Sometimes we are told that committed and "Christian" scholarship must be partial and biased because, well, to paraphrase Ms Mandy Rice Davies, we would say that, wouldn't we. Some years ago, in her inaugural lecture as a Professor in this University, Sarah Foot put this notion down.
She was not keen on the idea that, in order to be 'academic', the 'profession' in a modern university of a subject like ecclesiastical history has to be left to those who have a reductionist view, and who see the subject from a hostile and secularising standpoint in which Faith simply has to be considered a facade for more mundane and untheological historical processes. It is the duty of the ecclesiastical historian to restore 'their present' to earlier communities by taking them seriously. While the student does not have to be a believer, (s)he should have an empathetic (my word) understanding of the faithed humans (s)he describes.
I find it a remarkable example of diabolical skill, this idea that only those hostile to Christianity really count as impartial; as if Christians must be disqualified for having a biasing agenda but atheists are dispassionate students of their subject. I recall the passage in The Pilgrim's Regress in which C S Lewis portrays the minions of the Zeitgeist indoctrinating their prisoners:
What is the proper answer to an argument proving the existence of the Landlord [God]?
You say that because you are a Steward [priest].
Good boy ... what is the answer to an argument that two and two make four?
You say that because you are a mathematician ...
Professor Jonathan Riley-Smith of the Daughter University spent some decades restoring a genuine theological conviction to the Crusaders. And I remember particularly the words of M Schneiders in 1996, discussing early Irish liturgy: for a proper understanding of the past an affinity with the material is useful, at least if one wishes to go beyond the recovery of mere facts, if one tries to understand the people who used these texts, who celebrated Mass with these ancient prayers.
But 'useful' is too timorous a word; and Dom Gregory 'Patrimony' Dix put it so much more memorably ... well, he would, wouldn't he? ... when, writing about the Canon Romanus, he said: This very morning I 'did this' with a set of texts which has not changed by more than a few syllables since Augustine used those very words at Canterbury on the Third Sunday of Easter in the summer after he landed. Yet 'this' can still take hold of a man's life and work with it.
