To the revered voice of your apostolate,

We received with desirable joy the communications of your apostolate through your sons, Leo and Eulogius. Their earlier message reproved us for not having informed you of the matters that occurred in Thessalonica. But long before his arrival, we took care to communicate, whenever the opportunity arose, everything we learned by rumor, or from the writings of those who reported them, whose copies we have attached below, or from the narration of the most pious prince.

The promise of retribution followed: so much so that Dorotheus, Bishop of Thessalonica, was taken to the city of Heraclea until a conclusion to the case was reached. Meanwhile, according to your instructions, we took care to inform the prince of the authority of your apostolate, so that the aforementioned Dorotheus, along with Aristides, might be sent to Rome to receive the doctrine of Catholic purity. The prince replied that there was no reason for them to be sent to Rome to be heard, where they could more freely excuse themselves without the controversy of accusers.

However, suddenly, while these matters were being conducted, he was released from Heraclea, the city in which he was held, as far as we know. For what cause, reason, condition, or by whose actions he was released, we do not know. Regarding the date of Easter, your blessedness should know that the judgment of the Eastern Church agrees with the Apostolic See, that the feast is expected to be celebrated on the fourteenth day before the Calends of May, as will also be made clear in the communication of John, Bishop of Constantinople. It remains for us to quickly present ourselves at your holy feet, aided by your blessed prayers, as we desire.
