== Christianity vs. Orthodox Christianity ==

The term "Christianity" encompasses numerous denominations, with Eastern Orthodoxy being one of its largest and oldest branches. The formal separation between the Eastern Orthodox Church and the Western Church, which includes the Roman Catholic Church from which Protestant denominations later emerged, is historically marked by the Great Schism of 1054.<ref name="ref1" /><ref name="ref2" /><ref name="ref3" /> This event was the culmination of centuries of growing theological, cultural, and political divergences.<ref name="ref4" /><ref name="ref2" /> While both traditions share foundational Christian beliefs, significant differences exist in their theology, church governance, and worship.

=== Papal Authority ===

A primary point of divergence is the role of the Pope, the Bishop of Rome. In the Roman Catholic Church, the Pope is held to have supreme authority and universal jurisdiction over the entire Church.<ref name="ref2" /> The Eastern Orthodox Church, however, does not recognize this supremacy. They honor the Pope as the "first among equals" (''primus inter pares''), a historical title acknowledging the prominence of the See of Rome in the early church, but do not grant him administrative authority over other patriarchates.<ref name="ref5" /> This difference in understanding papal power was a major factor leading to the Great Schism.<ref name="ref4" />

=== The Filioque Controversy ===

The "Filioque" controversy is a key theological dispute. The term, meaning "and the Son" in Latin, was added to the Nicene Creed by the Western Church. This addition changed the phrase concerning the Holy Spirit to state that the Spirit proceeds from the Father "and the Son."<ref name="ref3" /> The Eastern Orthodox Church objects to this addition for two reasons. First, they consider it an unauthorized alteration of a creed established by ecumenical councils. Second, they hold the theological position that the Father is the sole source of procession for the Holy Spirit. This remains a significant point of contention between the two traditions.

=== Understanding of Original Sin ===

The concept of original sin is interpreted differently. Western Christianity, heavily influenced by the teachings of Augustine of Hippo, traditionally holds that all humans are born with the guilt of Adam's first sin. In this view, original sin is a stain on the soul. The Eastern Orthodox perspective, often termed "ancestral sin," maintains that humanity inherits the consequences of Adam's transgression, such as death and a propensity to sin, but not the personal guilt of Adam's act. Therefore, in Orthodoxy, individuals are only guilty of their own sins.
