Your assertions were that Matthew must have been present at the baptism of Jesus, that he had been a disciple of John, and that he had been baptized into John's baptism.
You have given no "biblical evidence" that supports your theory. You are making assumptions based on Peter's requirement that the replacement for Judas must have been with them from the baptism of Jesus to His ressurection.
That is hardly irrefrutable, and is obviously contrary to the biblical record that shows Matthew at his tax collector's booth, in Capernaum, well into the ministry of Jesus. You have not addressed that contradiction at all, but simply continue to put forth your theory with no scriptural support.John 4:1-2 "
Therefore when the Lord knew that the Pharisees had heard that Jesus was making and baptizing more disicples than John (2) although Jesus Himself was not baptizing, but His disiciples were...."
Please show me where these verses say that the disiciples of Jesus were "baptizing with the baptism of John"? John, himself, clearly makes a distinction between his baptism and the baptism of Jesus.
Again, if the baptism of John and Christian baptism are the same, why would Apollos need more instruction when everything he was teaching was fine, except he only knew of the baptism of John?This is not "irrefrutable evidence" of your beliefs. This passage is a simple acknowledgement of the mission of John and the fulfillment of prophecy. The disciples are not mentioned at all. "all the people" is referring to the crowds that followed Jesus because of His miracles. The poor and underclass accepted John as a true prophet. The Pharisees and the Lawyers did not.
Are you claiming that these people constituted a church? That they were saved? These same crowds will be chanting "crucify, crucify" before it is over.You are presenting two choices, as if every single person in Judea must have made the choice between John's baptism and rejecting John's baptism. The passage is speaking of those present. "all the people" is referring to the crowds (certainly in the thousands, but no where near every single person in the area; which probably numbered into the hundreds of thousands, perhaps more than a million people).
And even if Matthew was baptized at some point, that doesn't address your larger problem of Matthew being in the tax collectors booth, in Capernaum, well into the ministry of Jesus. Even if I agreed that the Apostles had been baptized at some point during the ministry of Jesus (there is no evidence beyond Andrew and one other), that doesn't address your assertion that all the Apostles were present at the baptism of Jesus or that they had been baptized into John's baptism.I simple disagree with your assumptions based on these passages of scripture. I have given you biblical support for why I believe what I do.I'm not sure what "unbiblical practice" I am suppose to be justifying.I have made it a point in my life to conform by beliefs to the clear teachings of scripture. What you have given is not clearly taught in scripture, but various assumptions on your part that are clearly contrary to what scripture teaches. You have not answers for the questions, other than to say, "it must be so because of Luke 7, or John 4" when those passages do not directly support your theories.
If you can convince me by scripture, I'll change my mind. You haven't done that.
peace to you
