What was the true and natural character of Thomas Becket, what were really the ideals on which he would have chosen to form his life if he had been entirely free to shape it as he would, is a puzzle which this is not the place to try to solve. Nor can we discuss here the critical questions, still unsettled, which the sources of our knowledge present. Fortunately no question affects seriously the train of events, and, in regard to the character of the archbishop, we may say with some confidence that, whatever he might have chosen for himself, he threw himself with all the ardour of a great nature into whatever work he was called upon to do. As chancellor, Thomas's household had been a centre of luxurious court life. As archbishop his household was not less lavishly supplied, nor less attractive; but its elegance was of a more sober cast, and for himself Thomas became an ascetic, as he had been a courtier, and practised in secret, according to his biographers, the austerities and good works which became the future saint.
Six months after the consecration of the new archbishop, King Henry crossed from Normandy to England, at the end of January, 1163, but before he did so word had come to him from Becket which was like a declaration of principles. Henry had hoped to have him at the same time primate of the Church and his own chancellor. Not merely would this add a distinction to his court, but we may believe that the king would regard it as a part of the co-operation between Church and State in the reforms he had in mind. To Thomas the retention of his old office would probably mean a pledge not to oppose the royal will in the plans which he no doubt foresaw. It would also interfere seriously with the new manner of life which he proposed for himself, and he firmly declined to continue in the old office. In other ways, unimportant as yet, the policy of the primate as it developed was coming into collision with the king's interests, in his determined pushing of the rights of his Church to every piece of land to which it could lay any claim, in some cases directly against the king, and in his refusal to allow clerks in the service of the State to hold preferments in the Church, of which he had himself been guilty; but all these things were still rather signs of what might be expected than important in themselves. There was for several months no breach between the king and the archbishop.
For some time after his return to England Henry was occupied, as he had been of late on the continent, with minor details of government of no permanent importance. The treaty of alliance with Count Dietrich of Flanders was renewed. Gilbert Foliot was translated to the important bishopric of London. A campaign in South Wales brought the prince of that country to terms, and was followed by homage from him and other Welsh princes rendered at a great council held at Woodstock during the first week of July, 1163. It was at this meeting that the king first met with open and decided opposition from the archbishop, though this was still in regard to a special point and not to a general line of policy. The revenue of the state which had been left by the last reign in a disordered condition was still the subject of much concern and careful planning. Recently, as our evidence leads us to believe, the king had given up the Danegeld as a tax which had declined in value until it was no longer worth collecting. At Woodstock he made a proposition to the council for an increase in the revenue without an increase in the taxation. It was that the so-called "sheriffs aid," a tax said to be of two shillings on the hide paid to the sheriffs by their counties as a compensation for their services, should be for the future paid into the royal treasury for the use of the crown. That this demand was in the direction of advance and reform can hardly be questioned, especially if, as is at least possible, it was based on the declining importance of the sheriffs as purely local officers, and their increasing responsibilities as royal officers on account of the growing importance of the king's courts and particularly of the itinerant justice courts. So decided a change, however, in the traditional way of doing business could only be made with consent asked and obtained. There is no evidence that opposition came from any one except Becket. He flatly refused to consent to any such change, as he had a right to do so far as his own lands were concerned, and declared that this tax should never be paid from them to the public treasury. The motive of his opposition does not appear and is not easy to guess. He stood on the historical purpose of the tax and refused to consider any other use to which it might be put. Henry was angry, but apparently he had to give up his plan. At any rate unmistakable notice had been served on him that his plans for reform were likely to meet with the obstinate opposition of his former chancellor.
This first quarrel was the immediate prelude to another concerning a far more important matter and of far more lasting consequences. Administration and jurisdiction, revenue and justice, were so closely connected in the medieval state that any attempt to increase the revenue, or to improve and centralize the administrative machinery, raised at once the question of changes in the judicial system. But Henry II was not interested in getting a larger income merely, or a closer centralization. His whole reign goes to show that he had a high conception of the duty of the king to make justice prevail and to repress disorder and crime. But this was a duty which he could not begin to carry out without at once encountering the recognized rights and still wider claims of the Church. Starting from the words of the apostle against going to law before unbelievers, growing at first as a process of voluntary arbitration within the Church, adding a criminal side with the growth of disciplinary powers over clergy and members, and greatly stimulated and widened by the legislation of the early Christian emperors, a body of law and a judicial organization had been developed by the Church which rivalled that of the State in its own field and surpassed it in scientific form and content. In the hundred years since William the Conqueror landed in England this system had been greatly perfected. The revival of the Roman law in the schools of Italy had furnished both model and material, but more important still the triumph of the Cluniac reformation, of the ideas of centralization and empire, had given an immense stimulus to this growth, and led to clearer conceptions than ever before of what to do and how to do it. When the state tardily awoke to the same consciousness of opportunity and method, it found a large part of what should have been its own work in the hands of a rival power.
In no state in Christendom had the line between these conflicting jurisdictions been clearly drawn. In England no attempt had as yet been made to draw it; the only legislation had been in the other direction. The edict of William I, separating the ecclesiastical courts from the temporal, and giving them exclusive jurisdiction in spiritual causes, must be regarded as a beneficial regulation as things then were. The same thing can hardly be said of the clause in Stephen's charter to the Church by which he granted it jurisdiction over all the clergy; yet under this clause the Church had in fifteen years drawn into its hands, as nearly as we can judge, more business that should naturally belong to the state than in the three preceding reigns. This rapid attainment of what Anselm could only have wished for, this enlarged jurisdiction of the Church, stood directly in the way of the plans of the young king as he took up the work of restoring the government of his grandfather. He had found out this fact before the death of Archbishop Theobald and had taken some steps to bring the question to an issue at that time, but he had been obliged to cross to France and had not since been able to go on with the matter. Now the refusal of Archbishop Thomas to grant his request about the sheriff's aid probably did not make him any less ready to push what he believed to be the clear rights of the state against the usurpations of the clergy.
As the state assumed more and more the condition of settled order under the new king, and the courts were able to enforce the laws everywhere, the failures of justice which resulted from the separate position of the clergy attracted more attention. The king was told that there had been during his reign more than a hundred murders by clerks and great numbers of other crimes, for none of which had it been possible to inflict the ordinary penalties. Special cases began to be brought to his attention. The most important of these was the case of Philip of Broi, a man of some family and a canon of Bedford, who, accused of the murder of a knight, had cleared himself by oath in the bishop's court. Afterwards the king's justice in Bedford summoned him to appear in his court and answer to the same charge, but he refused with insulting language which the justice at once repeated to the king as a contempt of the royal authority. Henry was very angry and swore "by the eyes of God," his favourite oath, that an insult to his minister was an insult to himself and that the canon must answer for it in his court. "Not so," said the archbishop, "for laymen cannot be judges of the clergy. If the king complains of any injury, let him come or send to Canterbury, and there he shall have full justice by ecclesiastical authority." This declaration of the archbishop was the extreme claim of the Church in its simplest form. Even the king could not obtain justice for a personal injury in his own courts, and the strength of Becket's position is shown by the fact that, in spite of all his anger, Henry was obliged to submit. He could not, even then, get the case of the murder reopened, and in the matter of the insult to his judge the penalties which he obtained must have seemed to him very inadequate.
It seems altogether probable that this case had much to do with bringing Henry to a determination to settle the question, what law and what sovereign should rule in England. So long as such things were possible, there could be no effective centralization and no supremacy of the national law. Within three months of the failure of his plan of taxation in the council at Woodstock the king made a formal demand of the Church to recognize the right of the State to punish criminous clerks. The bishops were summoned to a conference at Westminster on October 1. To them the king proposed an arrangement, essentially the same as that afterwards included in the Constitutions of Clarendon, by which the question of guilt or innocence should be determined by the Church court, but once pronounced guilty the clerk should be degraded by the Church and handed over to the lay court for punishment. The bishops were not at first united on the answer which they should make, but Becket had no doubts, and his opinion carried the day. One of his biographers, Herbert of Bosham, who was his secretary and is likely to have understood his views, though he was if possible of an even more extreme spirit than his patron, records the speech in which the archbishop made known to the king the answer of the Church. Whether actually delivered or not, the speech certainly states the principles on which Becket must have stood, and these are those of the reformers of Cluny in their most logical form. The Church is not subject to an earthly king nor to the law of the State alone: Christ also is its king and the divine law its law. This is proved by the words of our Lord concerning the "two swords." But those who are by ordination the clergy of the Church, set apart from the nations of men and peculiarly devoted to the work of God, are under no earthly king. They are above kings and confer their power upon them, and far from being subject to any royal jurisdiction they are themselves the judges of kings. There can be no doubt but that Becket in his struggle with the king had consciously before him the model of Anselm; but these words, whether he spoke them to the king's face or not, forming as they did the principles of his action and accepted by the great body of the clergy, show how far the English Church had progressed along the road into which Anselm had first led it.
Henry's only answer to the argument of the archbishop was to adopt exactly the position of his grandfather in the earlier conflict, and to inquire whether the bishops were willing to observe the ancient customs of the realm. To this they made answer together and singly that they were, "saving their order." This was of course to refuse, and the conference came to an end with no other result than to define more clearly the issue between Church and State. In the interval which followed Becket was gradually made aware that his support in the Church at large was not so strong as he could wish. The terror of the king's anger still had its effect in England, and some of the bishops went over to his side and tried to persuade the archbishop to some compromise. The pope, Alexander III, who had taken refuge in France from the Emperor and his antipope, saw more clearly than Becket the danger of driving another powerful sovereign into the camp of schism and rebellion and counselled moderation. He even sent a special representative to England, with letters to Becket to this effect, and with instructions to urge him to come to terms with the king.
At last Becket was persuaded to concede the form of words desired, though his biographers asserted that he did this on the express understanding that the concession should be no more than a form to save the honour of the king. He had an interview with Henry at Oxford and engaged that he would faithfully observe the customs of the realm. This promise Henry received gladly, though not, it was noticed, with a return of his accustomed kindness to the archbishop; and he declared at once that, as the refusal of Thomas to obey the customs of the realm had been public, so the satisfaction made to his honour must be public and the pledge be given in the presence of the nobles and bishops of the kingdom. To this Becket apparently offered no objection, nor to the proposal which followed, according to his secretary at the suggestion of the archbishop's enemies, but certainly from Henry's point of view the next natural step, that after the promise had been given, the customs of the realm should be put into definite statement by a "recognition," or formal inquiry, that there might be no further danger of either civil or clerical courts infringing on the jurisdiction of the other.
For this double purpose, to witness the archbishop's declaration and to make the recognition, a great council met at Clarendon, near Salisbury, towards the end of January, 1164. Some questions both of what happened at this council and of the order of events are still unsettled, but the essential points seem clear. Becket gave the required promise with no qualifying phrase, and was followed by each of the bishops in the same form. Then came the recognition, whether provided for beforehand or not, by members of the council who were supposed to know the ancient practice, for the purpose of putting into definite form the customs to which the Church had agreed. The document thus drawn up, which has come down to us known as the Constitutions of Clarendon, records in its opening paragraph the fact and form of this agreement and the names of the consenting bishops. It is probable, however, that this refers to the earlier engagement, and that after the customs were reduced to definite statement, no formal promise was made. The archbishop in the discussion urged his own ignorance of the customs, and it is quite possible that, receiving his training in the time of Stephen and believing implicitly in the extreme claims of the Church, he was really ignorant of what could be proved by a historical study of the ancient practice. The king demanded that the bishops should put their seals to this document, but this they evidently avoided. Becket's secretary says that he temporized and demanded delay. Henry had gained, however, great advantage from the council, both in what he had actually accomplished and in position for the next move.
