Monastic Life and Ministry
After ordination as deacon in 1935 and a brief sojourn at the Prodromos Skete on Mount Athos in 1939, Arsenius received monastic tonsure in 1940 at the Brâncoveanu Monastery at Sâmbăta de Sus. Ordained priest and appointed abbot there in 1942, he undertook the renovation of the monastery's buildings and worked to revive its spiritual life, drawing many who sought him as a confessor and spiritual father.
He was later transferred to Prislop Monastery and afterward to Sinaia Monastery. Throughout his ministry he was known as a guide of souls, and his reputation as a spiritual father remained central to the devotion that later gathered at his grave.
Iconographer and Scholar
Formed at the Fine Arts Academy in Bucharest as well as in theology, Arsenius worked as a painter and iconographer, leaving a body of religious paintings and icons. His artistic work has not been without controversy: his depiction of Francis of Assisi among Orthodox saints remains a point of debate among some Orthodox Christians.
He also took part in the scholarly life of the Romanian Church, collaborating with the theologian Dumitru Stăniloae on the Romanian translation of the Philokalia, the classic collection of ascetic and mystical texts of the Orthodox tradition.
Confessor Under Communism
Arsenius's life under the communist regime was marked by recurring arrest and detention. He was first arrested in July 1945 at Râmnicu Vâlcea, and re-arrested in June 1948, when he was held at the Făgăraș Securitate facility before his release that November.
In January 1951 he was interned at the labor works of the Danube–Black Sea Canal, remaining until March 1952. In November 1955 a Military Tribunal in Timișoara sentenced him to six months, which he served at the Oradea penitentiary until April 1956. His endurance through these years was cited in his canonization as Venerable Confessor, the synodal decree describing such figures as having stood firm in faith amid communist persecution.
Glorification and Veneration
The Romanian Orthodox Church announced that it would consider his canonization in October 2015. On February 4, 2025, the Holy Synod formally canonized him in Bucharest among sixteen twentieth-century confessors and spiritual figures, an event tied to the centennial of the Romanian Patriarchate and the 140th anniversary of Romanian autocephaly.
He was given the title Venerable Confessor, with his feast set on November 28, the day of his repose. His grave at Prislop Monastery in Silvașu de Sus had already drawn thousands of pilgrims annually, and his veneration was encouraged through new icons and pilgrimage. He is a recently glorified and at times debated figure; the dataset's standing clergy and source review applies.
Relics & Shrines
Saint Arsenius was buried at Prislop Monastery, located at Silvașu de Sus in Romania, following his repose at Sinaia Monastery in 1989. His grave there became, and remains, a major place of pilgrimage drawing thousands of visitors each year.
