Acts 2:38-39

Apostolic (Oneness) PentecostalThis is the new-birth promise at the heart of the apostolic faith. Peter, holding the keys of the kingdom, answers 'what shall we do?': repent, be baptized in the name of Jesus Christ for the remission of sins, and receive the gift of the Holy Ghost — the new birth of water and Spirit (John 3:5). Baptism is in the one saving Name (Acts 4:12), the Name of Father, Son, and Holy Ghost (Matt. 28:19) revealed as Jesus. 'The promise is unto you, and to your children, and to all that are afar off' — for every generation.

JewishPeter, a Jew addressing Jews at Pentecost (Shavuot), calls for repentance (teshuvah) and immersion akin to mikveh practice; the 'gift of the Spirit' echoes Joel. Read of Jewish renewal, not a baptismal formula.

CatholicA foundational baptismal text — repentance, baptism for the forgiveness of sins, and the gift of the Spirit; read with the Trinitarian formula of Matthew 28:19 (cf. the Catechism).

ProtestantThe apostolic call to repent and be baptized; traditions differ on baptism's relation to remission (sacramental vs. symbolic) and on the baptismal name, most using the Matthew 28:19 wording.

AcademicLuke's Pentecost speech reflects baptism 'in the name of Jesus' (also Acts 8:16; 10:48; 19:5); scholars note this Christ-name formula appears earlier than the triadic formula and debate their relationship.
