The necessary words are "N., I baptize you In the name of - Father - Son - Holy Spirit - Amen.
The priest can make it work using any grammar he wants. It’s a Sacrament; not an incantation.
With all do respect, derision is not a virtue.

I realize such comments are in jest, and I take no
real offense. Nonetheless, I maintain my question is a legitimate one because it concerns the addition of words that
could change the meaning of what is spoken, not grammar. “In what way?” Well, I’m glad you asked!
For example, the words of Consecration are by no means incantatory, yet if the priest does not say them correctly (barring simple mispronunciations et al.) the Sacrament is invalid. Therefore, what form is minimally necessary for the valid administration of Baptism? What adaptations are tolerable, even if either reprehensible or just plain dumb?
My question stems from the theological significance of the form this priest used: if, by saying “in the name of the Father, in the name of the Son, and in the name of the Holy Spirit,” the priest has introduced a substantial change to the meaning of the words by separating the divine Nature (q.v. New Advent Encyclopedia, Form of Baptism), what does that do to the Sacrament?
The “sensus fidelium,” as it were, suggests that I have nothing to be concerned about - and I’m glad for that confidence.
Nevertheless, my question still stands. Is it correct to say that the manifestation of intention and purpose [of the act] (“I baptize you”), combined with the mention of the three Persons of the Trinity [of course in conjunction with the use of “living water” (either pouring or immersion)], no matter the intervening content, satisfies the necessary conditions for valid (but not necessarily licit) conferral of the Sacrament?
If the answer is yes, then one could argue that, “In the name of the Father, Son, and Holy Spirit, I baptize you,” is valid. Likewise, “I baptize you in the name of the FATHER, creator of all the living, his only SON, Jesus Christ our Lord, and the HOLY SPIRIT, the bond of their love,” can also be argued as valid, though highly illicit.
Baptism is not an incantation. Yet, if the form and matter are sufficiently wrong
Ecclesia Supplet doesn’t even apply. Thank you for your interest in my question.
