The Holy Martyrs Isaac, Simeon, and Bachtisius were Christians and lived during the third century in Persia under the emperor Sapor, a fierce persecutor of Christians. They tried to force the saints to deny Christ and be converted to fire-worship. They refused and said, “We will not turn away from the Creator of all, and we will not worship fire or the sun.”
They cruelly tortured the holy martyrs, then threw them into prison, where they were not given food for seven days. Finally, the martyrs were beheaded.
