With this, I am going to step away from the discussion. I have plenty else to see to, and I do not count it a profitable use of my time to swat away silly suggestions that I have some kind of low view of the words of Scripture.Jesus is God. Jesus said to take the Gospel to the world, to make disciples, to baptize them. The Bible is His word, and when His ministers spoke and tied baptism to repentance, they were speaking on His behalf. Are you suggesting that the words of the Apostles recorded in Scripture can't be taken for requirements of God?
Finally, I would direct you to a study of the Greek grammar of Matthew 28:19-20. As I said before, you are operating on some faulty assumptions.
