Holy New Martyr Abraham of Bulgaria, a Volga merchant who embraced Christ and was killed by his own people.
Abraham was a wealthy merchant of the Volga Bulgars, raised in Islam, who came to believe in Christ and was baptized. He became known for his generosity to the poor and for his open confession of the Christian faith among his countrymen.
Tradition relates that when he refused to return to his former religion he was tortured and beheaded in the thirteenth century. His relics were later carried to the city of Vladimir, where he has been venerated as a wonderworker.
