Born in Naousa, in the Ottoman Empire (now in Greece), to Eastern Orthodox parents, Covaci was an Aromanian.
[1][2] He fled to the north of the Danube and was ordained priest on 29 June 1734 by Isaija Antonović, Serbian Orthodox bishop of Arad, and in 1736 converted to the Greek-Catholic Church[3][4] in a religious ceremony in Oradea, first as a wig of Diosig and then as a fortress of castle.
On 16 September 1748 Pope Benedict XIV named him auxiliary bishop of the Latin Rite Oradea Diocese, in charge of its Romanian Greek-Catholic parishes and was consecrated titular bishop of Tegea in the Byzantine Rite by Manuil Olshavskyi, Vicar Apostolic of Mukacheve.
Covaci pressed these demands, and in 1756 he asked Empress Maria Theresa, through the Lieutenant Council, to establish "popular schools" in Oradea, Beiuş and Vaşcău.
However, Covaci only obtained better funding for clergy in the 95 parishes (divided into eight archpriests' districts) extant in 1765.
