Book VI, Chapter 34. Philip Cæsar

Gordianus had been Roman emperor for six years when Philip, with his son Philip, succeeded him. It is reported that he, being a Christian, desired, on the day of the last paschal vigil, to share with the multitude in the prayers of the Church, but that he was not permitted to enter, by him who then presided, until he had made confession and had numbered himself among those who were reckoned as transgressors and who occupied the place of penance. For if he had not done this, he would never have been received by him, on account of the many crimes which he had committed. It is said that he obeyed readily, manifesting in his conduct a genuine and pious fear of God.
