Neither Matthew 28 nor Mark 16 can be interpreted as water baptism. It is gross error to make either of those baptisms to be water. The baptism that saves is always Holy Spirit baptism.
The Gospel is the Death, Burial, Resurrection of Jesus Christ. To believe the gospel we must believe all of it.
Peter knew this in Acts...
Acts 2:38 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.
1. Death = repent
2. Burial = water baptism in the name of Jesus Christ
for the remission of sins
3. Resurrection = Holy Spirit
Notice the above, we have both water and spirit (burial and resurrection).
Now then, you say that the water is not the water, lets look at other scriptures regarding water baptism with G907...
Matthew 3:6 And were baptized[SUP][SUB]G907[/SUB][/SUP] of him in Jordan, confessing their sins.
Matthew 3:13 Then cometh Jesus from Galilee to Jordan unto John, to be baptized[SUP]G907[/SUP] of him.
Matthew 3:16 And Jesus, when he was baptized[SUP]G907[/SUP], 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:
By-the-way you still have not answered newbirth...
so how do you Spirit baptise....since you say it is not water baptism...and it is something we must do ...how do we go around baptising people with the HS....???

19 [/SUP]Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
[SUP]16 [/SUP]He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
and if what you say is so ...why did Peter say...
[SUP]38 [/SUP]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.
[SUP]39 [/SUP]For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.
[SUP]40 [/SUP]And with many other words did he testify and exhort, saying, Save yourselves from this untoward generation.
[SUP]41 [/SUP]Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls.
With sincere hope that you come to the truth,
God bless!
