ah, but the Scriptures say there is only ONE baptism, not 2 or 3.
Oh, really?
There is the baptism of John. Acts 13:24 "When John had first preached before his coming the baptism of repentance to all the people of Israel."
There is the baptism of Jesus. Acts 19:4-5 "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. When they heard this, they were baptized in the name of the Lord Jesus."
Baptism of the Holy Ghost and fire. Matt. 3:11 "I indeed baptize you with water unto repentance. but he that cometh after me is mightier than I, whose shoes I am not worthy to bear: he shall baptize you with the Holy Ghost, and with fire"
There were also ritual baptisms in the Old Testament, the word "rachats" was used to mean wash, wash off, wash away, bathe and was used metaphorically to mean to wash the defilement of sin adhering to men. It was set as an ordinance forever for there to be a laver of bronze/brass to be put between the tabernacle and the altar for all the sons of Aaron (the priests) to wash before they made offerings to the Lord. Exodus 30:18-21 "18 “Make a bronze basin, with its bronze stand, for washing. Place it between the tent of meeting and the altar, and put water in it. 19 Aaron and his sons are to wash their hands and feet with water from it. 20 Whenever they enter the tent of meeting, they shall wash with water so that they will not die. Also, when they approach the altar to minister by presenting a food offering to the LORD, 21 they shall wash their hands and feet so that they will not die. This is to be a lasting ordinance for Aaron and his descendants for the generations to come.”
Offerings of animals were also ritually baptized (washed) before being offered. So, I hope you see that thinking baptize always and only means the water baptism "sacrament" is not correct.
