But what does “with the Holy Spirit and with fire” mean? Call to mind that day, on which for the Apostles “there appeared disparate tongues like fire, and sat over each one of them” (Acts 2:3). That the baptism of John did not impart the Spirit and remission of sins is evident from the following [words of] Paul, [who] “found certain disciples, and said to them: received ye the Holy Spirit since ye have believed? They said to him: but furthermore whether it be of the Holy Spirit, we shall hear. He said to them: into what were ye baptized? They answered: into the baptism of John. Paul then said: John indeed baptized with the baptism of repentance”—repentance, but not remission of sins; for whom did he baptize? “Having proclaimed to the people, that they should believe in the One coming after him, namely, Christ Jesus… they were baptized in the Name of the Lord Jesus: and Paul laying his hands on them, the Holy Spirit came upon them” (Acts 19:1-6).
Do you see, how incomplete was the baptism of John? If the one were not incomplete, would then Paul have baptized them again, and placed his hands on them? Having performed also the second, he showed the superiority of the apostolic Baptism and that the baptism of John was far less than his. Thus, from this we recognize the difference of the baptisms.
