The seven sacraments are Baptism, Confirmation or Chrismation, Eucharist, Reconciliation or Penance, Anointing of the Sick, Holy Orders, and Matrimony. Roman Catholic and Orthodox Christians understand these rites as encounters with divine grace, not simply ceremonies representing belief.
That answer is easy to memorize. The deeper IB task is explaining how ritual, doctrine, community, and religious experience meet within each sacrament. Knowing seven names produces a list. Connecting them to salvation, sacred texts, and denominational interpretation produces an argument.
This guide uses the framework of IB World Religions Christianity, including its fundamental questions and five themes. For wider context, begin with RevisionDojo’s IB World Religions Christianity introduction.

Catholicism formally defines seven sacraments and groups them by purpose. Orthodox Christianity generally recognizes the same seven but often describes the Church’s entire life as sacramental. Many Protestant traditions give special status to Baptism and the Lord’s Supper as rites instituted by Christ, although beliefs and practices vary.
Two students discover that memorizing seven names is shorter than explaining their meaning and context.
What does sacrament mean?
The English word comes through the Latin sacramentum, a term used in Western Christianity for a sacred sign or mystery. Catholic teaching describes a sacrament as an efficacious sign of grace, instituted by Christ and entrusted to the Church. “Efficacious” is important because the rite is understood to communicate what it signifies through God’s action.
Eastern Orthodox Christians more commonly call the sacraments Holy Mysteries, from Greek mystērion, meaning a divine mystery revealed and experienced without being exhausted by rational explanation. This does not make Orthodox rites vague or merely metaphorical. It emphasizes that participation in divine life cannot be reduced to a mechanism.
Both traditions therefore regard sacraments as more than public badges of membership. Catholic theology often defines their signs and effects precisely. Orthodox theology typically places greater emphasis on liturgical participation, transformation, and mystery.
The sacraments of initiation
Baptism
Baptism uses water with the Trinitarian formula commanded in Matthew 28:19. Romans 6:3-4 associates it with participation in Christ’s death and resurrection, while Acts 2:38 connects it with repentance, forgiveness, and the Holy Spirit.
Catholic and Orthodox churches baptize infants as well as adult converts. Both interpret Baptism as entry into the Church and new life in Christ. The visible washing communicates an invisible theological claim: human beings need cleansing, incorporation, and grace.
The normal sequence differs. In the Latin Catholic Church, an infant’s Confirmation and first Eucharist usually occur later. In Orthodox practice, Baptism is normally followed immediately by Chrismation and Eucharist, including for infants. Eastern Catholic churches also commonly preserve this unified pattern.
Confirmation and Chrismation
In Catholic terminology, Confirmation suggests strengthening. Orthodox Chrismation takes its name from the consecrated oil, called chrism or myron, used as the gift of the Holy Spirit is invoked.
Acts 8:14-17 describes baptized believers receiving the Holy Spirit through the laying on of apostolic hands. Catholic interpretation emphasizes strengthened baptismal grace and Christian witness. Orthodox interpretation frequently presents Chrismation as personal participation in Pentecost, received directly after Baptism.
Eucharist
Eucharist comes from the Greek word for thanksgiving. Its central texts include the Last Supper accounts and Paul’s description in 1 Corinthians 11:23-26.
Catholics teach that Christ is truly present and explain the change using transubstantiation: the substance of bread and wine becomes Christ’s body and blood while the observable properties remain. Orthodox Christians also affirm Christ’s real presence and a genuine change, but generally avoid treating one philosophical explanation as the complete measure of the mystery.
This is not a simple contrast between literal and symbolic belief. Both traditions understand the Eucharist as communion with the risen Christ, participation in his sacrifice, and an expression of ecclesial unity. RevisionDojo’s Christianity doctrine flashcards can help distinguish these related interpretations.
The sacraments of healing
Reconciliation or Penance
Catholic names include Reconciliation, Penance, and Confession. Orthodox Christians commonly speak of Confession or the Mystery of Repentance. The Greek term metanoia means a change of mind or direction, suggesting transformation rather than regret alone.
John 20:22-23 connects the disciples’ ministry with forgiveness, while James 5:16 instructs Christians to confess sins and pray for one another. In both traditions, the penitent acknowledges sin before a priest and receives absolution, although ritual forms vary.
The sacrament connects doctrine with ethics. Forgiveness does not remove moral responsibility. It seeks restored relationships with God, the Church, and other people, including practical amendment where possible.
Anointing of the Sick
James 5:14-15 describes church elders praying over sick people and anointing them with oil. Catholicism calls this Anointing of the Sick, while Orthodox Christianity often calls it Holy Unction.
The rite may include prayer for physical healing, but it does not guarantee a cure. It offers grace, forgiveness, courage, and spiritual strength during illness. Catholic teaching does not restrict it to the final moments of life; it may be received during serious illness or frailty. Orthodox practice similarly considers healing of the whole person, body and soul.
Sacraments of communion and vocation
Holy Orders
Holy Orders establishes ordained ministry through prayer and the laying on of hands. Relevant biblical passages include Acts 6:6, Acts 13:3, and 1 Timothy 4:14.
Catholicism recognizes bishops, priests, and deacons. Orthodox churches maintain the same threefold ministry through apostolic succession. Both reserve priestly and episcopal ordination to men, but rules concerning marriage differ. Latin Catholic priests are ordinarily celibate, with recognized exceptions. Orthodox churches may ordain married men as priests, while bishops are selected from celibate clergy.
Holy Orders demonstrates that religion is institutional as well as personal. Authority, continuity, pastoral care, teaching, and worship become visible within an ordered community.
Matrimony
Genesis 2:24, Mark 10:6-9, and Ephesians 5:21-33 are important texts for Christian reflection on marital unity and fidelity.
In Latin Catholic theology, baptized spouses confer the sacrament upon each other through consent witnessed by the Church. In Orthodox theology, the priestly blessing and crowning are central. The crowns can signify joy, responsibility, self-giving, and participation in God’s kingdom.
Both traditions treat marriage as a vocation shaped by faithful love, but they differ over marital breakdown and remarriage. Catholic teaching holds a valid sacramental marriage to be indissoluble; an annulment determines that a valid marriage was never established. Orthodox churches may permit a penitential second or third marriage in limited circumstances under episcopal authority.
Connecting the seven sacraments to the IB framework
The three fundamental questions turn description into analysis:
- What is the human condition? Humans are created for communion with God but experience sin, suffering, alienation, and mortality.
- Where are we going? The goal is salvation, resurrection, and participation in divine life. Orthodox theology often describes this as theosis, or union with God by grace.
- How do we get there? Faith, grace, worship, ethical transformation, and participation in the Church’s sacramental life shape the answer.
The five themes offer another analytical lens. Rituals make belief visible through water, oil, bread, wine, confession, and human promises. Sacred texts authorize and interpret those practices. Doctrines such as grace, salvation, real presence, and apostolic succession explain their meaning. Religious experience includes forgiveness, healing, belonging, and divine presence. Ethics appears in the responsibilities created by initiation, reconciliation, marriage, and ordination.

How to revise this topic effectively
Build a seven-row retrieval grid covering the name, sign, purpose, biblical text, Catholic emphasis, and Orthodox emphasis of each rite. Then practise paragraphs structured around a claim, evidence, interpretation, denominational comparison, and connection to an IB theme.
RevisionDojo is the ultimate IB resource for making that practice consistent. Use Study Notes for content, Flashcards for terminology, AI Chat for difficult distinctions, and the Questionbank for application. Grading tools reveal where an answer describes without analysing, while Predicted Papers and Mock Exams develop timed judgment. The Coursework Library and IB World Religions examples support research, while Tutors provide focused guidance. The IB World Religions mock exam guide offers a practical route from knowledge to written performance.
From a list to a religious worldview
The seven sacraments form a map of Christian life: birth into faith, spiritual strengthening, nourishment, forgiveness, healing, vocation, community, and hope. Catholic and Orthodox Christians share the central map while sometimes following different theological and liturgical routes.
That is the insight worth carrying into an IB response. Sacraments are not seven disconnected ceremonies. They show how material actions, sacred words, communities, and theological claims become inseparable. RevisionDojo’s connected resources can help you move beyond recalling the list and explain what these rites reveal about the human condition, salvation, and the Christian path between them.
