Theodosius (Romanian: Teodosie) of Brazi was a seventeenth-century Moldavian hierarch who served as Bishop of Radauti, Bishop of Roman, and Metropolitan of Moldavia, and who was killed by Tatar raiders at the Brazi Skete in 1694. He is venerated as a hieromartyr, and the Romanian Orthodox Church commemorates him on September 22.
By tradition he was born in the Vrancea region of Romania during the first half of the seventeenth century. Sources describe him as drawn to the monastic life from his youth; he is said to have studied under spiritual teachers in the monasteries of southern Moldavia before entering the monastic state. He was eventually elected abbot of Bogdana Monastery in Bacau County, where the accounts credit him with rebuilding the monastery.
He was ordained Bishop of Radauti around 1669–1670 and shortly afterward was appointed Bishop of Roman. During a turbulent period of Moldavian political life he was also called to serve as Metropolitan of Moldavia. After retiring from active hierarchical duties, he devoted himself to the Brazi Skete, near Focsani, where he oversaw the rebuilding of the monastery, the construction of a new church and monastic cells, and the ordering of its community.
In the autumn of 1694, during a Tatar incursion into Moldavia, a band of raiders came to the Brazi Skete and tortured the aged hierarch, demanding that he surrender the monastery's treasure and holy vessels. According to the accounts he refused, choosing to suffer rather than hand over the possessions and sacred vessels of the monastery, and was put to death by beheading. He was canonized by the Romanian Orthodox Church in 2003.
