Notice it says, in the name of the; name is singular. To be correct ,if indeed this verse is correct, should it not say, in the names, or if name is correct, In the name of the trinity, or in the name of God. We know the Holy Spirit is the spirit of the Father and not a member of a hypostatic union and so did Matthew . So is it, in the name of the Father, the son and the Father. Matthew was not a trinitarian and would never have written this verse in this way. The trinity says the three are distinct but not separate; the Father is not the son or the Holy Spirit. The truth is the Father and the Holy Spirit are not distinct as they are the same, the Father is the Holy Spirit. Jesus is a separate being from his God while the Holy Spirit is the Father the only true God. Genesis 6:3, Luke 2:35, 2 Corinthians 3:17. To make any truth sense to this verse it should be; in the names of the Father and the Son. Since we should have spiritual sense we should know that baptism is only in the name of Jesus which agrees with what the apostles did. If you can see, understand what I have written, then you should know Matthew 28:19 was indeed changed before the oldest writings of scripture that are in existence. If we had the original by the hand of Matthew we would see the truth but as it is we find the mistakes that were made by the changers because they do not agree with the truth.
