Perhaps you can see the dilemma of being a Christian within a secular culture. The works of imagination that reinforce our secular culture’s central religious vision are powerful and compelling movies and TV shows, popular songs and music, immersive computer and console games, widespread advertising imagery (moving and still), and malls, restaurants and whole cities built and shaped around a similar vision. Christians then find themselves being shaped by competing synoptic, moral and metaphorical visions. There is the secular imagination all around them in the workplace, the mall, and through every media portal they use; and there is the Christian imagination found only at church (hopefully), and in ageing books, poems and music.
What does the Christian imagination look like when it is fleshed out? We can imagine it as a spectrum, beginning with Scripture itself and working its way out from the explicitly biblical to what is only implicitly so.
The Bible. Scripture itself is the archetype of all Christian imagination. Its content and form are the our model for Christian imagination. Here God takes in all of human history (synoptical), explains the right and wrong way to respond to Him (moral), and communicates it in a metaphorical form: narratives, poetry, prophecy, apocalyptic, with plenty of imagery in the wisdom, epistolary and Law forms as well.
Quasi-biblical. Drawing from Scripture, believers through the ages have created works of imagination that distill, capture, or communicate something identical to or very close to Scripture. These include liturgies for worship, sermons, versified psalms or Scripture portions for singing, hymns based upon Scripture portions, sacred music (the setting of Scriptural texts to musical forms such as plainchant, masses, cantatas, oratorios), written prayers drawing deeply on the Psalms, and paintings, sculptures, illustrations of biblical scenes.
Christian extra-biblical. By extra-biblical we mean not “unbiblical”, but works of imagination that, though not paraphrases or depictions of Scripture itself, nevertheless capture Christian ideas, theology and experience. Hymns and spiritual songs, Christian verse (poetry with Christian themes or devotion), Christian epic poetry (such as Dante’s Inferno or Milton’s Paradise Lost), Christian allegory (such as The Pilgrim’s Progress or The Holy War), musical works themed after Christian theology (think “Jesu, Joy of Man’s Desiring”), devotional works (writings that seek to explicate Christian spirituality, such as The Ascent of Mount Carmel or The Pursuit of God), histories, biographies and autobiographies that explain the history and experience of Christians, various other Christian treatises, apologies and theologies, and a host of paintings, sculptures, carvings and other plastic arts that depict and illustrate Christian truth.
General semi-biblical. Many imaginative works are not explicitly Christian, but they carry the marks and imprint of a Christian culture. The attitude is birthed in, and consonant with, a Christian understanding of reality. These include many novels and much belletristic literature, poems, music, art, architecture, and for some, theatre and dance.
Taken together, what do we call this collection? The answer is simple and surprising: we call it Christian culture. The artefacts of a Christian imagination are what emerge from a Christian culture. Conversely, these artefacts come to define the contours of that culture, meaning that they are the symbolic embodiment of the culture: they give it its tone and identity. These works of imagination are both shaped by the people in the culture and shape those people who use and make them. This is how culture works: it cultivates around a cultus. The central religious vision of a culture leads its members to symbolise it in works of imagination, and the works of imagination reinforce and embody the central religious vision.
