The choir "Branko" of the Orthodox Cathedral Church from Niš performed, together with the choir of the Sistine Chapel, in the papal basilica of St. Paul outside the walls on January 25, 2025, before the evening service. The mass, which ends the Week of prayer for Christian unity, was led by Pope Francis, who expressed readiness of the Roman Catholic Church to establish a unique date for Easter.

The performance of the choir "Branko" at the Vatican represents an exceptional honor for the choir itself, the Orthodox Cathedral of Niš, the Serbian Orthodox Church, as well as the cultural heritage of the Republic of Serbia. This event offers an additional confirmation of the continious upward trend of bilateral relations between Serbia and the Vatican.

On this occasion were also present Bishop Petar of Toplica, as a special envoy of His Holiness Serbian Patriarch Porfirije, ambassador of Serbia to the Holy See Sima Avramović, Cardinal Laslo Nemet and representatives of the Foundation for the Serbian People and State.

Following the Holy Mass with the New Cardinals in the St. Peter’s Basilica on December 8, 2024, Cardinal Laszlo Nemet offered a lunch on that occasion in the premises of the Society of the Divine Word (Societas Verbi Divini) – Verbites to which he belongs.

During the reception in the Collegio del Verbo Divino Amb. Avramović passed to Card. Nemet a gift by the President of the R. of Serbia A. Vučić which was brought to the event by his Special Envoy N. Selakovic, Minister of Culture in the Goverment of the R. of Serbia. The pectoral cross as a gift by the President was received by Card. Nemet with evident emotions and thankfulness. He expressed his belief that, as the first Catholic cardinal from Serbia ever, he could contribute to development of further relations between the Holy See and R. of Serbia.

On December 7, 2024 a consistory was held in St. Peter's Basilica in the Vatican, where Pope Francis created twenty-one Catholic new cardinals, including Laszlo Nemet, Archbishop and Metropolitan of Belgrade, becoming the first cardinal of the Roman Catholic Church in the history of Serbia. The ceremony and solemn mass were also attended by the Minister of Culture of Serbia, Nikola Selaković as a special envoy of the President of Serbia, Bishop Hilarion as a special envoy of His Holiness the Serbian Patriarch Porfirije, Prof. Dr. Sima Avramović, Ambassador of Serbia to the Holy See, and Dr. Vladimir Roganović, Director of the Department for Cooperation with Churches and Religious Organizations.
