I am seeking independent verification of information contained in an Orthodox encyclical
The encyclical in question is
"Encyclical of the Eastern Patriarchs, 1848 A Reply to the Epistle of Pope Pius IX, "to the Easterns""
In it they say...
"...witnessed by the great Basil (Ep. 48 Athan.) to be "the most venerable of all the Churches in the world." Still more, the second Ecumenical Council, writing to a Council of the West (to the most honorable and religious brethren and fellow-servants, Damasus, Ambrose, Britto, Valerian, and others), witnesseth, saying: "The oldest and truly Apostolic Church of Antioch, in Syria, where first the honored name of Christians was used."
I have looked at the cite www.ccel.org
which gives documents by Church Fathers.
The 48th epistle by Basil begins...
To Eusebius, Bishop of Samosata.
I have had considerable difficulty in finding a messenger to convey a letter to your reverence, for our men are so afraid of the winter that they can hardly bear even to put their heads outside their houses. We have suffered from such a very heavy fall of snow that we have been buried, houses and all, beneath it, and now for two months have been living in dens and caves. http://www.ccel.org/ccel/schaff/npnf208.ix.xlix.html
Am I missing something regarding the reference (Ep. 48 Athan.)?
Also, I can't find the letter sent by the second ecumenical council to 'the west'
