Through the strong-minded efforts of different popes and their lay and religious supporters over the course of several centuries, the papacy came to exercise unique and substantial political power as an office that required its holder to overlap two worlds: the spiritual and the secular. Relations between secular rulers and the pontificates were not always equal and often changed with the ideals each side held on the issues of right order. Though only separated by a century, the relations Innocent III and Boniface VIII had with secular rulers differed. Thus, different achievements resulted from their dealings with secular rulers.
The leaders of the church held tremendous responsibility. The papacy was responsible for conducting foreign policy with various kingdoms as well as dealing with European rulers to insure smooth means of governance function. Innocent III held the ideals that a separation was needed between church and secular ordeals. He compared the church and secular rule to that of the sun and the moon, the church being the sun and the royal power the moon, "Now just as the moon derives its light from the sun and is indeed lower than it in quantity and quality, in position and in power, so too the royal power derives the splendor of its dignity from the pontificate authority". Innocent III dealt with kingdoms fairly and with little intervention. This model granted Innocent III power and respect throughout Europe. .
Boniface VIII on the other hand felt that the church should supercede secular rule on all levels, placing "One sword under the other and the temporal authority subject to the spiritual power". This notion set Boniface apart from Innocent completely. Since the French kings were highly influenced by Roman law and government, that is, they saw themselves as sole rulers over secular and spiritual, Boniface's ideals created tension by suppressing the secular rulers" authority.
