ChatGPT summarized well known proofs for Mt 28:19. I didn't see anything Antichrist therein. Without any proof of an "antichrist spirit" I can't agree with you. It does make mistakes, but I didn't notice any in the quote I provided. Its correct to say the assessment of "Eusebius of Caesarea" is an opinion, one among many. PS: As a believer in providential preservation the scattered Eusebius quotes, which can be explained various, don't cause me to question the Trinitarian formula in Matthew 28:19
(a) Textual criticism.—In all extant MSS and versions the text is found in the traditional form, πορευθέντες οὖν μαθητεύσατε πάντα τὰ ἔθνη, βαπτίζοντες αὐτοὺς εἰς τὸ ὄνομα τοῦ πατρὸς καὶ τοῦ υἱοῦ καὶ τοῦ ἁγίου πνεύματος, διδάσκοντες αὐτοὺς τηρεῖν πάντα ὅσα ἐνετειλάμην ὑμῖν, though it must be remembered that the best manuscripts both of the African Old Latin and of the Old Syriac versions are defective at this point. The evidence of Patristic quotations is not so clear. It was formerly thought to be as unanimous as that of the MSS and Versions, but F. C. Conybeare (ZNTW, 1901, p. 275 ff.) has shown that this is not true, at least in the case of Eusebius of Cæsarea.

“And Jesus came, and spake unto them, saying, All power is given unto me in heaven and in earth. Goe ye therefore, and teach all nations, baptising them in the Name of the Father, and of the Son, and of the holy Ghost: Teaching them to observe all things, whatsoever I have commanded you: and lo, I am with you alway, even unto the end of the world. Amen.“ {Matthew 28:18-20}
In the book of Acts 2:38, the evangelist Luke described the same statement of Jesus from Matthew 28:19.20. But in Acts 1:8 Jesus calls us to proclaim His truth to all nations, without any mention of baptism in the name of the Trinity:
„But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto Me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.“ {Acts 1:8}
Scholars have identified that Eusebius quoted or referenced Matthew 28:19 approximately 18 times in his extant writings. Out of these, about 16 instances are cited without the Trinitarian formula, often ending with "in my name." in his works before Nicea here are a few:
“Surely none save our only Savior has done this, when, after His victory over death, he spoke the word to His followers, and fulfilled it by the event, saying to them, “Go ye and make disciples of all nations in My name.” {Eusebius: Oration in Praise of Emperor Constantine, Chapter 16, Section 8}
“But while the disciples of Jesus were most likely either saying thus, or thinking thus, the Master solved their difficulties, by the addition of one phrase, saying they should triumph “In MY NAME.” And the power of His name being so great, that the apostle says: “God has given Him a name which is above every name, that in the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth,” He shewed the virtue of the power in His Name concealed from the crowd when He said to His disciples: “Go, and make disciples of all the nations in My Name.” He also most accurately forecasts the future when He says: “for this gospel must first be preached to all the world, for a witness to all nations.” {Eusebius: Proof of the Gospel, Book III, ch. 7, 136 (a-d), p. 157}.
“Who said to them: ́Make disciples of all the nations in My Name. ́” {Eusebius: Proof of the Gospel, Book III, Chapter 7, 138 (c), p. 159}
“Relying upon the power of Christ, who had said to them, “Go ye and make disciples of all the nations in My name.” {Eusebius: Book III of his History, Chapter 5, Section 2, (about the Jewish persecution of early Christians)}
“With one word and voice, He said to His disciples: “Go, and make disciples of all nations in My Name, teaching them to observe all things whatsoever I have commanded you” {Eusebius: Proof of the Gospel, Book III, ch 6, 132 (a), p. 152}
Throughout the entire Bible, baptism is consistently described as being performed 'in the name of Jesus.' The true Bible does not provide conflicting sets of instructions, yet Matthew 28:19 seems to directly conflict with all other baptismal references. This discrepancy is strong evidence of potential falsification, as the two versions are fundamentally opposed and cannot coexist without contradiction. God never provides conflicting instructions!
“When they heard this, they were baptised in the Name of the Lord Jesus.“ {Acts 19:5}
“But when they believed Philip preaching the things concerning the kingdom of God, and the Name of Jesus Christ, they were baptised, both men and women. ́” {Acts 8:12}
“For as yet he was fallen upon none of them: only they were baptised in the Name of the Lord Jesus“. {Acts 8:16}
Below is the excerpt from Shem Tob’s MSS Hebrew Matthew Gospel, Matthew 28th chapter, which comes from a book by Dr. George Howard, a specialist in the Hebrew language. The original of this manuscript is in the Jewish Theological Seminary of America in New York. This Gospel was saved by Hebrews during the first century and was discovered in the 14th century. In the 14th century, there was no discussion of the Trinity! And in this old original manuscript of the Gospel, Matthew 28:19, there is no trinitarian form of baptism, there is no statement by Jesus in this regard. Matthew wrote his Gospel in Hebrew and not in Greek, as most theologians claim today:
“Matthew also issued a written Gospel among the Hebrews in their own dialect while Peter and Paul were preaching at Rome and laying the foundations of the church.” {Irenaeus in the second century: Adv. Haer. 3.1.1}
18. Jesus drew near to them and said to them: To Me has been given all power in heaven and earth.
19. Go
20. and (teach) them to carry out all the things which I have commanded you forever.
The same is also stated in the other 3 Bible translations:
“Then, coming toward them, Jesus spoke, saying, ‘All power has been given me in heaven and on earth. So, go and make disciples in all nations IN MY NAME, teaching them to obey all the things that I commanded you. And [Look!] I’ll be with you every day until the end of the age.“ {Matthew 28:18-20} Bible 2001
“Jesus approached and said to them, “All authority has been given to me in heaven and on earth. Consequently, when you go, disciple all nationalities IN MY NAME. Teach them to keep everything I commanded you to do. Understand this: I am with you every day until the consummation of the age!“ {Matthew 28:18-20} MIT – Idiomatic EN – 2006
“Yeshua [God is Salvation] drew near to them and said to them: “All power has been given to Me in heaven and earth”. “Go and make disciples, of all the nations, to believe IN MY NAME” “and teach them to observe all the words which I have commanded you, forever” {Matthew 28:18-20} New Messianic Version Bible
“The baptismal formula was changed from the name of Jesus Christ to the words Father, Son, and holy Spirit by the Catholic Church in the second century.“ {Britannica Encyclopedia, 11th Edition, Volume 3, page 365}
