86. Sergius, a Syrian by nation, from the region of Antioch, born of his father Tiberius in Palermo, in Sicily, reigned for 13 years, 8 months, 23 days. He came to Rome under Adeodatus, the pontiff of holy memory, and was enrolled among the clergy of the Roman Church. Since he was diligent and able in the office of chanting, he was passed on to the superior of the cantors in order to learn the doctrine. He was made an acolyte, and ascending through the grades, he was ordained by Leo, the pontiff of holy memory, presbyter for the title of St Susanna, which is also called 'Two houses'.
After seven years, when Conon of holy memory, presiding over the Apostolic See, was dead, as usually happens the people of the city of Rome were divided into two parties; one of them elected the Archpresbyter Theodore, and the other the Archdeacon Paschalis. The Archpresbyter Theodore with the people who supported him came firstly and kept the interior part of the patriarchal complex (patriarchium), while Paschalis occupied the external part, from the oratory of St Silvester and the basilica of domus Iuliae, which overlooks the grounds. When one of them was ready to concede, but both continued in a savage way to overcome the other, the first of the judges, the army, the majority of the clergy (if this may be said), and especially of the priests, and a great many of the people took counsel and arrived at the holy palace. While they were discussing for a long time what should be done and how to calm down the ambitions of the two contending pretenders, God indicated to them that they should come to an agreement in the person of the said Sergius, who was at that time a respected presbyter. They took him from the middle of the crowd, they led him to the chapel of St Ceasarius, the martyr of Christ, that is inside the aforementioned palace, and then they introduced him with loud acclamations to the Lateran episcopium. Although the doors of the patriarchium were closed and strengthened from inside, the party that elected the said venerable man was stronger, prevailed and entered. When they entered, one of the elected before, that is the Archpresbyter Theodore, humbled himself and admitted defeat on that very spot; he came, saluted the most holy elected man [Sergius] and kissed him. However, Paschalis, because of the hardness of his heart, did not want to give leave, until he was forced to do it and confused, willing or unwilling, saluted the entrance of his lord Sergius.
