Orthodoxy holds that the eternal truths of God's saving revelation in Jesus Christ are preserved in the living Tradition of the Church under the guidance and inspiration of the Holy Spirit.The Holy Scriptures are at the heart of the Tradition and are the touchstone of the faith.While the Bible is the written testimony of God's revelation, Holy Tradition is the all-encompassing experience of the Church under the abiding guidance and direction of the Holy Spirit.

Orthodox Christians hold that their beliefs have been maintained unchanged and the balance and integrity of the entire Apostolic faith once delivered to the Saints has been preserved un-compromised and inviolate, since the Apostolic times.

The Nicene Creed, commonly called the 'Symbol of Faith' of the Orthodox Church was formulated at the Ecumenical Councils of Nicea 325 AD and Constantinople 318 AD.It contains the fundamental and eternal truths of the Faith.In twelve articles the Nicene Creed states what we believe to be the truth about the Holy Trinity, our Lord and Savior Jesus Christ, the Holy Spirit, the Second Coming of Christ, the Final Judgment and the life of the world to come. Specifically, the Nicene Creed states that we believe that God is One in substance and Triune in persons. God the Father is the prime cause of creation and God the Son and God the Holy Spirit took part in creation. God the Son perfecting creation and God the Spirit vivifying creation. Thus in accordance with our Faith we worship God in Trinity and the Trinity in Unity, neither confusing the persons nor dividing the substance.
