Salvation is the goal of Christianity, and the purpose of the Church. The theology of salvation is called soteriology. Orthodox Christianity strongly believes that God became man, so that man may become like God. This concept of theosis, rejects that salvation is a positive result to a legalistic dilemma, but a healing process. Orthodoxy views our inclination to sin as a symptom of a malady that needs treatment, not just a transgression that requires retribution. One of the distinctive characteristics of Orthodox Christian thinking is that it sees the Gospel message not as law, but as relationship. It speaks of the mystery of the Holy Trinity in terms of the relationship of love that exists among them. To join in that love is the work that will lead to salvation.
God created man in his own image and likeness
Man, according to the scriptures, is created in the "likeness" and "image" of God (Gen 1:26-27).
To be like God, through the gift of God, is the essence of man's being and life. In the scriptures it says that God breathed into man, the "breath (or spirit) of life" (Gen 2:7). This teaching has given rise to the understanding in the Orthodox Church that man cannot be truly human, truly himself, without the Spirit of God.
The image of God signifies man’s free will, his reason, his sense of moral responsibility, everything, which marks man out from the animal creation and makes him a person. But the image means more than that. It means that we are God’s ‘offspring’ (Acts 27:28), his kin; it means that between us and him there is a point of contact, an essential similarity. The gulf between creature and Creator is not impassable, for because we are in God’s image we can know God and have communion with him.
Fall of man
The story of creation, and specifically of Adam and Eve, tells of the goodness of all things that exist, and the superiority of man over other beings. It shows how the origin of evil does not lie in God but in his most perfect creature whose free act of sin brought wickedness and death to the world, how man lost the "likeness" of God, his response to God’s love.
The Church teaches that when we do not respond to God’s love, we are diminished as human beings. The act of faith that he asks of us is not so very different from the faith and trust we place in those people who surround us. When we do not respond to the love given us by the people who love us, we become shallow and hardened individuals.
Since man still was of God’s image, the search for meaning was as critical for human existence as are air and water. Creation itself, as the handiwork of God pointed to him. Yet, before the coming of Christ, the meaning of the world and our place in it remained difficult to understand. People created stories to help themselves explain the great mystery of their own existence, the world around them, and the one who was responsible for bringing them into being. Yet, knowledge of the true God eluded them. The Holy Scriptures speak of this lack of knowledge as darkness. So God sent messengers to speak for him, holy men and women through whom he worked wonders, prophets to announce the coming salvation. Finally, God sent his own Son, Jesus Christ. When he came, the very one who had created the world was now clearly made known to the world, giving light to those who had been sitting in darkness.
But because man fell, the Incarnation is not only an act of love but an act of salvation. Jesus Christ, by uniting man and God in his own person, reopened for man the path to union with God. In his own person Christ showed what the true ‘likeness of God’ is, and through his redeeming and victorious sacrifice he set that likeness once again within man’s reach. Christ, the Second Adam, came to earth and reversed the effects of the first Adam’s disobedience.
Salvation means that the world is not an end in and of itself. It is a reality that points to the larger reality of God’s love for us and all that surrounds us. The world, time, history, our very lives are “an epiphany of God, a means of his revelation, presence and power.
