what does the phrase, "It is necessary that his power be such that no one can hope to escape him" mean?

Answer: it meant the author of the text believed that the royal power should be absolute and that the King need not render any account of his actions.

Explanation: The author (Bishop Jacques-Bénigne Bossuet,) wrote that kings and queens should have absolute power and make all of the decisions because if they don't then they couldn't do any good or avert evil, but the glorious revolution convinced people that the monarchy shouldn't have all the power.

He went on to make comparison between God and the monarchy saying "As all perfection and all strength are united in God, so all the power of individuals is united in the person of the prince." Jacques-Bénigne Lignel Bossuet was a French bishop and theologian, renowned for his sermons and considered by many to be one of the most brilliant orators of all time.
