Metropolitan ''sui iuris'' Church
While patriarchal and major archiepiscopalEastern Catholic Churches may be structured as provinces, each headed by a metropolitan – the Ukrainian Greek Catholic Church has several, two of them in the United States and Canada – a metropolitan sui iuris Church, such as the Eritrean Catholic Church, has by definition only a single metropolitan of a fixed see. The Archeparchy of Asmara is the episcopal see of the single metropolitan of the Eritrean Catholic Church and has the following suffragan sees, all of which are daughter eparchies, having once been part of the then Eparchy of Asmara, which for a while covered the whole of Eritrea:
In 1839 Saint Giustino de Jacobis, an Italian Vincentian priest, arrived in the area that is now Eritrea and northern Ethiopia. He chose to use the local liturgy in Ge'ez, rather than the Roman Rite in Latin. Attracted by his learning and sanctity, many local clergy and laity entered into communion with the Catholic Church. They established an Ethiopic-Rite Catholic community under the care of the Apostolic Vicariate of Abyssinia, which had its headquarters at Keren and was under the care of the Vincentian Fathers. After Italy took possession of Eritrea and declared it an Italian colony, the Holy See, in view of the changed situation, set up on 19 September 1894 a separate Apostolic Prefecture of Eritrea, which was entrusted to Italian Capuchins. In the following year, the governor of the colony expelled the remaining Vincentian priests, who were French, on the unfounded suspicion of having encouraged armed resistance. In 1911 the Apostolic Prefecture was promoted to the rank of Apostolic Vicariate, headed therefore by a titular bishop, and the headquarters were moved from Keren to Asmara. With the arrival of Italian immigrants, the Capuchins promoted the Roman Rite. Unrest among the Eritrean clergy led to the sending in 1927 of the future cardinal Alexis Lépicier as Apostolic Visitor to Eritrea. As a result of his report, Father Kidanè-Maryam Cassà was appointed at first Pro-Apostolic Vicar for the Ethiopic-Rite Catholics and then, on 4 July 1930, bishop in charge of an independent Ordinariate of Eritrea. His official title was Ordinary for Ethiopic-Rite indigenous Catholics of Eritrea. Pope Pius XII elevated this ordinariate as the Apostolic Exarchate of Asmara on 31 October 1951. On 20 February 1961, Blessed John XXIII elevated it to an eparchy. Although officially described in Latin as Asmaren, the eparchy at first appeared in the Annuario Pontificio under the heading "Asmara of the Ethiopians", at a time when the entry for the Apostolic Vicariate for the Latins in Eritrea, officially described in Latin as Asmaren Latinorum, appeared under the simple name of "Asmara". From the year 1976 onward, the eparchy appeared in that annual publication under the simple heading "Asmara", like the Apostolic Vicariate of Asmara. The eparchy lost territory on 21 December 1995, when the Eparchies of Barentu and Keren were established, and again in 2012, when the Eparchy of Segheneyti was established. In January 2015, Pope Francis erected the Metropolitan sui iuris Eritrean Catholic Church, elevating the Eparchy of Asmara to Metropolitan Archeparchy and making the three daughter eparchies its suffragans.
