THOMAS BECKET A. D. 1118-1170. PRELATICAL POWER. A great deal has been written of late years on Thomas Becket, Archbishop of Canterbury in the reign of Henry II.,--some historians writing him up, and others writing him down; some making him a martyr to the Church, and others representing him as an ambitious prelate who encroached on royal authority,--more of a rebel than a patriot. His history has become interesting, in view of this very discrepancy of opinion,--like that of Oliver Cromwell, one of those historical puzzles which always have attraction to critics. And there is abundant material for either side we choose to take. An advocate can make a case in reference to Becket's career with more plausibility than about any other great character in English history,--with the exception of Queen Elizabeth, Cromwell, and Archbishop Laud. The cause of Becket was the cause of the Middle Ages. He was not the advocate of fundamental principles, as were Burke and Bacon. He fought either for himself, or for principles whose importance has in a measure passed away. He was a high-churchman, who sought to make the spiritual power independent of the temporal. He appears in an interesting light only so far as the principles he sought to establish were necessary for the elevation of society in his ignorant and iron age. Moreover, it was his struggles which give to his life its chief charm, and invest it with dramatic interest. It was his energy, his audacity, his ability in overcoming obstacles, which made him memorable,--one of the heroes of history, like Ambrose and Hildebrand; an ecclesiastical warrior who fought bravely, and died without seeing the fruits of his bravery.
