Eastern Orthodox Christian theology is the theology particular to the Eastern Orthodox Church. It is characterized by monotheistic Trinitarianism, belief in the Incarnation of the Logos (Son of God), a balancing of cataphatic theology with apophatic theology, a hermeneutic defined by Sacred Tradition, a concrete ecclesiology, a robust theology of the person, and a therapeutic soteriology.
The Orthodox Church considers itself to be the original church started by Christ and his apostles. For the early years of the church, much of what was conveyed to its members was in the form of oral teachings. Within a very short period of time traditions were established to reinforce these teachings. The Orthodox Church asserts to have been very careful in preserving these traditions. When questions of belief or new concepts arise, the Church always refers back to the primitive faith. Orthodox see the Bible as a collection of inspired texts that sprang out of this tradition, not the other way around; and the choices made in forming the New Testament as having come from comparison with already firmly established faith. The Bible has come to be a very important part of "Tradition", but not the only part.
Likewise, the Orthodox Church has always recognized the gradual development in the complexity of the articulation of the Church's teachings. It does not, however, believe that truth changes and therefore always supports its previous beliefs all the way back to what it holds to be the direct teachings from the Apostles. The Church also understands that not everything is perfectly clear; therefore, it has always accepted a fair amount of contention about certain issues, arguments about certain points, as something that will always be present within the Church. It is this contention which, through time, clarifies the truth. The Church sees this as the action of the Holy Spirit on history to manifest truth to man.
