Understand the Genre
First, let us, understand that there are different kinds of writing or literary styles, produced by different authors for different audience. They also invite different responses. For example, you would not read a recipe as you would a letter from a depressed friend. A court summons is no comic strip. A love letter demands a different reading to an encyclopaedia article.
As we read and study the Bible, we should recognise each type of genre. Parables, or parabolic passages, concentrated in the Gospels, are one of those genres.
The Bible also contains legal codes, such as those you can read in the Pentateuch, the first five books of the Old Testament. You will find poetry in Psalms and elsewhere. There are also prophecies, histories, hymns, letters and speeches in the Bible. There are allegories, metaphors, similes, epics, riddles and wise sayings. Scholars of the Bible call other sections 'didactic', 'apocalyptic' or 'eschatological'.
Yes, they all inspired by God. They are 'God-breathed' and 'useful for teaching, rebuking, correcting and training in righteousness, so that the man of God may be thoroughly equipped for every good work' (2 Timothy 3:16-17).
However, we need to see these literary genres - parables included - for what they are, in their contexts. We need to learn as much as we can about who wrote them, and why, and to whom . Legal codes and delicate poetry are different. Sweeping epics are not meant to be read like scientific texts. letters may whisper personal details about their writers even as they defy being used to nail down historical or prophetic dates.
Metaphors are not meant literally. Failure to understand the literary style can lead to misunderstanding and misinterpretation. How, then, should we look at Jesus' parables?
The Background to the Parables
Jesus' parables have been called 'heavenly stories with earthly meanings'. Yet there is more to them than that. Both the Hebrew word masal and the Greek parabole are broadly used of proverbs, allegories, riddles, illustrations and stories. They can refer to any striking speech formulated to stimulate thought.
Interpreter C.H. Dodd, in his 1935 classic Parables of the Kingdom, defined a parable as 'a metaphor or simile drawn from nature or common life, arresting the hearer by its vividness or strangeness, and leaving the mind in sufficient doubt about its precise application to tease it into active thought' (page 16).
