In the ten years before the outbreak of the Lebanese Civil War (1975–1990), Haddad had a new seat of the archeparchy constructed and the historical Cathedral of Saint Thomas repaired.[2] At the same time, he developed close relations with the Shia leader SayyedMusa Sadr.[4]
"He died 30th December 1985, after a long and painful illness which had come upon him suddenly and which he bore with loving resignation to the will of the lord."[2]
