Are you saying persons are not to be baptised anymore ?
Matthew 3:14-17King James Version (KJV)
14 But John forbad him, saying, I have need to be baptized of thee, and comest thou to me?
15 And Jesus answering said unto him, Suffer it to be so now: for thus it becometh us to fulfil all righteousness. Then he suffered him.
16 And Jesus, when he was baptized, went up straightway out of the water: and, lo, the heavens were opened unto him, and he saw the Spirit of God descending like a dove, and lighting upon him:
17 And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased.
I didn't mention baptism, but will now.
Back up to an earlier event, John doing his calling while Jesus was on His way to the river. What was the purpose of John's baptism?
John 1:29-34 (KJV)
[SUP]
29 [/SUP] The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.
[SUP]
30 [/SUP] This is he of whom I said, After me cometh a man which is preferred before me: for he was before me.
[SUP]31 [/SUP] And I knew him not: but that he should be made manifest to Israel, therefore am I come baptizing with water.
[SUP]
32 [/SUP] And John bare record, saying, I saw the Spirit descending from heaven like a dove, and it abode upon him.
[SUP]
33 [/SUP] And I knew him not: but he that sent me to baptize with water, the same said unto me, Upon whom thou shalt see the Spirit descending, and remaining on him, the same is he which baptizeth with the Holy Ghost.
[SUP]
34 [/SUP] And I saw, and bare record that this is the Son of God.
That baptism still has the same purpose, making Jesus manifest to all who witness that. Paul, an apostle didn't hold water baptism as a necessity of the gospel he preached. He manifested Jesus through the word of God and miracles. Some 1 years after Jesus arose from the dead Paul met some disciples of John Baptist. The men were carrying on after John, but needed to move up.
Acts 19:1-4 (KJV)
[SUP]1 [/SUP] And it came to pass, that, while Apollos was at Corinth, Paul having passed through the upper coasts came to Ephesus: and finding certain disciples,
[SUP]2 [/SUP] He said unto them, Have ye received the Holy Ghost since ye believed? And they said unto him, We have not so much as heard whether there be any Holy Ghost.
[SUP]3 [/SUP] And he said unto them, Unto what then were ye baptized? And they said, Unto John's baptism.
[SUP]4 [/SUP] Then said Paul, John verily baptized with the baptism of repentance, saying unto the people, that they should believe on him which should come after him, that is, on Christ Jesus.
Now I ask what that had to do with Moses and a requirement to keep those commandments instead of what Paul referred to? Again, I think you and a few others are mixing two covenants never meant to be mixed.
