Matthew 28:19—often deemed the 'Great Commission'—serves as the climactic directive of Jesus to His followers following His resurrection. The command, 'Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost' (cf. https://www.biblegateway.com/passage/?search=Matthew+28%3A19&version=KJV), is laden with significance. Theologically, this verse is a primary proof-text for the doctrine of the Trinity. The Greek text uses the singular 'ὄνομα' (onoma, 'name'), not 'names,' revealing the unity of essence within the Godhead—Father (Πατήρ, Patēr), Son (Υἱός, Huios), and Holy Spirit (Ἅγιον Πνεῦμα, Hagion Pneuma). The joint mention affirms co-equality and co-eternity, countering modalistic or Unitarian approaches. By linking this formula with baptism—a rite of initiation and covenant sign—Jesus frames entry into the New Covenant (cf. Romans 6:3-4; Galatians 3:27) in deeply Trinitarian terms. This is not a mere formula, but an induction into the life of the triune God. As the context follows Christ's proclamation of 'all authority in heaven and on earth' (Matthew 28:18), the commission is given with full divine backing. The verse thus grounds Christian mission, ecclesiology, and soteriology, as baptism accompanies teaching and discipleship within Christ's global Kingdom. Echoing Genesis 12's call to bless 'all nations,' the Great Commission fulfills Old Testament hope (cf. Isaiah 49:6).
