The Bible very clearly talks of twelve various baptisms. They are as follows:
1.) Christ baptizing with the holy Spirit
(Mat.3:11; Acts 1:4-5; Acts 11:15-16)
2.) The holy Spirit baptizing into the Body of Christ
(Col.2:11-12; Rom.6:3-4; 1 Cor.12:13)
3.) Death Baptism
(Luke 12:50; Mat.20:22-23; Mark 10:38)
4.) Fire Baptism
(Mat.3:11; Luke 3:16)
5.) the typical baptism of Noah’s Ark
(1 Peter 3:13-21). Note that the occupants of the ark did not get wet.
6.) Baptism for the dead
(1 Corinthians 15:29). Note this is the verse Mormons use to support their view on baptism for the dead.
7.) Baptism unto Moses
(1 Cor. 10:2). Note again, these who were baptized "in the cloud and in the sea" went across on "dry ground" according to the Exodus account; their baptism was apart from water. This is obviously not a "water baptism" for Israel crossed the Red Sea on "dry ground" (Exodus 14:22). Pharaoh and his army, were the ones dipped into the water as it crashed down on them in divine judgment. However, it was Israel who was said to have been baptized. Hence, this was a dry baptism!
8.) Divers baptisms of the law
(Heb.9:10; John 1:25)
9.) Traditional Jewish baptisms (not part of the law, but became man made law)
(Mark 7:1-9)
10.) John’s baptism of Israel for the remission of sins
(Mat.3:6-16; Mark 1:4-9; Luke 3:3-21, John 1:23-28; etc.)
11.) Christ’s baptism by John to fulfill all righteousness
(Mat.3:14; etc.). Note, the Lord states it was necessary, not that it was for a testimony.
12.) Pentecostal baptism for the remission of sins
(Acts 2:38; etc.)
I think you missed a reference - or maybe oyu can tell me where oyu would place this reference to Baptism as it is clearly the one that most clearly tells us of the necessity of being baptized in order to properly accept the free gift of salvation.
John 3:5 Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
Personally I think #1, 2 and 12 are all the same and this verse goes along with them. Additionally other numbers could be combined as the TYPE from the Old Testament of the fulfillment under the New Covenant.
