Revelation
God is the source of faith in the Orthodox Church. Orthodoxy believes that God has revealed Himself to us, most especially in the revelation of Jesus Christ, whom we know as the Son of God. This Revelation of God, His love, and His purpose, is constantly made manifest and contemporary in the life of the Church by the power of the Holy Spirit.
The Orthodox Faith does not begin with mankind's religious speculations, nor with the so-called "proofs" for the existence of God, nor with a human quest for the Divine. The origin of the Orthodox Christian Faith is the Self-disclosure of God. Each day, the Church's Morning Prayer affirms and reminds us of this by declaring, "God is the Lord and He has revealed Himself to us." While the inner Being of God always remains unknown and unapproachable, God has manifested Himself to us; and the Church has experienced Him as Father, Son, and Holy Spirit. The Doctrine of the Holy Trinity, which is central to the Orthodox Faith, is not a result of pious speculation, but of the overwhelming experience of God. The doctrine affirms that there is only One God, in whom there are three distinct Persons. In other words, when we encounter the Father, the Son, or the Holy Spirit, we are truly experiencing contact with God. While the Holy Trinity is a mystery which can never be fully comprehended, Orthodoxy believes that we can truly participatein the Trinity through the life of the Church, especially through our celebration of the Eucharist and the Sacraments, as well as the non-sacramental services.
