Jesus never verified what Paul wrote thus telling us that made up stories can be present in the Greek Gospel. And no 1st century Nazarenes testified that Paul was indeed chosen but rather the Nazarenes condemned Paul for spreading a false teaching. That is why all four 'canon Gospels' cannot be regarded as pure word of God as they were written by Romans that were misguided by Paul.
Paul-ine corpus was still a work-in-progress in the 2nd to 3rd century. And as can be seen from surviving manuscripts today, a complete Greek Gospel can only be found in 4th century A.D.
None of the early Roman Church Fathers ever quote Matthew 28:19 or 1John5:7 in their early days. However in the 4th century, the concept of 'three in oneness' were added to the original texts of Matthew 28:19 and 1John 5:7 thus showing how twisted were the minds of the Romans inventing lies as they progressively complete their Greek Gospel-Codex. We can also tell how Holy Spirit was not involved and never inspire the Romans in completing the Greek texts.
The verses below with 'supposed 3 added entities' were never quoted by early Roman fathers:-
Therefore go and make disciples of all nations, baptizing them in the name [MADE UP LIE] of the Father and of the Son and of the Holy Spirit [MADE UP LIE] (Matthew 28:19)
For there are three that beare record in heauen,[MADE UP LIE] the Father, the Word, and the holy Ghost: and these three are one. [MADE UP LIE] (1John 5:7)
For Christians apologist that still insist the Greek gospels as truth;
then it should be known that even Early Roman Church Fathers believed that there is only One Father the creator, creating all beings including God Son and Holy Spirit. This was the earliest belief for the Romans. Clearly, they do not belief in Triune concept as the three entities were never equally exist in oneness.
