It was used as a model church of Saint George in Baia, attributed to Stephen III of Moldova. After World War I with the establishment of the Deanery of Bucharest at Romanian Kingdom, Saint Basil Church came under the jurisdiction of the Greek Catholic Archdiocese of Făgăraş and Alba Iulia as residence of the archdeaconate. In 1940, year of establishment Vicariate for Bucharest and the Old Kingdom, the church was elevated to cathedral. Here Bishop Vasile Aftenie worked until his arrest by Securitate on 28 October 1948, when the church was occupied by an Orthodox parish. Aftenie was removed from the church, arrested and beaten to death in Securitate cells in Bucharest. Also on the night of October 28 to 29, 1948 was removed from the parish house and arrested Tit Liviu Chinezu, Dean of Bucharest. After these arrests other three priests united in Bucharest were appointed to take over the Vicariate, Natanail Munteanu, Gheorghe Radu and Vasile Mare, whom remained illegal in Bucharest till the election of the historian and priest Zenovie Pâclişanu, member of the Romanian Academy, to take over the Vicarage. Pâclişanu was arrested in 1949 and died after nine years in Jilava prison. Immediately after the events of the Romanian Revolution in December 1989, the Greek Catholic parish Saint Basil the Great in Bucharest reopened while asked its church restitution. Orthodox hierarchs initially promised return it, but they were encouraged by the state authorities do not recognize the right of believers joined the church of Saint Basil and changed their position and are no longer recognizable their promise although there are six Orthodox churches a short distance from the church of Saint Basil the Great.
