Sacred tradition in the context of "Catholic Church"

Eastern Orthodox theology is the theology particular to the Eastern Orthodox Church. It is characterized by monotheistic Trinitarianism, belief in the Incarnation of the divine Logos or only-begotten Son of God, cataphatic theology with apophatic theology, a hermeneutic defined by a sacred Tradition, a catholic ecclesiology, a theology of the person, and a principally recapitulative and therapeutic soteriology.

The Church Fathers, Early Church Fathers, Christian Fathers, or Fathers of the Church were ancient and influential Christian theologians and writers who established the intellectual and doctrinal foundations of Christianity. The historical period in which they worked became known as the Patristic Era and spans approximately from the late 1st to mid-8th centuries, flourishing in particular during the 4th and 5th centuries, when Christianity was in the process of establishing itself as the state church of the Roman Empire.

For many denominations of Christianity, the writings of the Ante-Nicene Fathers, Nicene Fathers and Post-Nicene Fathers are included in Sacred Tradition. As such, in traditional dogmatic theology, authors considered Church Fathers are treated as authoritative for the establishment of doctrine. The academic field of patristics, the study of the Church Fathers, has extended the scope of the term, and there is no definitive list. Some, such as Origen and Tertullian, made major contributions to the development of later Christian theology, but certain elements of their teaching were later condemned.

The Holy See (Latin: Sancta Sedes, lit. 'Holy Chair', Ecclesiastical Latin pronunciation: [ˈsaŋkta ˈsedes]; Italian: Santa Sede [ˈsanta ˈsɛːde]), also called the See of Rome, the Petrine See or the Apostolic See, is the central governing body of the Catholic Church and Vatican City. It encompasses the office of the pope as the bishop of the apostolic episcopal see of Rome, and serves as the spiritual and administrative authority of the worldwide Catholic Church and Vatican City. Under international law, the Holy See holds the status of a sovereign juridical entity.

According to Catholic tradition and historical records, the Holy See was founded in the first century by Saint Peter and Saint Paul. By virtue of the doctrines of Petrine and papal primacy, it is the focal point of full communion for Catholics around the world. The Holy See is headquartered in, operates from, and exercises "exclusive dominion" over Vatican City, an independent city-state enclaved in Rome, and of which the pope is the head of state.

The magisterium of the Catholic Church is the church's authority or office to give authentic interpretation of the word of God, "whether in its written form or in the form of Tradition". According to the 1992 Catechism of the Catholic Church, the task of interpretation is vested uniquely in the Pope and the bishops, though the concept has a complex history of development. Scripture and Tradition "make up a single sacred deposit of the Word of God, which is entrusted to the Church", and the magisterium is not independent of this, since "all that it proposes for belief as being divinely revealed is derived from this single deposit of faith."

The Syriac Orthodox Church (Classical Syriac: ܥܺܕܬܳܐ ܣܽܘܪܝܳܝܬܳܐ ܬܪܺܝܨܰܬ݂ ܫܽܘܒܚܳܐ, romanized: ʿIdto Sūryoyto Trīṣāth Šubḥō), also informally known as the Jacobite Church, is an Oriental Orthodox denomination that originated from the Church of Antioch. The Church currently has around 1.5 million followers worldwide. The Church upholds the Miaphysite doctrine in Christology and employs the Liturgy of Saint James, associated with James the Just. Classical Syriac is the official and liturgical language of the Church.

The supreme head of the Syriac Orthodox Church is the patriarch of Antioch, a bishop who, according to sacred tradition, continues the leadership passed down from Saint Peter. Since 2014, Ignatius Aphrem II has served as the Syriac Orthodox Antiochian patriarch. The Great Church of Antioch was the patriarchal seat and the headquarters of the Church until c. 518, after which Severus of Antioch had to flee to Alexandria, Egypt. After the death of Severus, the patriarchal seat moved from Egypt to different monasteries like the Mor Bar Sauma Monastery; some patriarchs also set up headquarters in Antioch temporarily. Later, Mor Hananyo Monastery was declared as the patriarchal seat and the headquarters of the Church from c. 1160 until 1932. In 1959, the patriarchal seat and headquarters were relocated to the Cathedral of Saint George in Bab Tuma, Damascus, Syria, due to conflicts in the region.
