The Catechism of the Catholic Church (paragraph 233) says, Christians are baptized in the name of the Father and of the Son and of the Holy Spirit: not in their names, for there is only one God, the almighty Father, his only Son and the Holy Spirit: the Most Holy Trinity. The Trinitarian formula is so central to the Christian sacrament of baptism (Mt. 28:18-20), and thus of justifying the sinner (Acts 2:38), that the Church rejects all other formulas as invalid, that is, not accomplishing the purposes of Baptism. This includes “the baptism of John“ (Acts 18:25), baptism in the “name of Jesus” (mistaking the euphemism for being baptized into Christ as a formula), or, in our own day, baptism “in the Name of the Creator, Redeemer and Sanctifier.”
