Matthew 28:19

The present active participle indicates a continuous or simultaneous action with 'making disciples.' The Greek word 'baptizo' means 'to immerse' or 'to dip,' suggesting immersion as the original mode of baptism, although the text does not explicitly prescribe it as the only valid mode. The emphasis is on the identity and authority into which one is baptized, not on the mechanics.

The preposition 'eis' (into, in) with 'onoma' (name) does not denote a mere recitation of words, but a dedication, an identification with, or an entry into the sphere of authority and possession of the person or persons invoked. It is an act of consecration and belonging. The use of the singular 'ὄνομα' (name) for the three divine persons is crucial: it suggests a unity of essence, authority, and purpose, while the explicit mention of 'Father, Son, and Holy Spirit' with repeated definite articles ('τοῦ Πατρὸς καὶ τοῦ Υἱοῦ καὶ τοῦ Ἁγίου Πνεύματος') underscores the distinctness of the persons within that unity. It is not a 'name' referring to a single person who has three titles, but the 'name' (the authority, the being) of the triune God.

The explicit and coordinated mention of the three divine persons is the clearest formulation of the Trinity in the New Testament. The repetition of the definite article 'τοῦ' before each title ('τοῦ Πατρὸς', 'τοῦ Υἱοῦ', 'τοῦ Ἁγίου Πνεύματος') emphasizes the distinctness of each person, while the singular 'ὄνομα' maintains the unity of the Godhead. This is fundamental to orthodox Trinitarian doctrine, which affirms one God in three distinct but co-equal and co-eternal persons.

Patristic

The Church Fathers consistently interpreted Matthew 28:19 as an affirmation of Trinitarian doctrine and as the scriptural foundation of baptismal practice. Tertullian, in *Against Praxeas*, ch. 26 (PL 2, col. 190), argued that the command to baptize 'in the name of the Father, of the Son, and of the Holy Spirit' demonstrates the real distinction of persons within the one Godhead, thereby refuting the modalistic monarchianism of Praxeas. Basil the Great, in *On the Holy Spirit*, ch. 10 (PG 32, cols. 109-116), stressed that the tripartite baptismal formula constitutes the fullest confession of faith: baptism conferred in this name simultaneously confesses the distinctness of the hypostases and the unity of the divine nature. Athanasius, in his first *Letter to Serapion on the Holy Spirit*, §§ 28-30 (PG 26, cols. 593-596), and in the *Discourses Against the Arians*, Discourse II, chs. 41-43 (PG 26, cols. 232-237), appealed to this verse to defend the consubstantiality of the Son with the Father and the full divinity of the Spirit, rejecting all ontological subordination. The patristic reading converges in seeing Matthew 28:19 as the scriptural basis for Trinitarian baptism and the doctrine of one God subsisting in three co-equal and co-eternal persons.

Reformed

The Reformed tradition, following Calvin, interprets Matthew 28:19 as the institution of Christian baptism in the name of the Triune God. Emphasis is placed on Christ's authority in the Great Commission and the nature of baptism as a sign and seal of the covenant of grace, which introduces the believer into communion with the Father, Son, and Holy Spirit. The Trinitarian formula is seen as essential for the validity of the sacrament, reflecting the nature of God revealed in Scripture.

Interpretive tension: Tension within the Reformed system does not center on the Trinitarian formula, but on the application of baptism (infant vs. believer's baptism) and its relationship to regeneration. However, the validity of the Trinitarian formula as an expression of the Godhead is not a point of debate.

Arminian

The Arminian tradition, exemplified by Wesley, also holds a Trinitarian interpretation of Matthew 28:19. The verse is fundamental to the Great Commission and baptism as an act of obedience and a public sign of the believer's faith and repentance. The Trinitarian formula is seen as the correct expression of God's nature and the basis for the believer's identification with the saving God. Emphasis is placed on the human response of faith and God's prevenient grace that enables that response.

Interpretive tension: As in the Reformed tradition, Arminian tension does not lie in the Trinitarian formula of Matthew 28:19, but in the relationship between divine grace and human will in salvation and discipleship. The Trinitarian formula is universally accepted as the biblical expression of the Godhead.

Contemporary

In contemporary theology, Matthew 28:19 remains a pillar for the doctrine of the Trinity and mission. N.T. Wright sees it as the inauguration of the new covenant and the extension of God's kingdom through the church, with baptism as the initiation rite into this new reality. Contemporary discussion often focuses on the relationship between Matthew 28:19 and passages in Acts that mention baptism 'in the name of Jesus.' Most Trinitarian scholars view the Acts passages as a shorthand way of referring to Christian baptism (which implicitly includes the authority of the entire Trinity, especially the Son), or as an emphasis on Jesus' authority as the Messiah, without contradicting Matthew's explicit formula. Oneness Pentecostalism, however, interprets the Acts passages as the exclusive normative formula, arguing that 'Father, Son, and Holy Spirit' are titles of Jesus and that baptism must be 'only in the name of Jesus.'
