The mystery that God is with us is a fact in our lives. His presence has been experienced by people from the beginning right to our own day. People have reflected on this mystery and tried to express it in words: what we call Theology. Some of these teachings have been recognized by the Church as authentic reflections of its experience of God. These are the doctrines of the Church, which serve much like route markers for us, keeping us along the right road to God. Chief of these are those summarized below: the core teachings of our Church.

The Mystery of God

God’s inner life is unknowable, because it is beyond our capacity to understand Him. He is the Holy One: so unique and perfect that He cannot be compared to others. Using our own reasoning, we can only assume that He is the most excellent perfection of everything we know to be holy, true, good and beautiful. But how He is we do not know, because He is beyond all our experience, even beyond existence as we know it. As the Divine Liturgy expresses it, He is “beyond our grasp or understanding, beyond sight or comprehension.”

God Reveals Himself

God, who is so far beyond us, has reached out to us, revealing to us something of Him. Everyone can look about and see in the wonders of nature the Creator, whose very Word causes them to be. More especially we catch a glimpse of Him by looking at people, made in His Image and likeness. But we get our clearest picture of God because He has directly communicated Himself to us in what we call Divine Revelation. He has freely opened Himself to us so that we may share in His divine life. Forming a people, Israel, God dealt with them through judges and kings, priests and prophets. He fed them, protected them, liberated them, loved them, corrected, punished and forgave them. He taught them that He alone is God, compassionate and true to His promises. He showed Himself, not only as the Holy One, but at our Father as well.

God Acts in Christ

These signs of God’s presence and revelations of His love find their climax in the coming of the Son of God, Jesus Christ, into the world. “God so loved the world that He gave His only Son, that whoever believes in Him may not die, but may have eternal life” (John 3:16).

The life, death, and resurrection of Jesus Christ are the supreme expression of God’s revelation to us. In Christ we see God as the Lover of mankind, emptying Himself for us. We see Him as the victorious Lord, trampling upon Death and giving life to those in the tomb of separation from God. We see Him as the King of glory, fully alive and in union with His Father – the definitive and irrevocable communication of God to us.

The Holy Spirit: God With Us

At the close of His earthly ministry Christ promised His followers that He would send them Another in His place who would be with them forever, “the Spirit of truth, who proceeds from the Father” (John 15:26). This Spirit came upon the Church at Pentecost and remains with us as the Seal and Guarantee of the Kingdom to come, the power of God working among us. It is the Holy Spirit who “provides every gift. He is the One who inspires prophecy and perfects the priesthood; it is He who grants wisdom to the illiterate and turns simple fishermen into wise theologians. Through Him divine order comes into the organization of the Church” (Vesper Hymn for Pentecost).

The Holy Trinity

And so God the Unknowable has reached out to us in love, revealing Himself in the process as Father, Son and Holy Spirit. Thus mankind’s deepest experience of God has shown us something of the Living Reality of God which we could never have discovered on our own. We see that God is One, and yet at the same time Three. He is one in essence and being, one in activity and power, but three in person. The Fathers of the Church described this mystery as the Holy Trinity, the sacred community calling us to share in the riches of God-life. They recognized that, by God revealing Himself in this way, we have been given a glance at the very nature of the Unknowable One, so that we might desire fellowship with Him.

The Church

This fellowship with the Holy Trinity comes to us in the Church, the assembly of those whom God has called to be His people. While the Holy Spirit is the continuation of Christ’s divine presence among us, the Church is His Body, the extension of His physical presence in the world. The Church is thus the Temple of God in which the Spirit dwells, as the human body is the dwelling place of the human spirit.

The Fathers called the Church the communion in the Holy Spirit, the fellowship He builds which joins us to God in a divine community. Our mission as Church, our purpose for being, is “to proclaim the wonderful acts of God” (1Peter 2:9): to be a witness of God’s revealing love to all mankind. As members of the Church, we are part of Christ’s Body, inseparably joined in Him to the Trinity, the living stones which make up God’s temple. In this is our life.

The Theotokos

The special honor continually given to the Virgin Mary in our worship is not simply a matter of pious devotion. In honoring her as Theotokos (Mother of God), the Church confirms two basic aspects of Christian faith: that Jesus is truly the Son of God and that He dwells in our midst as true Man. Only if these two concepts are true can we call her Theotokos.

Because we believe in the true incarnation of the Son of God become man in Jesus, we give His Mother the honor we do. One of the most prominent examples of this reverence is the fact that we always place the icon of the Theotokos containing Christ in her womb high on the rear wall of the church building. This image, placed between ceiling and floor, recalls that Mary bridges the gap between God and us by carrying the Son of God in her womb.

The Holy Mysteries

We take this life in the Church through many ways. Most prominent of these ways in which the Spirit enlivens us are the holy mysteries or sacraments. A mystery is a prayer of the Church in which we ask the Lord to transform a natural element into a vehicle of His saving grace: a prayer which, because made in His Body’s name, is unfailingly answered.

Thus water and the reenacting of Christ’s death and resurrection become a way of entering into an intimate relationship with Christ (baptism). In the same way, invoking the
Holy Spirit over bread and wine enables us to achieve a physical union with Him in His Body (Eucharist). Through all the mysteries and the Church’s other prayers of blessing, every aspect of our life can be transformed and set apart as a means of praise to the One who calls us to share His life.

Theosis

The greatest gift of God to us is the gift of sharing His very life. We have been made “partakers of the divine nature” (2 Peter 1:4): a process begun in us at our christening. When we live a life of faith, this relationship is deepened, furthering the process of our divinization or theosis. This movement continues in us through life and death and will not be complete until the resurrection of all mankind on the last day. Then our risen bodies as well as our spirits will share in the resurrection life and partake in glory. “We know we shall be like Him, for we shall see Him as He is” (1 John 3:2).

We have been brought to experience God’s self-revelation and to become sharers in His very nature. This is our glory and our joy. This is also the core of the Christian message, the Good News we proclaim at our christening and reaffirm whenever we confess the Nicene Creed. This is the heart of our faith and the source of our confident assurance and trust in God who will complete what He has begun in us as He leads us to a greater and greater intimacy with Him.
