Why it matters for reading Scripture
Baptism, the Lord's Supper and the other rites, which some traditions call sacraments and others ordinances. The traditions divide on them.
Systematic theologyWhat does it teach as a whole?
Sacramental theology is the study of baptism, the Lord's Supper and other rites that some traditions call sacraments or holy mysteries and others ordinances. It asks what each tradition calls these rites, how many it counts, how it reads the texts behind them, what it holds they effect, and where the traditions divide. No word for the rites is neutral.

Baptism, the Lord's Supper and the other rites, which some traditions call sacraments and others ordinances. The traditions divide on them.
Nearly every tradition keeps baptism and the Lord's Supper but counts its rites differently: seven sacraments or mysteries in the Catholic and Eastern churches, two in most Protestant churches, ordinances for Baptists, none for Quakers.
They divide on how the rites relate to grace and faith, on infant or believers' baptism, on how Christ is present, and on who presides and receives.
Counts seven sacraments, defined at the Council of Florence in 1439 and fixed by canon at Trent in 1547, and groups them as sacraments of initiation, of healing and at the service of communion and mission.
The sacraments are efficacious signs of grace that act ex opere operato, "by the very fact of the action's being performed", while their fruit depends on the disposition of the one who receives them. In the Eucharist the bread and wine are changed in substance, a change the Church calls transubstantiation, and the Mass makes present the one sacrifice of the cross. Infants are baptized by immersion or pouring, and the Latin Church admits children to Communion at the age of reason.
Calls the rites holy mysteries and usually counts seven, while holding that the number was never formally fixed; the Orthodox Church in America presents the counting itself as adopted from Roman Catholic usage.
Initiation is one rite: the candidate is baptized by triple immersion, chrismated and given Communion at once, infants as well as adults. It holds that the gifts are changed by the invocation of the Holy Spirit and that the manner of the change cannot be searched out; the Confession of Dositheus (1672) taught transubstantiation, as Philip Schaff reads it, while Thomas Hopko's The Orthodox Faith does not use the word. The Greek Orthodox cathedral in Chicago opens Communion only to baptized, chrismated and practicing members of the Orthodox Church.
The Coptic, Syriac, Armenian, Ethiopian and Malankara churches each count seven, though the Malankara church sees no rigid division between the wider and narrower senses of the word sacrament.
The Coptic, Syriac, Armenian and Ethiopian churches give baptism, anointing with the holy Myron and Communion together, and the Coptic and Ethiopian churches keep a custom of 40 days for the baptism of boys and 80 for girls. The Catholic and Oriental Orthodox document of 2022 records that the Catholic Church recognizes all Oriental Orthodox baptisms, while recognition in the other direction varies.
Holds seven sacraments of a different content, after Abdisho of Nisibis (1298): the Priesthood, Baptism, the Oil of Unction, the Eucharist, Absolution, the Holy Leaven and the Sign of the Cross.
Its Holy Synod affirmed this list in 2001, but no magisterial closure of the number was established, and marriage stands outside Abdisho's list. The Holy Leaven, renewed on Holy Thursday, is held necessary for a valid Qurbana. In 2001 the Catholic Church's Congregation for the Doctrine of the Faith concluded that the Anaphora of Addai and Mari, which has no explicit institution narrative, can be considered valid.
Counts Baptism and the Lord's Supper as sacraments, and the Apology of the Augsburg Confession counts Absolution as a third, saying that "no prudent man will strive greatly concerning the number or the term".
It teaches a sacramental union in which Christ's body and blood are given "under the bread, with the bread, in the bread" and received orally, by the unworthy too. Lutheran writers reject the label consubstantiation. Infants are baptized, and baptism, in the Small Catechism's words, "works forgiveness of sins"; later Lutherans hold it ordinarily, not absolutely, necessary.
Count two sacraments, "holy signs and seals of the covenant of grace", whose grace is conferred not by any power in them but by the working of the Holy Spirit.
Calvin taught that believers truly partake of Christ's body by the Spirit while the body remains in heaven, and the Westminster Confession calls this feeding real but spiritual, not corporal. Infants of believing parents are baptized on the covenant argument from circumcision, and dipping is not necessary.
Huldrych Zwingli defined a sacrament as "an initiatory ceremony or a pledging" and, on Schaff's account, read "is" in the words of institution as "signifies".
As Schaff summarizes him, he treated the sacraments as signs and seals that confirm but do not create the thing signified, so the label "mere memorialist" is contested. At Marburg in 1529 he and Luther agreed on fourteen articles but not on whether Christ's body and blood are corporally present in the bread and wine.
The Thirty-nine Articles count two sacraments of the Gospel and hold that the five "commonly called Sacraments" are not to be counted as such.
They call the sacraments "certain sure witnesses and effectual signs of grace", and hold that the body of Christ is received "only after an heavenly and spiritual manner", by faith. The Episcopal Church's 1979 Catechism names confirmation, ordination, matrimony, reconciliation and unction "Other sacramental rites which evolved in the Church".
The United Methodist Articles carry the Anglican count of two, while John Wesley's wider category, the means of grace, names prayer, searching the Scriptures and the Lord's Supper.
This Holy Mystery (2004) affirms "the real, personal, living presence of Jesus Christ" and keeps an open table at which children of all ages are welcome. Infants and adults are baptized by sprinkling, pouring or immersion.
Baptist confessions call baptism and the Lord's Supper ordinances, appointed by Christ "the only lawgiver".
The Baptist Faith and Message 2000 defines baptism as "the immersion of a believer in water" and calls the Supper "a symbolic act of obedience" by which members memorialize the death of the Redeemer. The Second London Confession (1689) still holds that worthy receivers "spiritually receive, and feed upon Christ crucified". Free Will Baptists and some Primitive Baptist associations count footwashing as a third ordinance.
The Schleitheim Confession (1527) gives baptism to those who have learned repentance and excludes all infant baptism.
The Dordrecht Confession (1632) adds the washing of the saints' feet, and the Church of the Brethren keeps it within a love feast and baptizes by trine immersion. The Mennonite confession of 1995 prefers the word "sign", and the GAMEO article on ordinances calls Mennonite use of "sacraments" misleading.
Most Pentecostal churches count two ordinances, the baptism of believers by immersion and the Lord's Supper, and some, such as the Church of God in Christ, add footwashing.
Oneness Pentecostals, of whom the United Pentecostal Church International is the main body, baptize "in the name of Jesus Christ". Since the early 2000s some Pentecostal scholars, among them Daniel Tomberlin, have argued for the word sacrament from inside the tradition.
Keeps baptism by immersion after an affirmation of faith, and the Lord's Supper with footwashing, the "ordinance of humility", within the communion service.
The service is "open to all believing Christians", and most Adventists understand the Passover fruit of the vine as unfermented grape juice.
The Christian Church (Disciples of Christ) celebrates the Lord's Supper in weekly worship at a table open to all followers of Jesus Christ, and describes baptism as a choice made by the person.
For the Churches of Christ, which have no central body, one congregational voice holds that the immersion of a believer is necessary for forgiveness of sins.
Keeps no outward sacraments: Robert Barclay's Apology (1678) holds one inward baptism of the Spirit and an inward communion, and treats the outward rites as figures.
Britain Yearly Meeting holds that outward sacraments, however valid for others, "are not, in our experience, necessary for the operation of God's grace".
Does not practice baptism and the Eucharist "as such", sees "the whole of life as a sacrament" and holds that no external observance is essential to salvation.
Andrew Miller's doctoral thesis dates William Booth's abandoning of the practice of the sacraments to 1883. It keeps rites of its own, among them the Mercy Seat and the dedication of infants.
Cannot be given a single count, and many are largely paperless churches, so much of what is known of their rites comes from scholars' fieldwork.
Many give water a place wider than baptism, and Apostolic, Zionist, Ethiopian and Messianic churches regard river baptism as the real baptism. Some, such as the Harrist Church, keep baptism and Communion, while the African Church of the Holy Spirit baptizes in the Spirit and does not celebrate Holy Communion.
The Didache, the earliest church order on baptism in the sources, directs baptism in the threefold name in living water, or water poured thrice on the head, and admits only the baptized to the Eucharist. Its date is disputed, from 65 to 80 or before 100 to Harnack's 131 to 160, and Niederwimmer's publisher traces its origins to the first century.878889
The Fourth Lateran Council teaches that the bread and wine are "changed in substance, by God's power, into his body and blood", and requires the faithful to confess at least once a year and to receive the Eucharist at least at Easter.6
The Synod of Jerusalem, in the Confession of Dositheus, declares the Evangelical Mysteries to be seven and holds that "baptism is necessary even for infants".115
The Catholic and Oriental Orthodox dialogue issues The Sacraments in the Life of the Church at Rome: the Catholic Church recognizes the validity of all Oriental Orthodox baptisms, while "In certain contexts, the Coptic Orthodox Church practices rebaptism of Catholics."28
Describe each tradition from its own confessions, catechisms, canons, statements and official pages, and mark an outside account as such.
Name each rite in the words of the church that keeps it, since no word for the rites is neutral64118.
Give each biblical text in its own wording, with the version named, before setting out how each tradition reads it.
Attribute every claim about what a rite effects, and report a judgment that a rite is valid as the judgment of the church that makes it, on its own terms119.
Where sources disagree, give both readings with their sources, and choose between them only where one is plainly better attested.
Keep a commission's agreed statement apart from the teaching of the churches: ARCIC's Windsor Statement claimed substantial agreement on the Eucharist, while the Catholic Response of 1991 judged that it was not yet possible to say so120121.
Distinguish a church's custom from an exceptionless rule, as with the 40 and 80 day periods for baptism in the Coptic and Ethiopian churches2526.
Follow the teaching through its history in date order, report disputed dates with both sources, and mark plainly where a text could not be opened.

It depends on the church: the Catholic, Lutheran, Anglican, Reformed and Methodist churches speak of sacraments and the Eastern churches of holy mysteries, while Baptists, many Pentecostals, Adventists and Brethren speak of ordinances4345042521156677163. Each word carries a claim: "ordinance" stresses Christ's institution, and the Westminster Standards use it of the sacraments too6543. The Church: Towards a Common Vision (2013) suggests the difference may be one of emphasis160.
The Catholic Church defines seven, the Eastern Orthodox usually count seven without having fixed the number, and the Church of the East holds seven of a different content21230. Most Protestant churches count two, the Lutheran Apology allows Absolution as a third, several churches add footwashing, and the Friends and The Salvation Army keep no outward sacraments5033687779.
The traditions answer in different ways: the Catholic Church teaches a change of substance, the Orthodox a change by the Holy Spirit whose manner is not explained, Lutherans a sacramental union, the Reformed a spiritual feeding on Christ by faith, and the Baptist Faith and Message a symbolic act of obedience11315364257. Lutherans and Catholics "can together affirm the real presence of Jesus Christ in the Lord's Supper", in the words of From Conflict to Communion (2013), while The Church: Towards a Common Vision lists the presence of Christ among questions still open161160.
Largely, though not in every case: the Catholic Ecumenical Directory holds baptism by immersion or pouring with the Trinitarian formula valid of itself, and Catholics and Methodists give full recognition to each other's baptism162163. Eleven member churches of the German Council of Churches mutually recognized baptism on 29 April 2007164. Some churches require baptism of those baptized as infants, on the view that an infant's baptism is not a true baptism, and in 2020 the Catholic Church held invalid a baptism given with the words "We baptize"129165.
The Catholic Catechism teaches that God "has bound salvation to the sacrament of Baptism, but he himself is not bound by his sacraments", and the Confession of Dositheus calls baptism of the highest necessity166115. The Wisconsin Evangelical Lutheran Synod holds it ordinarily but not absolutely necessary, the Westminster Confession that grace is not inseparably annexed to it, and Southern Baptists make it a prerequisite to church membership, not a condition of salvation414257. The Friends and The Salvation Army hold that no outward observance is essential16778.
