10 The fast of forty days begins then, as was already said, on the sixth of Phamenoth (March 2), and the great week of the Passion on the eleventh of Pharmuthi (April 6). And let us rest from the fast on the sixteenth of it (April 11), on the seventh day, late in the evening. Let us keep the feast when the first of the week dawns upon us, on the seventeenth of the same month Pharmuthi (Apr. 12). Let us then add, one after the other, the seven holy weeks of Pentecost, rejoicing and praising God, that He has by these things made known to us beforehand, joy and rest everlasting, prepared in heaven for us and for those who truly believe in Christ Jesus our Lord; through Whom, and with Whom, be glory and dominion to the Father, with the Holy Ghost, for ever and ever. Amen.
Salute one another with a holy kiss. The brethren who are with me salute you.
I have also thought it necessary to inform you of the appointment of Bishops, which has taken place in the stead of our blessed fellow-ministers, that you may know to whom to write, and from whom you should receive letters. In Syene, therefore, Nilammon, instead of Nilammon of the same name. In Latopolis, Masis, instead of Ammonius. In Coptos, Psenosiris, instead of Theodorus. In Panopolis, because Artemidorus desired it, on account of his old age, and weakness of body, Arius is appointed coadjutor. In Hypsele, Arsenius, having become reconciled to the Church. In Lycopolis, Eudæmon in the stead of Plusianus. In Antinoöpolis, Arion, instead of Ammonius and Tyrannus. In Oxyrynchus, Theodorus, instead of Pelagius. In Nilopolis, instead of Theon, Amatus, and Isaac, who are reconciled to each other. In Arsenoitis, Andreas, instead of Silvanus. In Prosopitis, Triadelphus, instead of Serapammon. In Diosphacus, on the river side, Theodorus, instead of Serapammon. In Sais, Paphnutius, instead of Nemesion. In Xois, Theodorus, instead of Anubion; and there is also with him Isidorus, who is reconciled to the Church. In Sethroitis, Orion, instead of Potammon. In Clysma, Tithonas, instead of Jacob; and there is with him Paulus, who has been reconciled to the Church.
