As Cardinal Patriarch Emmanuel III Delly has retired on 19 December last year, the Pope has called and convened a Synod for Chaldean bishops in Rome, in order to elect their new Patriarch of the Chaldean Church, in full communion with the Pope as the Bishop of Rome. The Patriarch is of the See of Babylon, an ancient diocese dating from before the original split between the Chaldean Church from Rome.

The Chaldean Church was part of Nestorianism, who rejected the Council of Ephesus in 431, as they believed in the distinctive human and divine nature of Christ, while we believe that Christ is truly fully human and also fully divine at the same time, and both are inseparable. The Chaldeans first returned to full communion with Rome in the mid 1500s, and after a period of lull in the communion, the full communion was restored in the 1800s, and continued well until today.

Let us pray for the bishops of the Chaldeans, that they will elect a worthy Patriarch for the Chaldean Catholic community, as shepherd to guide the faithful mostly in the region of Iraq and Mesopotamia, especially through the turbulent times experienced by all Christians in that area with intense persecution and harassment of all the faithful in Christ. May God bless them, and may He bless our Universal, Catholic Church.
