William the Conqueror, the most potent, the most haughty, and the most vigorous prince in Europe, was not, amidst all his splendid successes, secure from the attacks of this enterprising pontiff. Gregory wrote him a letter, requiring him to fulfil his promise in doing homage for the kingdom of England to the see of Rome, and to send him over that tribute, which all his predecessors had been accustomed to pay to the vicar of Christ. By the tribute he meant Peter's pence; which, though at first a charitable donation of the Saxon princes, was interpreted, according to the usual practice of the Romish court, to be a badge of subjection acknowledged by the kingdom. William replied, that the money should be remitted as usual; but that neither had he promised to do homage to Rome, nor was it in the least his purpose to impose that servitude on his state [g]. And the better to show Gregory his independence, he ventured, notwithstanding the frequent complaints of the pope, to refuse to the English bishops the liberty of attending a general council which that pontiff had summoned against his enemies.

But though the king displayed this vigour in supporting the royal dignity, he was infected with the general superstition of the age, and he did not perceive the ambitious scope of those institutions, which, under colour of strictness in religion, were introduced or promoted by the court of Rome. Gregory, while he was throwing all Europe into combustion by his violence and impostures, affected an anxious care for the purity of manners; and even the chaste pleasures of the marriage-bed were inconsistent, in his opinion, with the sanctity of the sacerdotal character. He had issued a decree prohibiting the marriage of priests, excommunicating all clergymen who retained their wives, declaring such unlawful commerce to be fornication, and rendering it criminal in the laity to attend divine worship, when such profane priests officiated at the altar [h]. This point was a great object in the politics of the Roman pontiffs; and it cost them infinitely more pains to establish it, than the propagation of any speculative absurdity which they had ever attempted to introduce. Many synods were summoned in different parts of Europe before it was finally settled; and it was there constantly remarked, that the younger clergymen complied cheerfully with the pope's decrees in this particular, and that the chief reluctance appeared in those who were more advanced in years: an event so little consonant to men's natural expectations, that it could not fail to be glossed on, even in that blind and superstitious age. William allowed the pope's legate to assemble, in his absence, a synod at Winchester, in order to establish the celibacy of the clergy; but the church of England could not yet be carried the whole length expected. The synod was content with decreeing, that the bishops should not thenceforth ordain any priests or deacons without exacting from them a promise of celibacy; but they enacted, that none, except those who belonged to collegiate or cathedral churches, should be obliged to separate from their wives.
