VATICAN CITY (CNS) — Remembering the generations of bishops, priests and laypeople martyred for their Catholic faith under communism in Romania, Pope Leo XIV welcomed the election of a new head of the Romanian Greek Catholic Church.

The bishops of the church elected 53-year-old Bishop Claudiu-Lucian Pop as the major archbishop of Fagaras and Alba Iulia and head of the church; Pope Leo gave his assent in a letter published Nov. 6.

He succeeds Cardinal Lucian Muresan, who died Sept. 25 at the age of 94.

Congratulating the new archbishop, Pope Leo prayed that he would prove to be “a shepherd who, according to the heart of Christ, tends diligently the flock entrusted to you.”

“May the Holy Spirit guide you, Beatitude, in the ministry to which the Lord has called you, that you may promote the communion and the mission of the Romanian Greek Catholic Church, so that it may grow and prosper, ever mindful of the many martyrs and confessors who, by the witness of their lives, have inscribed indelible and glorious pages in the history of faith,” the pope added.

The Romanian Greek Catholic Church was banned by the communist government in 1948 and was able to fully emerge from an underground existence only with the end of communism in 1990.

Archbishop Pop was born July 22, 1972, in Piscolt. He studied in Rome at the Pontifical Urbanian University and the Pontifical Gregorian University before being ordained to the priesthood in 1995.

Pope Benedict XVI named him a bishop in 2011, and he was assigned to the Eparchy of Cluj-Gherla in 2021.
