Sacred rites believed to convey God's grace; Catholics and Orthodox count seven, most Protestants two: baptism and the Lord's Supper.
See it on the Bible & Christianity map →What it is
A classic definition, traced to Augustine, calls a sacrament 'a visible sign of invisible grace'. Around 1150 Peter Lombard listed seven: baptism, confirmation, Eucharist, penance (confession), anointing of the sick, holy orders (ordination) and marriage. The Fourth Lateran Council (1215) required yearly confession and Easter communion, and used 'transubstantiation' for the bread and wine becoming Christ's body and blood. The Councils of Florence (1439) and Trent (1547) fixed the seven. Orthodox churches also count seven 'mysteries'.
Why it matters
They structured medieval life from birth to death and gave the clergy great authority. Disputes over them, especially communion, divided the Reformation churches from Rome and from each other.
Faith and history
The practices are documented from the New Testament onward (baptism in Acts 2:38; the Lord's Supper in 1 Corinthians 11). That they convey grace is a matter of faith.
Questions and debates
Catholics, Orthodox, Lutherans, Reformed and Baptists still differ on how Christ is present in communion and whether baptism saves or symbolizes.

▸Baptism of Jesus in the Jordan modeled the rite listed among The sacraments (baptism, Eucharist and the seven)Faith & scripture
The connection
The Gospels tell how John baptized Jesus in the Jordan, the Spirit descended and a voice called him 'my beloved Son' (Mark 1:9–11). Christians see it as the model for their own baptism, commanded in Matthew 28:19, which nearly all churches count as a sacrament (Baptists say 'ordinance').
When and where
The Jordan River, about AD 28, told in Mark 1, Matthew 3, Luke 3 and John 1. Ignatius (c. 110) wrote that Jesus' baptism purified the water.
How do we know?
Jesus' baptism by John is widely accepted as historical; its tie to Christian baptism is an interpretation of faith.
Questions and debates
John's baptism was for repentance, so why Jesus received it puzzled early Christians (Matthew 3:14). How John's rite relates to Christian baptism is debated.
▸The Last Supper is the origin of the Eucharist in The sacraments (baptism, Eucharist and the seven)Mostly agreed by scholars
The connection
At the Last Supper Jesus took bread and wine, saying 'this is my body... this is my blood' (Mark 14:22–24) and 'do this in remembrance of me' (Luke 22:19). Christians repeated the meal from the start, and it became the Eucharist, Mass or Lord's Supper, the central sacrament of most churches.
When and where
Jerusalem, about AD 30–33. Paul records the words around AD 54 (1 Corinthians 11:23–26); the Didache (c. 100) and Justin Martyr (c. 150) describe the rite.
How do we know?
Paul's letter is the earliest written record, and the meal's continuous practice is well attested. What it means is a matter of faith.
Questions and debates
Whether the meal was a Passover supper (Mark) or held the day before (John) is debated, as is what 'this is my body' means; Catholics, Orthodox, Lutherans and Reformed differ.
▸The sacraments (baptism, Eucharist and the seven) are held to convey Grace: salvation as God's free giftFaith & scripture
The connection
Catholic and Orthodox teaching holds that sacraments are channels of grace: God acts through the water, bread, wine, oil and words. Medieval theologians said they work by the rite itself (ex opere operato), not by the priest's holiness. Many Protestants see them as signs or seals of grace received by faith.
When and where
Augustine (c. 400) called them visible signs of sacred, invisible realities; Peter Lombard (c. 1150), Aquinas and the Council of Trent (1547) developed the teaching.
How do we know?
A matter of faith, not history. Church documents from Augustine through Trent and the Reformation confessions record what each tradition believes.
Questions and debates
How sacraments convey grace, and whether the recipient's faith is required, still divides Catholics, Orthodox, Lutherans, Reformed and Baptists.
▸Thomas Aquinas and the Summa Theologiae systematized, in his Summa, teaching on The sacraments (baptism, Eucharist and the seven)Historical record
The connection
In the third part of his Summa, Thomas explained the seven sacraments with Aristotle's ideas: each has 'matter' (water, bread) and 'form' (the words). He gave the classic account of transubstantiation: the bread's substance becomes Christ's body while its outward appearances remain. He also wrote hymns for the feast of Corpus Christi.
When and where
Paris and Naples, 1272–1273; the section broke off unfinished at penance, and his students completed it as the Supplement.
Historical evidence
The Summa survives; the Council of Florence's 1439 decree on the sacraments follows his wording, and Trent relied heavily on him.
Questions and debates
Whether Aristotle's categories are needed to explain the Eucharist is debated; Orthodox Christians affirm the change but decline to define how it happens.
▸Gothic cathedrals (Notre-Dame, Chartres) housed the celebration of The sacraments (baptism, Eucharist and the seven)Mostly agreed by scholars
The connection
A cathedral's whole design led the eye to the altar, where Mass (the Eucharist) was celebrated daily. Fonts held baptisms, side chapels held Masses for the dead, and the bishop performed confirmations and ordinations there. Relics drew pilgrims, adding more services and income.
When and where
Across medieval Europe from about 1140; Chartres, Notre-Dame and others held daily Masses and the bishop's ceremonies.
How do we know?
Liturgical books, cathedral statutes and the buildings' layout around the altar and choir show how they were used.
Questions and debates
How much ordinary worshippers saw of the service, often hidden behind a choir screen, and how they experienced it, is debated.
▸The sacraments (baptism, Eucharist and the seven) were defined as seven by Council of Trent and the Catholic ReformationHistorical record
The connection
Protestant reformers kept only two sacraments, baptism and the Lord's Supper, as instituted by Christ in Scripture. Trent declared there are exactly seven, all instituted by Christ: baptism, confirmation, Eucharist, penance, anointing of the sick, holy orders and marriage. It taught that they convey grace through the rite itself (ex opere operato) and affirmed transubstantiation (1551).
When and where
Trent's seventh session, March 3, 1547, defined the seven; later sessions covered the Eucharist and penance (1551), the Mass (1562) and marriage (1563).
Historical evidence
Trent's canons survive, each condemning a specific Protestant view; the number seven had already been listed by Peter Lombard (about 1150) and the Council of Florence (1439).
Questions and debates
The Orthodox also count seven 'mysteries' but never fixed the number so strictly; Anglicans and Lutherans differ on whether confession and other rites are sacraments.
▸Martin Luther kept only two (at first three) of The sacraments (baptism, Eucharist and the seven)Historical record
The connection
In The Babylonian Captivity of the Church (1520), Luther argued that a sacrament needs Christ's own command and a visible sign. That left baptism and the Lord's Supper; he first counted penance too, then dropped it. He kept Christ's real presence in communion but rejected transubstantiation and the Mass as a sacrifice.
When and where
Wittenberg, October 1520; his view of communion clashed with Zwingli's at the Marburg Colloquy, October 1529.
Historical evidence
Stated in Luther's own treatise and his Small and Large Catechisms (1529); the Council of Trent condemned these views in 1547.
Questions and debates
Lutherans still debate whether confession is a sacrament. Luther's Christ present 'in, with and under' the bread differs from both Catholic and Reformed views.
▸Second Vatican Council allowed local languages in The sacraments (baptism, Eucharist and the seven)Historical record
The connection
The council's first document, Sacrosanctum Concilium (1963), called for 'full, conscious, and active participation' and allowed local languages in the Mass and other sacraments. The rites of all seven were revised: Paul VI's Mass (1969–70), a new adult initiation rite (1972), and 'extreme unction' renamed anointing of the sick, for all the seriously ill.
When and where
Approved in St. Peter's Basilica on December 4, 1963, by 2,147 votes to 4; new rites introduced worldwide from 1964 into the 1970s.
Historical evidence
The constitution's text and vote record, and the revised liturgical books published by the Vatican.
Questions and debates
The text kept Latin and gave chant 'pride of place,' so whether the reforms went further than the bishops intended is debated, as is turning altars toward the people.
