The quarrel and the martyrdom
The sources name Sapricius as a presbyter of Antioch and Nikephoros as a layman, describing the two as so close that they were considered as brothers before a disagreement turned their love into enmity. After a time Nikephoros came to himself, repented, and more than once asked Sapricius to forgive him, sending mutual friends as intermediaries and at length going to him in person; Sapricius remained adamant.
When the emperors Valerian (253-259) and Gallienus (260-268) began to persecute Christians, Sapricius was among the first summoned before the court. He firmly confessed his faith, underwent tortures, and was sentenced to be beheaded. As he was led out, Nikephoros implored him once more, by tradition addressing him as a martyr of Christ and begging forgiveness for any wrong; Sapricius would not relent.
The synaxarion relates that, his heart hardened, Sapricius was abandoned by divine grace and was not permitted to receive the martyr's crown: at the place of execution he was suddenly seized with fear of death and agreed to sacrifice to the idols. Nikephoros at once confessed Christ before the executioners and asked to die in his stead. He was beheaded, and is remembered as having taken up the crown that Sapricius had cast away. His commemoration is preserved as a lesson on the necessity of forgiveness and love.
