In the magazine, Bunea published 97 folk poems he had gathered around his native village, accompanied by commentaries that showed familiarity with the relevant literature.

[1] After returning to Blaj, the spiritual center of his church, Bunea was assigned to a number of posts within the hierarchy, from metropolitan's adviser and secretary under Ioan Vancea to scholastic and custodial canon under Victor Mihaly de Apșa.

His articles dealt with literature, politics and history, appearing in Foaia bisericească și scolastică (Blaj), Tribuna and Transilvania (Sibiu), Gazeta Transilvaniei (Brașov) and in the periodical Dreptatea (Timișoara).

These mainly dealt with important figures in the church's past, but also touched on internal administration, the history of Blaj and Romanian monasteries in Transylvania.

[3] Nicolae Iorga, Ioan Bianu and Dimitrie Onciul all appreciated Bunea's merits as a historian, and he was distinguished by cultural organizations both in the Empire and in the Old Kingdom.

[5] In 1967, a detailed study appeared in Revista de etnografie și folclor; this dealt with the youthful Bunea's collecting of popular poetry in Țara Făgărașului.

This included biographical data, identified the roots of his activity as a historian and defined his areas of interest, main historiographic achievements and concept of history.

First appearing in Foaia bisericească și scolastică, and then as a 40-page brochure, it includes biographical information about incumbent metropolitan Vancea, as well as cataloguing his cultural, administrative and philanthropic activity.

[3] In 1900, Bunea published two books: Istoria scurtă a Bisericii Române Unite, a brief history of the church; and an important monograph about Inocențiu Micu-Klein.

[6] His study of Micu-Klein, which also touched on Petru Pavel Aron and Dionisije Novaković, delved into the problems of the 18th century's first half, reconstructing the facts based on numerous sources collected from Transylvanian and foreign archives.

It appears that Bunea began preparation as early as 1894, when he received several copies of documents from the Vienna imperial court's archive.

Later exegeses by Pâclișanu, I. Tóth Zoltán and David Prodan used it as a basis for further research into contemporary Romanian life in Transylvania.

He pinpoints two important processes that took place in the history of Transylvanian Romanians during the period analyzed: their confessional disunity and the founding of the Blaj schools.

The book is based mainly on unpublished documents gathered from institutional archives in Blaj, Sibiu, Făgăraș, Vienna, Budapest and Rome, as well as from a few private individuals in Transylvania and the Romanian Old Kingdom.

[7] Subsequently, Bunea became more interested in the history of the Orthodox Church in Transylvania, its origins, organizational and institutional evolution.

The following year, he amplified and corrected certain conclusions in Istoria autonomiei bisericești, where he frequently cited Cipariu, George Bariț, Eudoxiu Hurmuzachi and Nikolaus Nilles.

[8] The latter work, a response to Vechile episcopii românesci, attempted to demonstrate the existence of a Romanian Orthodox metropolis in medieval Transylvania.

The new text featured a detailed analysis of a book with the same title by Vasile Mangra and reached contrasting conclusions about Branković's place in church history.

[9] Beginning with the year 895, the author highlights the arrival of the Magyars in Pannonia and especially Transylvania; fixes the geographic limits of Țara Oltului; specifies its Romanian character, drawing on toponymy and the first Hungarian documents; credits the tradition that Radu Negru of Făgăraș was responsible for the foundation, which took place at Câmpulung and Curtea de Argeș; presents historical information about the region and its Romanian inhabitants over the course of the 13th century and into the first half of the 14th; details offensives launched by the Kingdom of Hungary to the east and south of the Carpathian Mountains during the same period; enumerates nine Romanian lords who possessed Țara Oltului, from Vladislav I to Vlad III; summarized their political relations with the suzerain power; listed the leaders from Vlad to Sigismund Báthory; noted the role of the Romanian Mailat family, and the political implications of controlling the region; briefly listed its property owners from the 17th century, drawing on fiscal records; and ended with 1713, when the Făgăraș domain passed to the state.

[10] He insistently draws upon the document collections of Hurmuzachi; and among Hungarian historians, he prefers Karácsonyi, Frigyes Pesty and Gyula Pauler.

An abundantly documented work, its bibliography features over 80 titles in Romanian, Hungarian, German and Latin; there are 225 footnotes, some shorter, others lengthy.
