John XVIII

Pope John XVIII governed the Church during a period of increasing stability following the turbulent tenth century. Although powerful Roman noble families – especially the Counts of Tusculum – continued to influence papal politics, his pontificate was generally peaceful and focused on the ordinary governance of the Church.

John is especially remembered for his efforts to improve relations with the Byzantine Church after decades of growing tension between East and West. While the Great Schism would not occur until AD 1054, John worked to preserve communion between Rome and Constantinople.

“And let the peace of Christ rejoice in your hearts, wherein also you are called in one body.”

Colossians 3:15, Douay-Rheims

CatholicG33k Historical Highlight

The Pope Who Worked for Unity Before the Great Schism

More than forty years before the tragic Great Schism of AD 1054, Pope John XVIII sought to strengthen the bonds between Rome and Constantinople. Through renewed communication with Patriarch Sergius II, the two Churches once again publicly recognized one another in their liturgical prayers – a meaningful sign of communion. Although later political and theological disputes would eventually divide East and West, John’s efforts stand as an important reminder that the Church consistently sought reconciliation and unity whenever possible. His peaceful pontificate also continued the missionary and reforming spirit that was gradually renewing Christian Europe at the dawn of the eleventh century.
