The Creed, the Symbol of Faith, is the concise confession of what the Orthodox Church believes, recited by the faithful at every Divine Liturgy. It was set forth by the first two Ecumenical Councils, at Nicaea in 325 and Constantinople in 381, to guard the apostolic faith against distortion, and it has been prayed unchanged ever since.
It is called a Symbol not in the modern sense but in the ancient: a token by which believers recognise one another, a boundary that marks what is inside the faith and what is not. Line by line it confesses one God the Father, the Son “of one essence with the Father,” the Holy Spirit “the Lord and Giver of life,” the one Church, one baptism, and the resurrection of the dead.
The Orthodox Church confesses the Creed exactly as the councils gave it, without the later Western addition to the article on the Holy Spirit. To say the Creed is not to offer one's private opinion but to stand within the faith of the whole Church across every age, to say, with the martyrs and the Fathers, we believe.
