extended type, a drama with either two or three main characters, or a collection of wedding songs. Others have thought it is a collection of pagan fertility cult liturgies or an anthology of songs extolling love, to name only the most common interpretations.6
Those who interpret the book allegorically--the majority of interpreters--believe that what the writer said is only a symbolic husk for a deeper spiritual meaning that the reader must discover. Jewish interpreters took this deeper revelation to be God's love for Israel. Christian scholars have frequently seen it as Christ's love for the church. However the text itself does not indicate that we should interpret this book differently than any other Bible book.7
Those who view it as an extended type believe the events recorded really took place, in contrast to the allegorical interpreters, but their primary significance lies in their illustrative value.8The basic teaching Christian interpreters see is Christ's love for the church. Yet again the text itself does not indicate that this book requires a different interpretation than the other books of the Bible.
A careful analysis of the text has convinced most scholars that the Song of Solomon was not a drama.9We really cannot break it down into acts and scenes in any presentable order. The action is too interwoven. There is also no evidence that the Hebrews had dramas of this type in Solomon's day.10
Some interpreters believe three main characters are in view, namely, Solomon, the Shulammite girl, and her shepherd lover.11However, what some scholars have attributed to the shepherd lover can just as easily refer to Solomon. It was not uncommon in ancient Near Eastern literature to refer to kings as shepherds since they served a pastoral function in relation to their people. Furthermore many of them did own many flocks (cf. 2:7).
Probably the Song of Solomon was a single love poem that the writer designed to deal primarily with the subject of human love and marriage. This was the viewpoint of many ancient Jewish rabbis.12It is also the conclusion most conservative commentators have come to who have sought to interpret this book in the same way they interpret other Bible books (i.e., literally, historically, and grammatically). It is also the conclusion of some liberal scholars who have analyzed the structure of the book.13Love is an important subject of special revelation, and human love in particular is a central feature of it as well (cf. Lev. 19:18; Matt. 22:36-39; John 13:34-35). Consequently it should not seem incredible that God gave us this book to help us understand this subject better.14
However, it seems clear that this book also has spiritual value, specifically to clarify divine-human love.
". . . it is widely acknowledged that the Bible is a book of faith and theology, and there is no place in the canon for atheological literature. . . .
"The literal approaches of Dillow, Glickman, and others are much more faithful to the intent of the book [than other approaches]. The limitations of these strictly literal approaches are the tendency to see sexuality as a more prominent feature of the Song than is justified by the text and the propensity to overreact to the absurdities of the allegorical method to the extent of missing justifiable [spiritual] analogy."15
Evidence of unity within the book argues against its being only a collection of poems that had general similarity to one another that the writer assembled into one song.16
