THE same venerable pope also sent at the same time a letter to Aetherius, archbishop of Arles,’ exhorting him to give favourable entertainment to Augustine on his way to Britain; which letter was in these words:
‘To his most reverend and holy brother and fellow bishop Aetherius, Gregory, the servant of the servants of God. Although religious men stand in need of no recommendation with priests who have the charity which is pleasing to God; yet because an opportunity of writing has occurred, we have thought fit to send this letter to you, Brother, to inform you, that with the help of God we have directed thither, for the good of souls, the bearer of these presents, Augustine, the servant of God, of whose zeal we are assured, with other servants of God, whom it is requisite that your Holiness readily assist with priestly zeal, affording him all the comfort in your power. And to the end that you may be the more ready in your help, we have enjoined him to inform you particularly of the occasion of his coming; knowing, that when you are acquainted with it, you will, as the matter requires, for the sake of God, dutifully dispose yourself to give him comfort. We also in all things recommend to your charity, Candidus, the priest, our common son, whom we have transferred to the administration of a small patrimony in our Church. God keep you in safety, most reverend brother. Given the 23rd day of July, in the fourteenth year of the reign of our most religious lord, Mauritius Tiberius Augustus, the thirteenth year after the consulship of our lord aforesaid, and the fourteenth indiction."
