“I have baptized you
But he will baptize you
With the Holy Spirit.”
ἐγὼ ἐβάπτισα ὑμᾶς ὕδατι, αὐτὸς δὲ βαπτίσει ὑμᾶς Πνεύματι Ἁγίῳ.
Mark and Matthew, chapter 3:11, are very similar in their description of John the Baptist speaking about baptism. Mark said that John proclaimed that he was baptizing them with water (ἐγὼ ἐβάπτισα ὑμᾶς ὕδατι). However, the one to come would baptize them (αὐτὸς δὲ βαπτίσει ὑμᾶς) with or in the Holy Spirit (Πνεύματι Ἁγίῳ). Matthew added that the one to come would baptize with the Holy Spirit and fire (πυρί). Even though there is no mention of fire here in Mark, Luke, chapter 3:16, said that the one to come would baptize with the Holy Spirit and fire also. The role of the Holy Spirit seemed important. There was a clear difference between the baptism of John and that of the later Christians with or in the Holy Spirit, as if there was some doubt among the earlier followers of Jesus.
