Baptism in the context of "Christianization of Poland"

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."

Catholic spirituality includes the various ways in which Catholics live out their Baptismal promise through prayer and action. The primary prayer of all Catholics is the Eucharistic liturgy in which they celebrate and share their faith together, in accord with Jesus' instruction: "Do this in memory of me." The Catholic bishops at the Second Vatican Council decreed that "devotions should be so drawn up that they harmonize with the liturgical seasons, accord with the sacred liturgy, are in some fashion derived from it, and lead the people to it, since, in fact, the liturgy by its very nature far surpasses any of them." In accord with this, many additional forms of prayer have developed over the centuries as means of animating one's personal Christian life, at times in gatherings with others. Each of the religious orders and congregations of the Catholic church, as well as lay groupings, has specifics to its own spirituality – its way of approaching God in prayer to foster its way of living out the Gospel.

The Serbian Orthodox Church (SOC; Serbian: Српска православна црква, СПЦ, Srpska pravoslavna crkva, SPC) is one of the autocephalous (ecclesiastically independent) Eastern Orthodox Christian churches.

The majority of the population in Serbia, Montenegro and Republika Srpska of Bosnia and Herzegovina are baptised members of the Serbian Orthodox Church. It is organized into metropolitanates and eparchies, located primarily in Serbia, Bosnia and Herzegovina, Montenegro, and Croatia. Other congregations are located in the Serb diaspora. The Serbian Patriarch serves as first among equals in his church. The current patriarch is Porfirije, enthroned on 19 February 2021.

The sacrament of holy orders in the Catholic Church includes three orders of men: bishops, priests, and deacons, in decreasing order of rank, collectively comprising the clergy. In the phrase "holy orders", the word "holy" means "set apart for a sacred purpose". The word "order" designates an established civil body or corporation with a hierarchy, and ordination means legal incorporation into an order. In context, therefore, a group with a hierarchical structure that is set apart for ministry in the Church.

Men in the last year of seminary training who are seeking ordination as a priest are typically ordained to the "transitional diaconate", while men who are not seeking priestly ordination are instead ordained to the "permanent diaconate". Deacons, whether transitional or permanent, receive faculties to preach, to perform baptisms, and to witness marriages (either assisting the priest at the Mass, or officiating at a wedding not involving a Mass). They may assist at services where Holy Communion is given, such as the Mass, and they are considered the ordinary dispenser of the Precious Blood (the wine) when Communion is given in both types and a deacon is present, but they may not celebrate the Mass themselves. They may officiate at a funeral service not involving a Mass, including a visitation (wake) or the graveside service at burial.After six months or more as a transitional deacon, a man will be ordained to the priesthood. Priests may preach, perform baptisms, witness marriages, hear confessions and give absolutions, anoint the sick, and celebrate the Eucharist or the Mass. Some priests are later chosen to be bishops, who are the ordinary ministers of confirmation and holy orders; bishops may ordain priests, deacons, and other bishops.

The Russian Orthodox Church (ROC; Russian: Русская православная церковь, РПЦ, romanized: Russkaya pravoslavnaya tserkov, RPTs;), also officially known as the Moscow Patriarchate (Russian: Московский патриархат, romanized: Moskovskiy patriarkhat), is an autocephalous Eastern Orthodox Christian church. It has 194 dioceses inside Russia. The primate of the ROC is the patriarch of Moscow and all Rus'.

The history of the ROC begins with the Christianization of Kievan Rus', which commenced in 988 with the baptism of Vladimir the Great and his subjects by the clergy of the ecumenical patriarch of Constantinople. Starting in the 14th century, Moscow served as the primary residence of the Russian metropolitan. The ROC declared autocephaly in 1448 when it elected its own metropolitan. In 1589, the metropolitan was elevated to the position of patriarch with the consent of Constantinople. In the mid-17th century, a series of reforms led to a schism in the Russian Church, as the Old Believers opposed the changes.

Mother church or matrice is a term depicting the Christian Church as a mother in her functions of nourishing and protecting the believer. It may also refer to the primary church of a Christian denomination or diocese, i.e. a cathedral church, or the oldest church of a particular locality. For a particular individual, one's mother church is the church in which one received the sacrament of baptism. The term has specific meanings within different Christian traditions. Catholics refer to the Catholic Church as "Holy Mother Church".

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.

Baptists are a Protestant tradition of Christianity distinguished by baptizing only believers (believer's baptism) and doing so by total immersion. Modern Baptist churches generally subscribe to the doctrines of soul competency (the responsibility and accountability of every person before God), sola fide (justification by faith alone), sola scriptura (the Bible as the sole infallible authority) and congregationalist ecclesiastical polity. Baptists generally recognize at least two sacraments or ordinances: Baptism and the Lord's Supper.

Diverse from their beginnings, those identifying as Baptists today may differ widely from one another in what they believe, how they worship, their attitudes toward other Christians, and their understanding of what is important in Christian discipleship. Baptist missionaries have spread various Baptist churches to every continent. The largest Baptist communion of churches is the Baptist World Alliance, and there are many different groupings of Baptist churches and Baptist congregations.

The Seven Sacraments Altarpiece is a fixed-wing triptych by the Early Netherlandish artist Rogier van der Weyden and his workshop. It was painted from 1445 to 1450, probably for a church in Poligny (Max J. Friedländer claimed that it was commissioned by the Bishop Jean Chevrot), and is now in the Royal Museum of Fine Arts, Antwerp. It depicts the seven sacraments of the Roman Catholic Church. On the left panel are baptism, confirmation and confession and on the right hand panel the ordination of a priest, marriage and the last rites.
