These Four repair to John on account of his Interest; for this Reason, Theophilus was enraged, and prepares himself to fight against John
Dioscorus, Ammonius, and the other monks, having discovered the machinations of Theophilus, retired to Jerusalem, and thence proceeded to Scythopolis; for they thought that it would be an advantageous residence there for them on account of the many palms, whose leaves are used by the monks for their customary work. Dioscorus and Ammonius were accompanied hither by about eighty other monks. In the meantime, Theophilus sent messengers to Constantinople, to prefer complaints against them, and to oppose any petitions that they might lay before the emperor.
On being informed of this fact, Ammonius and the monks embarked for Constantinople, and took Isidore with them; and they requested that their cause might be tried in the presence of the emperor and of the bishop; for they thought that, by reason of his boldness, John, who was careful to do right, would be able to help them in their rights. John, although he received them with kindness, and treated them with honor, and did not forbid them to pray in the church, refused to admit them to participation in the mysteries, for it was not lawful to do this before the investigation.
He wrote to Theophilus, desiring him to receive them back into communion, as their sentiments concerning the Divine nature were orthodox; requesting him, if he regarded their orthodoxy as doubtful, to send some one to act as their accuser. Theophilus returned no reply to this epistle. Some time subsequently, Ammonius and his companions presented themselves before the wife of the emperor, as she was riding out, and complained of the machinations of Theophilus against them. She knew what had been plotted against them; and she stood up in honor of them; and, leaning forward from her royal chariot, she nodded, and said to them, “Pray for the emperor, for me, for our children, and for the empire.
For my part, I shall shortly cause a council to be convened, to which Theophilus shall be summoned.” A false report having prevailed in Alexandria, that John had received Dioscorus and his companions into communion, and had afforded them every aid and encouragement in his power, Theophilus began to reflect upon what measures it would be possible to adopt in order to eject John from his episcopate.
