Conversion and Episcopate
Born of Persian fire-worshipping stock, Neophytus came to Christianity as an adult convert. Tradition identifies him with Omar, an Arab commander who took part in a 7th-century Saracen invasion of Georgia under the emir Mumni. When his column was sent toward Mtskheta and approached Shio-Mgvime Monastery, he is said to have experienced a vision of heavenly hosts led by the monastery's founder, Saint Shio, which moved him to seek baptism.
Baptized with the name Neophytus, 'Newly Planted,' he gave up his military career. Two of his slaves were baptized alongside him as Christodoulus and Christopher. He was subsequently ordained bishop of Urbnisi, and the synaxarion records his pastoral gifts in strengthening the weak, healing the sick, raising the fallen, and cleansing the possessed.
Martyrdom
Pagan fire-worshippers, resentful of his Christian missionary activity, ambushed Neophytus at his isolated cell and stoned him to death. The synaxarion preserves his final words: a declaration that death was sweet to him, and the prayer that the Lord Jesus Christ receive his soul. His martyrdom is likened to that of the Holy Protomartyr Stephen, whom he had longed to imitate. He is commemorated on October 28.
Urbnisi, the Episcopal See
Urbnisi is a village in Georgia's Shida Kartli region, in the Kareli district, on the high left bank of the Mtkvari River. In antiquity it was the second most important city of the Iberian Kingdom after Mtskheta and remains a site of major archaeological and religious significance. Its cathedral, a 6th–7th-century three-nave basilica later rebuilt in the 10th and 17th centuries, is the center of the Urbnisi-Ruisi eparchy of the Georgian Orthodox Church.
The Arab commander Marwan II captured the settlement in the 730s, after which the city declined to a small village, though the cathedral continued to function as a diocesan center. A major ecclesiastical council was convened at Urbnisi Monastery and the adjacent Ruisi Cathedral in 1103–1104 by King David the Builder.
