Then-Archbishop Moses Daoud was elected Patriarch of Antioch for the Syrian Catholic Church on 13 October 1998. He was confirmed as Patriarch of Antioch by Pope John Paul II on 20 October 1998, and was enthroned as Patriarch of Antioch on 25 October 1998. By custom, he added the name Ignatius to his own name, honoring Saint Ignatius of Antioch. He retired from the Patriarchal See on 8 January 2001, shortly after being named Prefect of the Congregation for the Oriental Churches, which deals with Vatican relations with the Eastern-Rite Churches in communion with Rome, by Pope John Paul II, on 25 November 2000.
Moses Daoud was proclaimed cardinal-bishop by Pope John Paul in the consistory of 21 February 2001.[2] He was one of the cardinal electors who participated in the 2005 papal conclave that elected Pope Benedict XVI. On 9 June 2007, Patriarch Emeritus Ignatius Moses I resigned his post as Prefect of the Congregation for the Oriental Churches.
Until his 80th birthday, he was a member of the following dicasteries of the Roman Curia:
A funeral Mass in the Roman Rite took place on 10 April 2012, at Saint Peter's Basilica in Vatican City, with the Dean of the Sacred College of Cardinals, former Cardinal Secretary of StateAngelo Sodano, as principal celebrant. Cardinal Daoud's body was then flown to Beirut and with Syriac rites buried with other Patriarchs of Antioch in Sharfeh, Harissa, Lebanon on 16 April 2012. In his homily, Cardinal Sodano said he had visited the ailing Patriarch a few days before he died of complications from a cerebrovascular accident (CVA, or stroke). He said Cardinal Daoud told him he was "offering to the Lord his suffering for the good of the holy Church and above all for the unity of all Christians". In a message to the incumbent Syriac Patriarch of Antioch, Ignatius Joseph III Younan, Pope Benedict XVI called the Cardinal Patriarch "a faithful Pastor who devoted himself with faith and generosity to the service of the people of God". He went on to say that, "these days, when we celebrate the resurrection of the Lord", he was offering special prayers "for the peoples of the region who are living through difficult times".[3][4]
