Foreigner though he might be, it was the Primate's part to speak for the conquered race the words it could no longer utter. He was in fact the permanent leader (to borrow a modern phrase) of a Constitutional Opposition; and in addition to the older religious forces which he wielded he wielded a popular and democratic force which held the new King and the new baronage in check. It was he who received from the sovereign whom he crowned the solemn oath that he would rule not by his own will, but according to the customs, or as we should say now, the traditional constitution of the realm. It was his to call on the people to declare whether they chose him for their king, to receive the thundered "Ay, ay," of the crowd, to place the priestly unction on shoulder and breast, the royal crown on brow. To watch over the observance of the covenant of that solemn day, to raise obedience and order into religious duties, to uphold the custom and law of the realm against personal tyranny, to guard amid the darkness and brutality of the age those interests of religion, of morality, of intellectual life which as yet lay peacefully together beneath the wing of the Church,--this was the political office of the Primate in the new order which the Conquest created, and it was this office which expressed itself in the site of the house that fronted the King's house over Thames. From the days of Archbishop Anselm therefore to the days of Stephen Langton, Lambeth only fronted Westminster as the Archbishop fronted the King. Synod met over against Council; the clerical court of the one ruler rivalled in splendour, in actual influence, the baronial court of the other. For more than a century of our history the great powers which together were to make up the England of the future lay marshalled over against each other on either side the water.
