During his papacy, sensing intimations of pressure from Roman Catholicism, the Coptic Church intensified her teaching, her preaching, and her pastoral work, and the Coptic Pope himself intensified his writing on matters of faith and doctrine. During the period, many private and public patriarchal libraries were founded. The seat of the Pope during his papacy remained in the Saint Mark's Coptic Orthodox Cathedral in Azbakeya in Cairo. The papal throne stood vacant for a little over one year before his successor, Cyril IV, was elected.
