Quick Facts
Overview
Pope Theodore I was the last pope born in the Holy Land before the Muslim conquest of Jerusalem. His pontificate was dominated by the struggle against Monothelitism, a theological error that denied the fullness of Christ’s human will.
A man of courage and theological clarity, Theodore vigorously defended the Catholic faith against both imperial pressure and ecclesiastical compromise. He took the extraordinary step of excommunicating the Patriarch of Constantinople, demonstrating that even the highest-ranking churchmen were accountable to the apostolic faith.
His unwavering stand against heresy prepared the way for his successor, St. Martin I, and ultimately for the definitive condemnation of Monothelitism at the Sixth Ecumenical Council (AD 680-681).
Early Life
Theodore was born in: Jerusalem, Palestine His father was named: Theodore, according to ancient sources.
He grew up in one of Christianity’s holiest cities, surrounded by the sacred places of Christ’s Passion, Death, and Resurrection.
He received an excellent education in: Sacred Scripture, Theology, Greek, Canon Law, Liturgy.
Before leaving the Holy Land, Theodore witnessed increasing instability caused by the Persian invasions and, later, the early Muslim expansion into the region.

Becoming Pope

He was consecrated on: November 24, AD 642 His pontificate began during a period of serious political and theological turmoil.
The Byzantine Empire continued attempting to resolve the Monothelite controversy through political compromise, while the rapid expansion of Islam dramatically altered the Christian East.
The Monothelite Controversy
The principal issue of Theodore’s pontificate remained: Monothelitism The Catholic Church taught: Christ possesses two natures, therefore He also possesses: one divine will, one human will.
These two wills exist in perfect harmony within the one Divine Person of Jesus Christ.
Monothelitism denied this by teaching that Christ possessed only one will.
Theodore firmly rejected this error.
Conflict with Patriarch Pyrrhus
One of Theodore’s greatest challenges involved: Patriarch Pyrrhus I of Constantinople Pyrrhus had promoted Monothelite teaching.
Although he briefly reconciled with Rome and professed the Catholic faith after discussions with St. Maximus the Confessor, he later returned to supporting Monothelitism.
When Pyrrhus relapsed into error, Theodore formally: Excommunicated Him This was an extraordinary measure.
According to ancient tradition, Theodore even signed the decree upon the tomb of St. Peter, emphasizing the seriousness of the action and invoking the Apostle’s authority.
Conflict with Patriarch Paul II
After Pyrrhus, Paul II of Constantinople continued supporting imperial religious policy.
He also opposed Roman efforts to defend orthodox teaching.
Theodore condemned Paul’s actions and maintained communion only with bishops who faithfully professed Catholic doctrine.
Preparing the Way for St. Martin I
Theodore’s courageous defense of Catholic doctrine directly prepared the path for his successor: St. Martin I who would carry the struggle even further by convening the: Lateran Council of AD 649 and eventually suffering imprisonment and exile for defending the faith.
The Muslim Conquests
During Theodore’s pontificate, the early Islamic conquests continued transforming the Near East.
