The primacy of Lanfranc is one of the most memorable in our history. In the words of the parable put forth by Anselm in the next reign, the plough of the English Church was for seventeen years drawn by two oxen of equal strength. By ancient English custom the Archbishop of Canterbury was the King’s special counsellor, the special representative of his Church and people. Lanfranc cannot be charged with any direct oppression; yet in the hands of a stranger who had his spiritual conquest to make, the tribunitian office of former archbishops was lost in that of chief minister of the sovereign. In the first action of their joint rule, the interest of king and primate was the same. Lanfranc sought for a more distinct acknowledgement of the superiority of Canterbury over the rival metropolis of York. And this fell in with William’s schemes for the consolidation of the kingdom. The political motive is avowed. Northumberland, which had been so hard to subdue and which still lay open to Danish invaders or deliverers, was still dangerous. An independent Archbishop of York might consecrate a King of the Northumbrians, native or Danish, who might grow into a King of the English. The Northern metropolitan had unwillingly to admit the superiority, and something more, of the Southern. The caution of William and his ecclesiastical adviser reckoned it among possible chances that even Thomas of Bayeux might crown an invading Cnut or Harold in opposition to his native sovereign and benefactor.
