Does it matter what words are spoken when someone is baptized?

the apostles understood jesus command to baptize as doing it in his name. acts 2, 8, 10, 19. col 3.16 to 17. chrislandwer@yahoo.com

Sure are:

According to the Roman Ritual, at present in use, three questions are to be addressed to the person to be baptized, as follows: "Dost thou renounce Satan? and all his works? and all his pomps?" To each of these interrogation the person, or the sponsor in his name, replies: "I do renounce". The practice of demanding and making this formal renunciation seems to go back to the very beginnings of organized Christian worship.

n addition to the necessary word "baptize", or its equivalent, it is also obligatory to mention the separate Persons of the Holy Trinity. This is the command of Christ to His Disciples, and as the sacrament has its efficacy from Him Who instituted it, we can not omit anything that He has prescribed. Nothing is more certain than that this has been the general understanding and practice of the Church. Tertullian tells us (On Baptism 13): "The law of baptism (tingendi) has been imposed and the form prescribed: Go, teach the nations, baptizing them in the name of the Father and of the Son and of the Holy Ghost." St. Justin Martyr (First Apology 1) testifies to the practice in his time. St. Ambrose (On the Mysteries 4) declares: "Unless a person has been baptized in the name of the Father and of the Son and of the Holy Ghost, he can not obtain the remission of his sins," St. Cyprian (Epistle 72), rejecting the validity of baptism given in the name of Christ only, affirms that the naming of all the Persons of the Trinity was commanded by the Lord (in plena et adunata Trinitate). The same is declared by many other primitive writers, as St. Jerome (IV, in Matt.), Origen (De Principiis I.2), St. Athanasius (Against the Arians, Oration 4), St. Augustine (On Baptism 6.25). It is not, of course, absolutely necessary that the common names Father, Son, and Holy Ghost be used, provided the Persons be expressed by words that are equivalent or synonymous. But a distinct naming of the Divine Persons is required and the form: "I baptize thee in the name of the Holy Trinity", would be of more than doubtful validity.

Yes it does because told how to do it.

(Matthew 28:19) Go therefore and make disciples of people of all the nations, baptizing them in the name of the Father and of the Son and of the holy spirit,

As long as it's biblical...no,

But sometimes there are organizations that will add their own extras into the baptism.
