144. We read that when Jesus was baptized the heavens opened and John saw the Holy Spirit coming down like a dove (Matthew 3:16; Mark 1:10; Luke 3:22; John 1:32-33). This happened because baptism means regeneration and purification, and so does a dove.

Surely anyone can see that that dove was not the Holy Spirit and that the Holy Spirit was not in the dove. In heaven doves appear quite often. Every time they appear, the angels know that they correspond to feelings and thoughts in other angels nearby about regeneration and purification. As soon as the angels go to those other angels and start a conversation on a different subject than the one being pondered when the doves appeared, the doves immediately vanish.

The situation is similar with many things the prophets saw. John, for example, saw a lamb on Mount Zion (Revelation 14:1 and elsewhere). Surely everyone realizes that the Lord was not that lamb and was not in that lamb. The lamb was instead a representation of the Lord's innocence. This highlights the error of those who deduce the existence of three persons in the Trinity from the dove seen above the Lord when he was baptized and the voice heard from heaven saying, "This is my beloved Son" [Matthew 3:16-17].

The Lord uses faith and goodwill to regenerate us. This is the meaning of John the Baptists saying, "I baptize you for repentance with water, but the one who is coming after me will baptize you with the Holy Spirit and with fire" (Matthew 3:11; Mark 1:8; Luke 3:16). Baptizing with the Holy Spirit and with fire means regenerating through the divine truth that is in faith and the divine goodness that is in goodwill. The following words of the Lord also mean the same thing: "Unless you have been born of water and spirit you cannot enter the kingdom of God" (John 3:5). "Water" in this passage, and elsewhere in the Word, means truth in our earthly or outer self, while "spirit" means truth connected with goodness in our spiritual or inner self.
