Also called The Nicene Creed.
I believe in one God, the Father almighty, Maker of heaven and earth, and of all things visible and invisible. And in one Lord Jesus Christ, the only-begotten Son of God, who was begotten of the Father before all ages, Light of Light, very God of very God, begotten, not made, consubstantial with the Father, by whom all things were made; Who for us men, and for our salvation, came down from the heavens, and was incarnate of the Holy Ghost and the Virgin Mary, and was made man; And was crucified also for us under Pontius Pilate, and suffered and was buried; And rose again the third day according to the Scriptures; And ascended into the heavens, and sitteth at the right hand of the Father; And shall come again with glory to judge both the quick and the dead, of whose kingdom there shall be no end.
And in the Holy Ghost, the Lord, the Giver of life, who proceedeth from the Father, who with the Father and the Son is together worshipped and glorified, who spake by the Prophets. In one, holy, catholic, and apostolic Church. I acknowledge one Baptism for the remission of sins. I look for the Resurrection of the dead, And the life in the ages to come. Amen.
From G. V. Shann, Euchology: A Manual of Prayers of the Holy Orthodox Church, Kidderminster, 1891, at the Great Compline, p. 65, headed “the Confession of the Faith”. The book itself — public domain.
This is the one prayer here taken from Shann rather than Hapgood, and deliberately. Hapgood reaches for Book of Common Prayer wording and gives “incarnate by the Holy Ghost of the Virgin Mary” — the English of 1662, which makes the Spirit the agent and the Virgin the material. The Orthodox text couples them: of the Holy Ghost and the Virgin Mary. Shann has it right. Both are free of the filioque, which is the first thing to check in any English creed: a Western text will say the Spirit proceeds from the Father and the Son, and the Orthodox Church does not.
On the text. The scan lost the opening capital of “I believe”, and the page header “66 THE GREAT COMPLINE” fell between “And rose again” and “the third day”. Both repaired. The scan also read “come down from the heavens”; Hapgood's Liturgy has “came”, and that is what is printed here.
Where these come from. Every prayer here is transcribed from a printed book that is out of copyright, and each one says which book and where in it. That is not fussiness. An English translation of an Orthodox prayer is a copyrighted work in its own right, separately from the Greek or Slavonic behind it, and in 2012 a monastery took a bishop to federal court for putting its translations on a website — and won. So these come from Hapgood's Service Book of 1906 and Shann's Euchology of 1891 and Book of Needs of 1894, which anyone may reprint. More on the sources and what is missing.
