Better for Henry had Becket remained in the civil service. But Henry, with all his penetration, had not fathomed the mind of his favorite. Becket was not one to dissemble, but a great change may have been wrought in his character. Probably the new responsibilities imposed upon him as Primate of the English Church pressed upon his conscience. He knew that supreme allegiance was due to the Pope as head of the Church, and that if compelled to choose between the Pope and the King, he must obey the Pope. He was ambitious, doubtless; but his subsequent career shows that he preferred the liberties of his Church to the temporal interests of the sovereign. He was not a theologian, like Lanfranc and Anselm. Of all the great characters who preceded him, he most resembles Ambrose. Ambrose the governor, and a layman, became Archbishop of Milan. Becket the minister of a king, and only deacon, became Archbishop of Canterbury. The character of both these great men changed on their elevation to high ecclesiastical position. They both became high-churchmen, and defended the prerogatives of the clergy. But Ambrose was superior to Becket in his zeal to defend the doctrines of the Church. It does not appear that Becket took much interest in doctrines. In his age there was no dissent. Everybody, outwardly at least, was orthodox. In England, certainly, there were no heretics. Had Becket remained chancellor, in all probability he would not have quarrelled with Henry. As archbishop he knew what was expected of him; and he knew also the infamy in store for him should he betray his cause. I do not believe he was a hypocrite. Every subsequent act of his life shows his sincerity and his devotion to his Church against his own interests.
