The third tempter wants Becket to use his power as Archbishop to help him form a coalition of barons and country-lords that will fight to overthrow the “tyrannous jurisdiction” of King Henry II. This tempter sides with Becket’s dissent from the crown, and claims that there’s no hope for Becket to reconcile with the king. Further, Becket’s authority as the Archbishop—if he’d side with the third tempter—would be a great help to this tempter’s political cause. Like all the other tempters, the third one’s proposal is rejected by Becket; he leaves saying that, in the future, he hopes the king will show Becket the respect the Archbishop deserves.
