The first cannon of the Bible reveals the names of only two Angels: Michael and Gabriel. Michael is the only Archangel described in the first canon (Daniel 10:13; Jude 9). Gabriel is thought to be an Archangel, but the Bible in its present iteration does not support the designation (Daniel 8:16, 9:21; Luke 1:19, 26). The 1611 version of the Bible includes the Apocrypha or the second cannon of the Bible, in which other Archangels are discussed, including the office of Gabriel.
In the book of Tobit, Raphael says to Tobias that He is one of Seven Archangels that stand before the Lord, Michael being one of them. A third Archangel in the Apocrypha is named Uriel, whose name means fire of God. Uriel’s name is the only name not mentioned in the Lutheran Bible. He is prominent with Anglican and Russian Orthodox Christians (2 Esdras; 4 Esdras, and in the Latin Vulgate). Gabriel is also referred to as an Archangel in the Apocrypha.
The Seven Archangels are also referred to as the Seven Spirits of God, in the disputed Apocryphal book of Enoch, where Michael is called the protector of Israel.
The "seven spirits of God" are mentioned in Revelation 1:4; 3:1; 4:5; and 5:6. The seven spirits of God are not specifically identified, so it’s impossible to be dogmatic. Revelation 1:4 mentions that the seven spirits are before God's throne. Revelation 3:1 indicates that Jesus the Christ "holds" the seven spirits of God. Revelation 4:5 links the seven spirits of God with seven burning lamps that are before God's throne. Revelation 5:6 identifies the seven spirits with the "seven eyes" of the Lamb and states that they are "sent out into all the earth."
There are at least three interpretations of the seven spirits of God. The first is that the seven spirits of God are symbolic of the Holy Spirit. The Bible, and especially the book of Revelation, uses the number 7 to refer to perfection and completion. If that is the meaning of the “seven” in the "seven spirits," then it is not referring to seven different spirits of God, but rather the perfect and complete Holy Spirit. The second view is that the seven spirits of God refer to seven angelic beings, the seraphim or the cherubim. This would fit with the numerous others angelic beings that are described in the book of Revelation (Revelation 4:6-9; 5:6-14; 19:4-5).
A third view is based on Isaiah 11, “And the spirit of the Lord shall rest upon him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and of the fear of the Lord;” Isaiah 11:2
This explains the seven spirits of God: (1) Spirit of the LORD, (2) Spirit of wisdom, (3) Spirit of understanding, (4) Spirit of counsel, (5) Spirit of might or power, (6) Spirit of knowledge, (7) Spirit of the fear of the Lord. The Bible doesn’t tell us specifically who/what the seven spirits are, but the first interpretation, that they are the Holy Spirit, is most likely.
