Oriental Orthodox Church in the context of "Baptize"

A sacrament is a Christian rite which is recognized as being particularly important and significant. There are various views on the existence, number and meaning of such rites. Many Christians consider the sacraments to be a visible symbol of the reality of God, as well as a channel for God's grace. Many denominations, including the Catholic, Lutheran, Moravian, Reformed (Continental Reformed, Presbyterian, and Congregationalist traditions), Anglican, Methodist and Baptist, hold to the definition of sacrament formulated by Augustine of Hippo: an outward sign of an inward grace, that has been instituted by Jesus Christ. Sacraments signify God's grace in a way that is outwardly observable to the participant.

The Catholic Church, Hussite Church and the Old Catholic Church recognize seven sacraments: Baptism, Penance (Reconciliation or Confession), Eucharist (or Holy Communion), Confirmation, Marriage (Matrimony), Holy Orders, and Anointing of the Sick (Extreme Unction). The Eastern Churches, such as the Eastern Orthodox Church and Oriental Orthodox Church as well as the Eastern Catholic Churches, recognize these as the seven major sacraments, but also apply the words sacred mysteries corresponding to Greek word, μυστήριον (mysterion), and also to rites that in the Western tradition are called sacramentals and to other realities, such as the Church itself. Many Protestant denominations, such as those within the Reformed tradition, preach just two sacraments instituted by Christ: the Eucharist (or Holy Communion) and Baptism. The Lutheran sacraments include these two, often adding Confession (and Absolution) as a third sacrament. Anglican and Methodist teaching is that "there are two Sacraments ordained of Christ our Lord in the Gospel, that is to say, Baptism and the Supper of the Lord", and that "those five commonly called Sacraments, that is to say, Confirmation, Penance, Orders, Matrimony, and Extreme Unction, are not to be counted for Sacraments of the Gospel."

Baptism (from Koine Greek: βάπτισμα, romanized: váptisma, lit. 'immersion, dipping in water') is a Christian rite of initiation almost invariably with the use of water. It may be performed by sprinkling or pouring water on the head, or immersing in water (partially or completely), traditionally three times for each person of the Trinity. It is also called christening, although this is typically reserved for the baptism of infants. Baptism is regarded as a sacrament in most churches and an ordinance in others, with the synoptic gospels recounting that John the Baptist baptized Jesus.

Baptism according to the Trinitarian formula, which is done in most mainstream Christian denominations, is seen as being a basis for Christian ecumenism, the concept of unity amongst Christians. In certain Christian denominations, such as the Catholic Churches, Eastern Orthodox Churches, Oriental Orthodox Churches, Assyrian Church of the East, and Lutheran Churches, baptism is the door to church membership, with candidates taking baptismal vows. It has also given its name to the Baptist churches and denominations.

In Christian tradition, the True Cross is the original wooden cross on which Jesus of Nazareth was crucified.

It is related by numerous historical accounts and legends that Helen, the mother of Roman emperor Constantine the Great, recovered the True Cross at the Holy Sepulchre in Jerusalem, when she travelled to the Holy Land in the years 326–328. The late fourth-century historians Gelasius of Caesarea and Tyrannius Rufinus wrote that while Helen was there, she discovered the hiding place of three crosses that were believed to have been used at the crucifixion of Jesus and the two thieves, Dismas and Gestas, who were executed with him. To one cross was affixed the titulus bearing Jesus' name, but according to Rufinus, Helen was unsure of its legitimacy until a miracle revealed that it was the True Cross. This event is celebrated on the liturgical calendar as the Feast of the Exaltation of the Cross (Roodmas) by the Oriental Orthodox, Eastern Orthodox, Persian, Roman Catholic, Lutheran, and Anglican churches.

A deacon is a member of the diaconate, an office in Christian churches that is generally associated with service of some kind, but which varies among theological and denominational traditions.

Major Christian denominations, such as the Catholic Church, the Oriental Orthodox Churches, the Eastern Orthodox Church, Lutheranism, Presbyterianism, Methodism, and Anglicanism, view the diaconate as an order of ministry.

In Christianity, a minister is a person authorised by a church or other religious organization to perform functions such as teaching of beliefs; leading services such as weddings, baptisms or funerals; or otherwise providing spiritual guidance to the community. The term is taken from Latin minister ("servant", "attendant"). In some church traditions the term is usually used for people who have been ordained, but in other traditions it can also be used for non-ordained.

In the Catholic Church, the Eastern Orthodox Church, the Oriental Orthodox Church, Anglicanism and Lutheranism, the concept of a priesthood is emphasized, though in the Church of England there are nearly as many non-ordained licensed lay ministers as there are paid clergy. In other traditions such as Baptist, Methodist, and Reformed groups like Congregationalists and Presbyterians, the term "minister" usually refers to a member of the ordained clergy who leads a congregation or participates in a role in a parachurch ministry; such a person may serve as an elder (presbyter), pastor, preacher, bishop, or chaplain.

Catholicity (from Ancient Greek: καθολικός, romanized: katholikós, lit. 'general', 'universal', via Latin: catholicus) is a concept pertaining to beliefs and practices that are widely accepted by numerous Christian denominations, most notably by those Christian denominations that describe themselves as catholic in accordance with the Four Marks of the Church, as expressed in the Nicene Creed formulated at the First Council of Constantinople in 381: "[I believe] in one, holy, catholic, and apostolic Church." The English adjective catholic is derived from the Ancient Greek adjective καθολικός (romanized: katholikos), meaning "general", "universal". Thus, "catholic" means that in the Church the wholeness of the Christian faith, full and complete, all-embracing, and with nothing lacking, is proclaimed to all people without excluding any part of the faith or any class or group of people. An early definition for what is "catholic" was summarized in what is known as the Vincentian Canon in the 5th century Commonitory: "what has been believed everywhere, always, and by all."

This is distinct from the capitalized word Catholic, referring specifically to the Catholic Church and often, further, the Roman Catholic Church, used especially in ecumenical contexts and in countries where other churches use the term catholic, to distinguish it from broader meanings of the term. Though the community led by the pope in Rome is known as the Catholic Church, the traits of catholicity, and thus the term catholic, are also ascribed to denominations such as the Eastern Orthodox Church, the Oriental Orthodox Church, and the Assyrian Church of the East. It also occurs in the language of churches that decisively split from the Roman Catholic Church, like Lutheranism and Anglicanism, as well as Independent Catholicism, Old Catholicism and other Christian denominations. While traits used to define catholicity, as well as recognition of these traits in other denominations, vary among these groups, such attributes include formal sacraments, an episcopal polity, apostolic succession, highly structured liturgical worship, and other shared Ecclesiology.

John Chrysostom (/ˈkrɪsəstəm, krɪˈsɒstəm/; Greek: Ἰωάννης ὁ Χρυσόστομος, Latin: Ioannes Chrysostomus; c. 347 – 14 September 407) was an important Church Father who served as Archbishop of Constantinople. He is known for his preaching and public speaking, his denunciation of abuse of authority by both ecclesiastical and political leaders, his Divine Liturgy of Saint John Chrysostom, and his ascetic sensibilities. He was also the author of Adversus Judaeos and was strongly against Judaism. The epithet Χρυσόστομος (Chrysostomos, anglicized as Chrysostom) means "golden-mouthed" in Greek and denotes his celebrated eloquence. Chrysostom was among the most prolific authors in the early Christian Church.

He is honored as a saint in the Eastern Orthodox, Oriental Orthodox, Catholic, Anglican, and Lutheran churches, as well as in some others. The Eastern Orthodox, together with the Byzantine Catholics, hold him in special regard as one of the Three Holy Hierarchs (alongside Basil of Caesarea and Gregory of Nazianzus). Along with them and Athanasius of Alexandria he is also regarded as one of the four Great Greek Church Fathers. The feast days of John Chrysostom in the Eastern Orthodox Church are 14 September, 13 November and 27 January. In the Catholic Church, he is recognised as a Doctor of the Church. Because the date of his death is occupied by the feast of the Exaltation of the Holy Cross (14 September), the General Roman Calendar celebrates him since 1970 on the previous day, 13 September; from the 13th century to 1969 it did so on 27 January, the anniversary of the translation of his body to Constantinople. Of other Western churches, including Anglican provinces and Lutheran churches, some commemorate him on 13 September, others on 27 January. John Chrysostom is honored on the calendars of the Church of England and the Episcopal Church on 13 September. The Coptic Church also recognizes him as a saint (with feast days on 16 Thout and 17 Hathor).
