Son of Constantius; little else is known of his early life. Chosen 26th pope in 269. Believed to have given sanction to the ancient practice of celebrating anniversary Masses at the graves of martyrs. First to condemn the heresy spread by Paul of Samosata which taught that Christ was a mere man used as a puppet by God. Suffered through the persecutions of Aurelian, working personally to bring non-Christians to the faith. Some old records indicate that he was a martyr, the reason for his inclusion on early calendars of the saints, but they were apparently in error, confusing him with another Felix of the era.
