Addressing the OP only.
the Baptism of Water is an ordinance, a command of God, true for repentance. water is only the mechanism use in this repentance. for John could had baptized "WITH" milk, or gasoline, or peanut oil ..ect. water was used to baptized here for repentance. as for the Lord who is Spiritual, he uses his Spirit to Baptize his chosen into his body, "the baptism "of" the Holy Spirit". and to empower his chosen believers, each has a gift which is given to them which is called the "Baptism "WITH" the Holy Spirit. as on the day of Pentecost, it was by the Spirit that the apostles that spoke in divers tongues, which is a "GIFT" of the Holy Ghost.
as said there are many Baptism, but the lord through his chosen apostle said this, Hebrews 6:1 "Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God,
Hebrews 6:2 "Of the doctrine of baptisms, and of laying on of hands, and of resurrection of the dead, and of eternal judgment.
Hebrews 6:3 "And this will we do, if God permit.
