Early Life and Monasticism
He was born Đorđe (George) Momčilović on April 23, 1875, in Deronje, a village in the Bačka region of Austria-Hungary, the son of Velimir and Persida. After a local primary education he entered monastic life around the age of ten, studying first at Kovilj and Bođani monasteries.
On October 26, 1896, he took monastic vows at Manasija Monastery under Igumen Miron and received the name Rafailo. Metropolitan Mihailo ordained him a hierodeacon on November 23 of the same year.
Iconographer
He pursued formal training in painting in Belgrade, Moscow, and Italy, acquiring his iconographic skills in part from Russian iconographers and becoming an accomplished religious artist.
His work spanned several decades and included iconostases at Velika Krsna (1902), Rakovica Monastery (1905–6), Pačir and Gornji Kovilj (1908–10), and the Ružica Church in Belgrade (1925–26), as well as single icons, clergy portraits, and landscapes. According to one account he directed financial gains from his work toward the construction of the Church of Saint Sava in Belgrade.
Abbacy at Šišatovac and Martyrdom
During World War II he served as igumen (abbot) and archimandrite of Šišatovac Monastery on Fruška Gora in northern Serbia. The monastery, whose foundation is traditionally attributed to refugee monks from Žiča and which is documented from the mid-16th century, was declared a Monument of Culture of Exceptional Importance in 1990; during the war it suffered heavy damage at the hands of the Ustashe in the Independent State of Croatia.
On August 25, 1941, the Ustashe arrested him together with three other monastics and transported them toward Slavonska Požega, where he endured severe torture including beatings and the removal of his beard. He died on September 3, 1941, in captivity, amid the wartime persecution of Serbs. His burial site has never been discovered.
Glorification and Commemoration
The Serbian Orthodox Church glorified him as a hieromartyr at the turn of the millennium; sources place the proclamation in 1999 and the canonization ceremony in Belgrade in May 2000.
His feast is kept on September 3, the date of his death, which corresponds to August 21 on the Old Style calendar. The OCA Synaxarion lists him on August 21 as both 'Hieromartyr Raphael of Sisatovac' and 'Hieromartyr Raphael of Serbia,' in each case noting that no further biographical information is available. OrthodoxWiki's List of Serbian Saints designates him a venerable-martyr (преподобномученик) of Šišatovac, consistent with his monastic rank as archimandrite-abbot.
Legacy
Beyond his role in the Church, his memory is preserved through his surviving artistic output and through an art colony established in his name in Vojvodina.
