Hi, Zenas.
The
Code of Canon Law for baptism does not detail the verbal form for validity but notes the requirements for the initiators, sponsors and officiants.
This section of the Catechism of the Catholic Church does specify the proper words and method of baptism. That should be official enough for you.
In short, any Christian faith that uses a similiar Trinitarian form of baptism ("In the name of the Father, and of the Son, and of the Holy Spirit) create a valid baptism in the eyes of the Church.
One important exception to the use of the Trinitarian formula: The Church of Jesus Christ of Latter-Day Saints, also known as the Mormons, have an invalid baptism.
While they use the proper words, their theology is, in effect, polytheistic (They believe that followers can become a god elsewhere after “exultation”, implying that God was once a man Himself). A Mormon convert to the faith is baptized again in the proper form, matter and intent.
