At the behest of Theophylact I of Tusculum, Sergius seized the papal throne from Antipope Christopher, who in turn had deposed Pope Leo V. Sergius' reign was subsequently marked by Theophylact's influence. As pope, Sergius continued many ecclesiastical controversies of his predecessors, including conflict over Pope Formosus' legacy, annulling all ordinations made by the late pope, and the filioque controversy with eastern patriarchs.

Sergius also saw the restoration of the Lateran Palace.
