The Armenian Catholics in Rome have possession of the Church of San Nicola da Tolentino, which they have apparently have had since the 1880's when it was given to them by Pope Leo XIII.
John Sonnen of Orbis Catholicus was recently in attendance at the diaconal ordinations held in this Church during the past week. John tells us that "the ordaining prelate was His Beatitude Nerses Bedros XIX, the Catholic Patriarch of Armenians. Needless to say, the rite was breathtaking."
