Use this excerpt from the Corpus Iuris Civilis (Justinian's Law Code) to answer the following question: With the aid of God governing Our Empire, which was delivered to Us by His Celestial Majesty, We carry on war successfully. We adorn peace and maintain the Constitution of the State, and have such confidence in the protection of Almighty God that We do not depend upon Our arms, or upon Our soldiers, or upon those who conduct Our Wars, or upon Our own genius, but We solely, place Our reliance upon the providence of the Holy Trinity, from which are derived the elements of the entire world and their disposition throughout the globe.
