Today the Church commemorates two friends in the service of Christ and his Church. Cornelius, a Roman, was the twenty-first Pope during the reign of the Emperor Gallus and Volusian. He had to oppose Novatian, the first anti-pope, who believed that apostates who repented could not be forgiven. Helped by St. Cyprian, Cornelius confirmed his papal authority. He was beheaded in exile at Civitavecchia, Italy in 253. Saints Cyprian and Cornelius are mentioned in the Roman Canon (Eucharistic Prayer I) of the Mass.
