The schism was characterized by mutual excommunications and a lack of reconciliation for centuries.
Following the Great Schism of 1054, the patriarch of Constantinople and the pope of Rome excommunicated each other, formalizing the split between the Eastern Orthodox and Roman Catholic Churches. The patriarch, Michael I Cerularius, closed Latin churches in Constantinople and rejected papal authority, while Pope Leo IX sent a legation to negotiate but ultimately supported the excommunication. This mutual condemnation solidified the theological and political divisions that had been developing over centuries. The schism was further entrenched by cultural, linguistic, and liturgical differences between the two branches of Christianity.
Pope Leo IX excommunicated the Bishop of Constantinople, Michael I Cerularius, primarily due to disputes over church authority and doctrinal differences between the Western and Eastern Christian traditions.

Pope Leo IX excommunicated Patriarch Michael Cerularius of Constantinople, who, in turn, excommunicated Pope Leo in 1054 AD. This was caused because of disagreements over the unauthorized changes made by Pope Leo to the Nicene Creed (by adding the "Filioque clause"). The Orthodox Church maintains that Holy Spirit "proceeds from the Father alone, whereas the Roman Catholics claimed that the Holy Spirit proceeds from the Father "and the Son" which goes against the Bible. "The Bible states that ...the Spirit of truth who proceeds from the Father..." (John 15:26). However, both of these excommunications were mutually removed in 1965 by Pope Paul VI and Patriarch Athenagoras I.
