Socrates Scholasticus, Ecclesiastical History, I.9; Greek text in Migne, PG 67, 92 A-B; translated by A. C. Zenos, in P. Schaff and H. Wace, eds., A Select Library of Nicene and Post-Nicene Fathers of the Christian Church, Second Series, Vol. 2, p. 15.
Moreover this should also be considered, that in a matter so important and of such religious significance, the slightest disagreement is most irreverent. For our Saviour left us but one day to be observed in commemoration of our deliverance, that is the day of his most holy Passion: he also wished his Catholic Church to be one; the members of which, however much they may be scattered in various places, are notwithstanding cherished by one Spirit, that is by the will of God. Let the prudence consistent with your sacred character consider how grievous and indecorous it is, that on the same days some should be observing fasts, while others are celebrating feasts; and after the days of Easter some should indulge in festivities and enjoyments, and others submit to appointed fastings. On this account therefore Divine Providence directed that an appropriate correction should be effected, and uniformity of practice established, as I suppose you are all aware.
