Holy Spirit and archangel Michael were Ashshur- Vohuman (Spanta Minu) and Gabriel was archangel Mithra

The correspondence between Vohuman (Spanta Minu) and Ashshur with the Holy Spirit:

In Zoroastrianism, Vohuman (Bahman, good spirit, Spanta Minu) as the laughing Amshaspand and the bearer of the symbol of the dove corresponds to Ashshur ("heavenly sprit, smiling") and the Holy Spirit, with the symbols of fravahar and the dove. It is not without reason that in the Shahnameh, Nineveh and the City of Ashur are mentioned under the name of Bahman's Fortress.

The name Ahura Mazda (Asura Mazda) itself, in the form of Ahura Madhda, means the god of joy and happiness, and is related to the smiling attribute of Amshaspand Vohuman:

असुर m. asura supreme spirit

Iranians Sorush (hearing) corresponds to Ismail (hearing of God, Nabu) and Nairyusang (brave young messenger) corresponds to the god Mithra, the mediator.

Archangel Mithra is original of Bible's Gabriel

Mithra evolved into the patron divinity of friendship, and because his name means “(spiritual) friend”, "associate" abhors all violence, even he is sacred mediator and God of the Covenant.

Many have held the opinion that Mithra came originally from the high plateuas of the Hindukush, and the differences in his nature, when he is found later in India and Iran, were due to environmental influences in the two distinctly different areas. In the Vedas he was associated with Varuna and was invoked together with him as a light god. The Iranians, however, placed Mithra in the position of Archangel. Although Ahura Mazda was the supreme god, he created Mithra equal to himself and made him chief among the yazatas. Evidence of his exalted position lies in the fact that the longest yasht, eight times longer than that in honour of Ahura Mazda, is dedicated to Mithra.

The Holy Spirit, otherwise known as the Holy Ghost, is a concept within the Abrahamic religions. In Judaism, the Holy Spirit is understood as the divine quality or force of God manifesting in the world, particularly in acts of prophecy, creation and guidance. In Nicene Christianity, this conception expanded in meaning to represent the third person of the Trinity, co-equal and co-eternal with God the Father and God the Son.

In Islam, the Holy Spirit is a created spirit, sometimes seen as an angel or the angel Jibril/Gabriel (the strong of god, Mithra). The Spirit gives life to man.

The Jews in Medina objected to Muhammad that the closest angel to God was Michael (Vohuman), not Gabriel (Mithra). However, Michael could also be the same God of the covenant (Mithra, Gabriel) in the form of Mithael or Mithaqeel (God of the Covenant).

Spanta Mino (Holy Spirit) in the Avesta is Ahura Mazda himself, but Vohuman is the advisor and messenger och mediator of Ahura Mazda. John asserts, “God is love” [“(spiritual) friend”] (1 John 4:8). And so he is. God is all love and there is no shadow of evil in him. His nature can be defined as love for that is what he is. Some Christians feel the need to place an adjective like holy before the word love, so that they can say that God has a holy love. But this represents a misunderstanding of simplicity—that doctrine upon which Trinitarian theology stands and ensures that we can state without a second thought that “God is love.”

About Michael (Vohuman):

Michael, also called Saint Michael the Archangel, Archangel Michael and Saint Michael the Taxiarch is an archangel in Christianity, Judaism, Islam. He is the warrior of God. The earliest surviving mentions of his name are in third- and second-century BC Jewish works, often but not always apocalyptic, where he is the chief of the angels and archangels, and he is the guardian prince of Israel and is responsible for the care of the people of Israel. Christianity conserved nearly all the Jewish traditions concerning him, and he is mentioned explicitly in Revelation 12:7–12, where he does battle with Satan.
