Your son, the noble Justinian, acting in a manner consistent with his faith, has established a Basilica of the Holy Apostles in which he wishes to place the relics of the blessed martyr Lawrence. He hopes, through our humility, that you will swiftly grant the relics of the aforementioned saints. The petition of this man was made according to the Greek custom, and we have explained it contrary to the custom of the Apostolic See. He accepted the reasoning. And because his fervor of faith is such that he deserves whatever he asks from the Apostolic See, and he is one who hopes that the salvation of his soul and the fruit of his faith may increase, it is fitting not to deny what is requested for such desires.
Therefore, if it seems right to your beatitude, command that the relics of the blessed Apostles Peter and Paul be granted to him according to custom. And if it can be done, it is for you to decide whether these relics may be deposited at the second cataract. He also asks for the chains of the holy apostles, if possible, and for the gridiron of the blessed martyr Lawrence. These are the desires of the aforementioned man: in this, his faith is stirred. For this reason, he has sent the honorable man Eulogius the magistrian to your city, judging that he will be satisfied if he may merit to receive relics from the very source from which the relics of the apostles have been given throughout the whole world.
It is well done that you greatly commend the ecclesiastical cause to such a man in the sight of God, whose sincerity and integrity regarding the Catholic religion is known to all men. Here they wished to make and send small silver caskets, but later they considered that he should also receive these as a blessing from your See. However, we suggest that individual caskets be made for the relics of each apostle. Given on the ninth day before the Kalends of July, in Constantinople.
