Working on the premise that wee can do our theological thinking using any book I have to add the caveat that whilst ALL and ANY book can challenge and shape my theology this does not make them 'theological'!
A brief conversation with someone who is studying theologically left me rather confused as they regarded the aforementioned tome as an authoritative theological voice on the Trinity. This for me was on a par with the 'darkness' offerings of Frank Peretti being regarded in the same light regarding Angelology.
Please don't think I'm knocking the books or the writers, I'm not. I can honestly say that having read them and enjoyed them to varying degrees my concern is that those who would consider themselves as students of that Queen of all sciences (Aquinus' term - not mine - Schleiermacher's too!) 'Theology' are in possession of such thinking.
More concern-making perhaps is the fact that the person on the other side of the conversation also thought that the 'Left behind' series was 'great theology' and a wonderful way to teach about the end times, after all (and I quote): 'It's easier to understand than revelation, isn't it?'
It certainly is, but it is not the authority some might confer upon it!
I am becoming increasing aware that I am moving towards a similar position as that occupied by that wonderfully visceral and curmudgeonly old goat, and namesake, Victor Meldrew when I say:
'I don't believe it - and I wish you wouldn't either!' Perhaps it's increasing old age taking effect - but hopefully it's an increasing desire to see people shape, share and apply stuff that sits well with the Bible.
Mind you, gut feelings apart, I am struggling to think that there are people who see angels sitting around the church building giving demons the bird and members of the Holy Trinity as characters like Mr McHenry, zipping around sans tricycle!
Stimulation and analogous writings are great because they give us different ways of looking at things. Fiction can, as I have said, shape, inform and bring about responses in us, but we need to keep a weather eye on how far we let them take us - after all, those who take the King's shilling and seek to serve Him in the ministry have a personal and a pastoral concern to be concerned over.
The Shack? It's a book - let's not lose sight of that?
