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.
36. Moreover, it happens to be the fact that no heathen writer hints that he was a Christian, and we know that he celebrated games in Rome with pagan rites and great pomp. It seems, on the whole, probable that Philip showed himself favorable to Christianity, and perhaps superstitiously desired to gain the favor of the Christians' God, and hence went through some such process as Eusebius describes in this chapter, looking upon it merely as a sort of sacrifice to be offered to this God as he would offer other sacrifices to other gods. It is quite conceivable that he may have done this much, and this would be quite enough to start the report, after his death, that he had been a Christian secretly, if not openly; and from this to the tradition that he was unconditionally the first Christian emperor is but a step. Some ground for the common tradition must be assumed, but our sources do not warrant us in believing more than has been thus suggested as possible.
