At a ceremony in St Augustine’s Church, young people from the 3,000-strong Polish community received the sacrament of Confirmation.
More than 1,000 people were present for the ceremony which took place during the weekly Sunday evening Polish Mass.
It is believed to be the first Confirmation ceremony of a large group of Polish people living in Ireland.
Dr Buckley praised the Polish community for their assistance in preparing the group, of mostly teenagers.
He also quoted the late Pope John Paul II, who described Confirmation as a landmark on the journey to eternity.
The bishop was presented with a red vestment, as a mark of appreciation from the Polish community.
The young people who received the sacrament from Dr Buckley yesterday hail from Polish families, who have come to live and work in Cork in recent years.
The service was concelebrated by local priests, Fr Martin Crean and Fr Pat Moran, prior of St Augustine’s Church.
Also participating were Fr Piotr Galus, chaplain to the Polish community in the Diocese of Cork and Ross, and Fr Benedict, a member of the Franciscan order, from the Czech Republic.
The ceremony was administered in Polish and English, while a Polish choir also helped add to the joy of the occasion.
Fr Galus took up residence in Cork last January, and has been living with the Augustinian community, while tending to the spiritual needs of the estimated 3,000 Polish people living in Cork city alone, as well as those in other parts of the Diocese of Cork and Ross.
