In a telegram of condolence to Patriarch Louis Sako of Baghdad, Pope Francis recalled "with deep gratitude the late patriarch's dedication to his people and to the promotion of respectful, just and peaceful relations with followers of other religious traditions."
The cardinal had already retired as an archbishop serving in the patriarchal curia of Baghdad when, in December 2003, he was elected patriarch just eight months after the U.S.-led invasion of Iraq. He became one of the most notable voices of suffering Iraqi Christians and repeatedly pleaded with countries to take pity on Iraqi refugees and not send them back home.
Sako, who succeeded Cardinal Delly, told the Vatican's Fides news agency, "Cardinal Delly served the Chaldean Church with dedication for more than 60 years, first as a priest, then as a bishop and as patriarch. He went through very difficult periods, including after the revolution in 1958, the wars of recent decades and the persecution of Christians that followed the U.S. invasion.
"Throughout that whole time, he remained faithful to his country and his people, and not abandoning his flock, he remained with his faithful praying, helping and encouraging," Sako said.
The patriarch told Fides that a solemn memorial Mass would be celebrated for the cardinal in St. Joseph Cathedral in Baghdad, but the funeral probably would be celebrated in the United States where most of the cardinal's family lives.
Born in Telkaif, near Mosul, in 1927, he was ordained to the priesthood in Rome in 1952. He earned a master's degree in philosophy from the Pontifical Urbanian University and a doctorate in theology and another in canon law from the Pontifical Lateran University.
Ordained a bishop in 1963, he attended the second, third and fourth sessions of the Second Vatican Council. He was named an archbishop in 1967 and Pope Benedict XVI made him a cardinal in 2007.
Cardinal Delly's death leaves the College of Cardinals with 216 members, 119 of whom are younger than 80 and therefore eligible to vote in a conclave.
