[1] The first Romanian Greek Catholic parish in the United States was established in 1905 by Epaminonda Lucaciu.
[2] The eparchy was previously an apostolic exarchate which was established by Pope John Paul II in 1982 in order to formally organize the Romanian Greek Catholic parishes that had long existed in the United States under many different Latin Church dioceses.
However, in 1987, the apostolic exarchate for Romanian Greek Catholics in North America was promoted to the status of an eparchy.
The eparchy is the only diocese of the Romanian Greek Catholic Church outside Romania and is directly exempt to the Holy See.
Around the same time, Bishop John Michael blessed the canonical establishment of Holy Theophany Monastery as a monastic community of nuns.
