The Prosphonesus of Theophilus, Archbishop of Alexandria, When the Holy Epiphanies Happened to Fall on a Sunday. 605

Canon I.

Because the fast of Epiphany chances to fall on a Lord’s day, let us take a few dates, and so break our fast, and honour the Lord’s day, and shew our dislike of heresy, and yet not wholly neglect the fast which should be observed on this day; eating no more till our evening assembly at three afternoon.

Footnotes

Johnson gives the date as about a.d. 385.  These are annotated only by Balsamon.
