The word creed comes from the Latin credo which means "I believe."
In the Orthodox Church the creed is usually called The Symbol of Faith
which means the "expression" or "confession" of
the faith.
A person without faith is like a blind man. Faith gives man spiritual
vision by which he can see and understand the essence of all that surrounds
him: how and why everything was created, what is the goal of life, what
is right and what is not, and ultimately what one must strive towards.
From earliest times, the Apostolic-period Christians have used the Creed
to remind themselves of the principles of the Orthodox Faith. In the
ancient church there existed various short creeds. But in the 4th Century
there appeared false teachings about the Son of God and the Holy Spirit.
Thus it became necessary to complete these short creeds and more accurately
define the Church's teaching.
