There are many baptisms in the Bible.  There were divers washings under the law.  There was the baptism of John the baptist.  There was the baptism of Israel unto Moses in the Red Sea.  There was the baptism of the Holy Ghost.  There was the baptism with fire.  There was the baptism by the Spirit into the body of Christ.  Yet Paul says there is only one baptism for believers today.  Which one is it?
