“He will baptize you
With the Holy Spirit
αὐτὸς ὑμᾶς βαπτίσει ἐν Πνεύματι Ἁγίῳ καὶ πυρί
This is similar to Matthew, chapter 3:11, Mark, chapter 1:8, and John, chapter 1:33. Luke indicated that John said that this mightier one to come was going to baptize them with the Holy Spirit (αὐτὸς ὑμᾶς βαπτίσει ἐν Πνεύματι Ἁγίῳ) and fire (καὶ πυρί). Matthew and Luke, mentioned fire with the Holy Spirit, but Mark did not. The role of the Holy Spirit seemed important because he was going to use purifying fire in the baptismal washing. There was a clear difference between the baptism of John with water for repentance and that of the later Christians with or in the Holy Spirit. Perhaps there was some doubt among the early followers of Jesus about the role of baptism.
