Sacraments
The Origin of the Term
The word "sacrament" does not appear in the Bible. It comes from the Latin sacramentum, which originally referred to a soldier's oath of allegiance or a sum of money deposited in a legal dispute. The early Latin translations of the Bible used sacramentum to translate the Greek word mysterion, "mystery" (Ephesians 5:32; 1 Timothy 3:16), and over time the term was adopted to describe sacred rites of the church.
Tertullian, writing around 200 AD, was the first to use sacramentum as a technical term for baptism and the Lord's Supper. The connection was natural: just as a Roman soldier swore a sacred oath when enlisting, the Christian made a sacred commitment in baptism. And just as a mystery involved a hidden reality made known to initiates, the sacraments involved a visible sign conveying an invisible grace.
The number and definition of sacraments have been debated throughout church history. Augustine defined a sacrament as "the visible form of an invisible grace." The Roman Catholic and Eastern Orthodox traditions recognize seven sacraments, while most Protestant traditions recognize only two, baptism and the Lord's Supper, as directly instituted by Christ.
Baptism: Dying and Rising with Christ
Baptism is the rite of initiation into the Christian community, commanded by Jesus in the Great Commission: "Go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit" (Matthew 28:19). The practice is rooted in Jewish ritual washing and the baptism of John, but Christian baptism carries distinctive meaning.
The book of Acts records baptism as the immediate response to faith in the gospel. On the Day of Pentecost, Peter called the crowd to "repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins" (Acts 2:38). The Ethiopian eunuch, the household of Cornelius, Lydia, and the Philippian jailer were all baptized upon believing (Acts 8:36-38; 10:47-48; 16:14-15, 33).
Paul developed the theological meaning of baptism most fully. He described it as union with Christ in His death and resurrection: "We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life" (Romans 6:3-4). Baptism signifies the believer's identification with Christ, the washing away of sin (Acts 22:16; Titus 3:5), the gift of the Holy Spirit (Acts 2:38), and incorporation into the body of Christ (1 Corinthians 12:13; Galatians 3:27-28).
The Lord's Supper: Remembering and Proclaiming
The Lord's Supper, also called Communion or the Eucharist, was instituted by Jesus on the night before His crucifixion. During the Passover meal, He took bread, gave thanks, broke it, and said, "This is my body given for you; do this in remembrance of me." After supper, He took the cup, saying, "This cup is the new covenant in my blood, which is poured out for you" (Luke 22:19-20; cf. Matthew 26:26-28; Mark 14:22-24; 1 Corinthians 11:23-26).
Paul transmitted this tradition to the Corinthian church, emphasizing that the Supper proclaims the Lord's death until He comes (1 Corinthians 11:26). It is a participation in the body and blood of Christ (1 Corinthians 10:16), a communal act that binds believers together as one body (1 Corinthians 10:17). Paul warned against partaking in an unworthy manner, treating the sacred meal with casual disregard, which he said had resulted in weakness, sickness, and even death among the Corinthians (1 Corinthians 11:27-30).
The precise nature of Christ's presence in the bread and wine has been the subject of intense theological debate. Roman Catholics teach transubstantiation, that the bread and wine become the actual body and blood of Christ. Lutherans affirm a real presence "in, with, and under" the elements. Reformed and Presbyterian traditions teach a spiritual presence received by faith. Baptists and many evangelicals understand the Supper as a memorial, an act of remembrance and proclamation. All agree that the Lord's Supper is a sacred act of worship commanded by Christ.
Old Testament Roots
While the sacraments are New Testament institutions, their roots extend deep into the Old Testament. Circumcision was the sign of the Abrahamic covenant (Genesis 17:10-14), and Paul drew a direct parallel between circumcision and baptism (Colossians 2:11-12). The Passover meal commemorated Israel's deliverance from Egypt and involved the sacrifice of a lamb, the sprinkling of blood, and a communal meal (Exodus 12:1-14), all of which find fulfillment in the Lord's Supper. Paul explicitly connected the two: "Christ, our Passover lamb, has been sacrificed" (1 Corinthians 5:7).
The sacrificial system, the ritual washings, the covenant meals, and the pouring of anointing oil all established the biblical principle that God uses physical means to convey spiritual reality. The sacraments continue this pattern, affirming that God meets His people not only in spiritual abstraction but through tangible, embodied experience.
The Sacraments and the Life of the Church
From the earliest days, the Christian community practiced both baptism and the Lord's Supper as central acts of worship. The book of Acts describes the first believers as devoted to "the apostles' teaching and to fellowship, to the breaking of bread and to prayer" (Acts 2:42). The "breaking of bread" almost certainly refers to the Lord's Supper, celebrated in the context of communal meals.
The Didache, an early Christian manual probably dating to the late first or early second century, provides the oldest non-biblical instructions for baptism and the Eucharist, confirming the centrality of these practices from the beginning. Justin Martyr, writing around 150 AD, described a Sunday worship service that included reading Scripture, preaching, prayer, and the celebration of the Eucharist, a pattern recognizable in Christian worship to this day.
The sacraments serve as tangible reminders that the Christian faith is not merely a set of ideas but an embodied reality. In baptism, believers publicly identify with Christ's death and resurrection. In the Lord's Supper, they continually remember His sacrifice and anticipate His return. Together, these sacred rites bind Christians to Christ and to one another in a community of grace.
Biblical Context
Baptism is commanded in Matthew 28:19 and practiced throughout Acts (2:38; 8:36-38; 10:47-48; 16:33). Paul's theology of baptism appears in Romans 6:3-4, 1 Corinthians 12:13, Galatians 3:27-28, and Colossians 2:11-12. The Lord's Supper is instituted in the Synoptic Gospels (Matthew 26:26-28; Mark 14:22-24; Luke 22:19-20) and taught by Paul in 1 Corinthians 10:16-17 and 11:23-30. Old Testament precedents include circumcision (Genesis 17:10-14) and Passover (Exodus 12:1-14).
Theological Significance
The sacraments embody the core of the gospel in physical form. Baptism enacts the believer's death to sin and resurrection to new life in Christ. The Lord's Supper continually proclaims Christ's atoning death and sustains the community in anticipation of His return. Both rites affirm that God works through material means to communicate spiritual grace, honoring the goodness of creation and the incarnation of Christ. They are acts of obedience, worship, and communal identity that have united Christians across centuries and traditions.
Historical Background
The practice of ritual washing was widespread in the ancient world, from Jewish mikveh baths to Greco-Roman mystery cult initiations. The Lord's Supper has roots in Jewish Passover and communal meal traditions. The Didache (c. 90-100 AD) provides early instructions for both sacraments. The theological understanding of the sacraments developed significantly through the writings of Augustine, the medieval schoolmen, and the Reformers. The Fourth Lateran Council (1215) defined transubstantiation. The Reformation debates between Luther, Zwingli, and Calvin over the nature of Christ's presence in the Supper remain one of the defining divisions in Protestant Christianity.
