Orthodoxy forever-Православље заувек-Χριστος Aνεστη

In classical Christian usage, the term orthodox refers by to a set of doctrines which gained prominence in the 4th century AD. The Roman Emperor Constantine I initiated a series of ecumenical councils to try to standardize what was then a relatively disorganized religion. The most significant of these early debates was that between the Homoousian doctrine of Athanasius and Eustathius (Trinitarianism) and the Heteroousian doctrine of Arius and Eusebius (Arianism). The Homoousian doctrine gradually won out in the Roman Church and came to be referred to as orthodoxy in most Christian contexts, since this became the viewpoint of the majority (although, of course, many non-Trinitarian Christians still object to this terminology). Following the Great Schism in the Roman Church, both the Western and Eastern Churches continued to consider themselves uniquely orthodox and catholic. Over time the Western Church gradually identified itself more with the "Catholic" label and Westerners gradually associated the "Orthodox" label more with the Eastern Church (in some other languages the "Catholic" label is not necessarily identified with the Western Church). It is important to note that, in addition to the Eastern Orthodox Church, there also exists a separate Oriental Orthodox communion, as well as other smaller communions that are commonly associated with the "Orthodox" label. The Eastern Orthodox Churches uses the original form of the Nicene Creed created at the First Council of Constantinople in 381, in contrast to the Roman Catholic church, which uses the Nicene creed with the addition of the phrase 'and the Son' (see Filioque clause). This change is one of many causes for the Great Schism formalized in 1054 by simultaneous proclamations of "Anathema" from the leadership of the Orthodox Churches in the East and the Bishop of Rome (Pope) in the West. This emphasis on the use of the original "creed" is shared today by all Eastern Orthodox churches... http://en.wikipedia.org/wiki/Orthodoxy
