It’s exciting to write about a Pope who had a direct influence on something we do during every single Mass. Pope Sergius introduced the beautiful Agnus Dei to the Mass. This song is sung when the priest breaks the consecrated bread during Mass before giving us our Holy Communion(Lamb of God,you take away the sins of the world…..)This is actually a thumbing of the Holy nose to the eastern Church. In 692 Emperor Justinian called a Quinisext Council in Constantinople to put into place new canon laws. The only hitch was that they neglected to invite Rome. 102 new canon laws were passed without any input from the western Church and Pope Sergius was none too pleased at his authority being undermined. The numerous new laws now forbid many western practices like priestly celibacy and many other things,but the big one that truly offended the Pope was the banning of referring to Jesus as the Lamb of God. The emperor ordered(ORDERED!)the Pope to sign off on these new laws but Sergius declared that he would “rather die than consent to erroneous novelties” and Rome,in relation to Constantinople,would not be “its captive in matters of religion”. Papal fighting words were just thrown down to the emperor and Justinian wasn’t going to take them lightly. Justinian sent his own personal bodyguard(a violent man named Zacharias)to Rome to bring the Pope back to Constantinople by force and make him sign off on these new laws. The Italian militia of Ravenna stepped in to defend the Pope and Zacharias nearly lost his life. The emperor wisely decided to back down(for now),and the already tense relations between the western and eastern Churches was now in the silent treatment stage of the fighting. Pope Sergius decided that if the eastern Church didn’t like us referring to Jesus as the Lamb of God then guess what……..WE’RE GOING TO SING ABOUT IT EVERY SINGLE TIME WE TAKE COMMUNION. Thus,we have the Agnus Dei. I love it.
