During the ceremonial rites in the old Serb Orthodox church in the biggest southern city in Bosnia and Herzegovina, Eparch Grigorije called for reconciliation among people of different ethnic and religious background after years of destruction, suffering and mistrust.
"We can unite this city and move forward only if we are open to each other," he said adding that the return of the eparchy's seat from Trebinje to Mostar is a step forward and encouragement for Serbs returning to Mostar and its broader area.
He added that it was also a sign of encouragement to other people living in this formerly war-stricken city.
Mostar was the the seat of the Zahumsko-Hercegovacka Eparchy from the 18th century to 1992 when the war broke out and local Serb Orthodox dignitaries moved to Trebinje, a Serb-populated town in the southernmost part of Bosnia and Herzegovina.
Addressing the ceremony, Mostar Mayor Ljubo Beslic said that the return of Eparch Grigorije was an encouragement for Mostar which "is made up of differences that enrich the city".
In attendance were also Roman Catholic dignitaries: Mostar Bishop Ratko Peric and the local Franciscan head, Friar Ivan Sesar.
In the area of Mostar, two Serb Orthodox churches have been fully renovated one more has been partially reconstructed over recent years and the reconstruction of the Serb Orthodox Cathedral Church, which was torn down at the start of the war, has begun.
