I’m sure you are disappointment as you obviously feed on contention. Do you have a problem with the words of Jesus in Matthew 28:19? Do you believe that Romans 6:3-5 some how negates Matthew 28:19?
Matthew 28:19 isn't the only account of the great commission...
Luke 24:46 And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day:
[4] And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem.
[48] And ye are witnesses of these things.
[49] And, behold, I send the promise of my Father upon you: but tarry ye in the city of Jerusalem, until ye be endued with power from on high.
[50] And he led them out as far as to Bethany, and he lifted up his hands, and blessed them.
[51] And it came to pass, while he blessed them, he was parted from them, and carried up into heaven.
[52] And they worshipped him, and returned to Jerusalem with great joy:
They return to Jerusalem and are filled with the Holy Ghost, and when this is noised abroad this is what happens...
Acts 2:37 Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?
[38] Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
In fact, let me encourage you to do a word search for Father, Son, Holy Ghost and you will discover there is only one (1) hit - that is Matthew 28:18 ... Jesus was telling them what to DO, NOT what to REPEAT verbatim.
