Baptism

"Go therefore and make disciples of all nations, baptizing them in the name (eis to onoma, into the name, into the ownership, into the identity) of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you" (Matthew 28:19-20). The Great Commission has one main verb: matheteusate (make disciples). The other verbs, going, baptizing, teaching, are the means and manner of the disciple-making.

The baptismal formula is Trinitarian: the single name (to onoma, singular, not plural) of the Father, Son, and Holy Spirit. The use of one "name" for three persons is itself a Trinitarian statement: the three are one in name, one in being.

The phrase "into the name" (eis to onoma) echoes commercial usage in the Greek world: a transfer into someone's name/account = a transfer of ownership. To be baptized into the name of the Trinity is to be transferred into the ownership and protection of the Triune God. The phrase appears in Acts as "in the name of Jesus Christ" (Acts 2:38; 10:48), the fuller Trinitarian formula and the short-form formula are not in contradiction; both point to the same reality of belonging to the God who is Father, Son, and Spirit.

"Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life" (Romans 6:3-4). Paul's argument in Romans 6 is that the believer's union with Christ in baptism makes the claim "let us continue in sin that grace may abound" (6:1) self-contradictory: the one baptized into Christ is baptized into his death and therefore is dead to sin.

The movement in verses 3-5 is: into his death (verse 3) → buried with him (verse 4a) → raised to walk in newness of life (verse 4b) → united with him in a resurrection like his (verse 5). Baptism does not save, Paul's argument in Romans 1-5 has established that salvation is by grace through faith. But baptism is the enacted sign of what is true: the one who has believed and been baptized has been joined to Christ in the death that breaks sin's power and the resurrection that gives new life.

The imagery favors immersion: burial implies going down and coming up, death-under-water and emergence into newness. The Greek word baptizo itself (to plunge, to immerse, to overwhelm, used in ancient sources for dyeing cloth by immersion) supports immersion as the mode, though the theological point is union with Christ, not the precise mechanics.

Acts 2:38: "And Peter said to them, 'Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.'" Peter's Pentecost call has four elements: (1) repent; (2) be baptized; (3) receive forgiveness; (4) receive the Holy Spirit. The sequence connects baptism to forgiveness and the Spirit, but the grammar does not require that baptism is the cause of forgiveness. Peter has already said "everyone who calls on the name of the Lord shall be saved" (2:21), and Cornelius receives the Spirit before baptism (10:44-48), demonstrating that the Spirit is not dependent on the baptismal rite.

1 Peter 3:21: "Baptism, which corresponds to this (the flood's water of judgment and salvation), now saves you, not as a removal of dirt from the body but as an appeal (eperotema, ἐπερώτημα, earnest appeal, pledge, request) to God for a good conscience, through the resurrection of Jesus Christ." Peter explicitly clarifies the sense in which baptism "saves": not by the water itself (not the removal of dirt from the body, a physical act) but as an appeal to God that engages the conscience and is grounded in the resurrection. Baptism is the outward appeal that corresponds to the inward faith.

Three major positions on baptism have developed within the Christian tradition:

(1) Credobaptism (believer's baptism, Baptist and evangelical tradition): baptism is the public declaration of a prior inward faith and belongs only to those who can profess that faith for themselves. The New Testament pattern appears to be hear-believe-be-baptized (Acts 2:41; 8:36-38; 10:44-48; 16:31-34). Immersion is the preferred mode. Infant baptism is rejected as having no clear New Testament precedent and as inverting the proper order of faith and sign.

(2) Paedobaptism (infant baptism, Reformed and Presbyterian tradition): baptism replaces circumcision as the sign of covenant membership (Colossians 2:11-12, "in him also you were circumcised with a circumcision made without hands... buried with him in baptism"). As circumcision was administered to the children of the covenant (Genesis 17) before they could express faith, so baptism is the new covenant sign administered to the children of covenant households. Household baptisms in Acts (16:15, 16:33, 1 Corinthians 1:16) may include infants, though this is disputed.

(3) Baptismal regeneration (Roman Catholic and some Lutheran tradition): baptism is not merely a sign but an instrument that effects what it signifies, the washing away of original sin and the infusion of new life. Titus 3:5 ("the washing of regeneration and renewing of the Holy Spirit") and John 3:5 ("born of water and the Spirit") are the key texts. Most Protestant interpreters hold that these refer to the Spirit's work (pictured as washing) rather than to the sacramental rite.

The Sanctum reads baptism as the enacted sign of union with Christ in death and resurrection, the public enactment of the new covenant belonging announced in the Great Commission, and the appeal to God for a good conscience that confirms the inward reality of repentance and faith. Whatever the position held on mode and subjects, the Sanctum's interest is in the theological weight the New Testament places on the rite: it is not an optional extra but the first outward act of the disciple.
