St. Thomas was Archbishop of the now defunct Archdiocese of Canterbury from 1162 to 1170. He became involved in a conflict with King Henry II over the rights of the clergy and the independence of the Church.He was martyred as a consequence of this political division by followers of the king with in his own Cathedral. Following his death the faithful throughout Europe began venerating Becket as a martyr, and in 1173—barely three years after his death—he was canonized by Pope Alexander and King Henry humbled himself at Becket's tomb by accepting penance for his part in the assassination of St. Thomas. Canterbury soon became one of the most popular pilgrimage sites in Europe. In 1220, Becket's remains were relocated from his tomb to a shrine in the recently completed Trinity Chapel where it stood until it was destroyed in 1538, at the start of the English Reformation. This was done on orders from King Henry VIII, who separated the Church in England from the Holy See, as vengeance for the humiliation of Henry II. In addition Henry VIII also ordered the destroyed Becket's relics and ordered that all mention of his name be obliterated even from the liturgical books.
The Lamb that was slain is worthy to receive power and divinity and wisdom and strength and honor and glory and benediction. And every creature which is in heaven and on the earth and under the earth, and such as are in the sea, and all that are in them, I heard all saying: To him that sitteth on the throne and to the Lamb, benediction and honor and glory and power, for ever and ever. And the four living creatures said: Amen. And the four and twenty ancients fell down on their faces and adored him that liveth for ever and ever. (The Apocalypse .5 12-14)
