SERAPHIMA seraph (Hebrew שׂרף, plural שׂרפים Seraphim) is one of a class of celestial beings mentioned once in the Hebrew Bible (Tanakh or Old Testament), in Isaiah. Later Jewish imagery perceived them as having human form, and in that way they passed into the ranks of Christian angels. In the Christian Hierarchy of angels, seraphim represent the highest rank of angels.
Seraphim in the Book of Revelation
While there are no explicit references to seraphim in the New Testament, in the Book of Revelation (4:8) is a description clearly drawn from Isaiah:
"And the four living creatures, each of them with six wings, are full of eyes all around and within, and day and night they never cease to sing 'Holy, holy, holy, is the Lord God Almighty who was and is and is to come!".
Like the seraphim of Isaiah, these angels sing the Trisagion and bear six wings. If the first hearers of Revelation were intended to bring the Seraphim to mind in this description, then they are again identified with animals.
However, this citation could refer to the Ophanim/Thrones or the Cherubim, as there are indeed apparently 4 Cherubim that move along side the 4 Ophanim ("wheels") in Ez.10:17, which are sometimes described covered with eyes.
The Seraphim and the living creatures are often thought of in Medieval Christian theology as two separate ranks/types of angels although the six-winged entities singing "Holy, holy, holy", sometimes thought of as Seraphim, are also referred to as "living creatures". The descriptions of the Seraphim, Cherubim and Ophanim are often similar to the point of being confused, leading some, if not most modern theologians to suspect they are different designations of the same "living creature".

CHERUBIM
Cherubim in the Hebrew BibleDescriptions in the Bible vary, but in general all describe cherubim as winged creatures combining human and animal features. In the book of Genesis cherubim are described as guarding the way to the Tree of Life, east of the Garden of Eden armed with flaming swords (Genesis 3:24): "So he drove out the man; and he placed at the east of the garden of Eden cherubim, and a flaming sword which turned every way, to keep the way of the tree of life."
According to Exodus 26:1, cherubim were embroidered on the curtains of the tabernacle. In Solomon's Temple, two olivewood sculptures of cherubim plated with gold, ten cubits high, stood wingtip-to-wingtip guarding the Ark of the Covenant; in the tabernacle, two smaller cherubim sculpted from solid gold are described as standing on the cover of the Ark facing each other (Ex 25:18). The Ark of the Covenant stood in the Holy of Holies, where the shekhinah of God was said to reside; for this reason God is referred to in the Tanakh as "God who dwells between the cherubim".
The Cherubim in Solomon's Temple are described in 1 Kings 6:23-29 and 2 Chronicles 3:10-13.
THRONES
About the Thrones 
Thrones are angels of the Sixth Order and are beings of tremendous power and movement. They are the keepers of higher more expanded energies. They ensure that these energies maintain connections and flows through the realms. They are known as Thrones. They act as the conduits of the physical worlds and tend to be more stationary in their existence.
According to Pseudo-Dionysius the Areopagite
"The name of the most glorious and exalted Thrones denotes that which is exempt from and untainted by any base and earthly thing, and the super mundane ascent up the steep. For these have no part in that which is lowest, but dwell in fullest power, immovably and perfectly established in the Most High, and receive the Divine Immanence above all passion and matter, and manifest God, being attentively open to divine participations."
Known in scripture as the bringers of justice, but their status in hierarchy is often confused, sometimes placing them above the Seraphim, and sometimes placing them as the Cherubim. They do however, come in the second Choir, and are assigned to planets.
This position makes them some of the most powerful angels in service to the Lord. According to St. Thomas Aquinas, the Thrones have the task of pondering the disposition of divine judgments. In other words, they carry out or fulfill the divine justice of the Lord.
They create, channel and collect incoming and outgoing positive energies. Dispensation of justice is important to the Thrones and they send healing energies to victims while shining a light on injustice to bring it's presence to our attention.
Like their counterparts in the second angelic triad, they come the closest of all Angels to spiritual perfection and emanate the light of God with mirror-like goodness. They, despite their greatness, are intensely humble, an attribute that allows them to dispense justice with perfect objectivity and without fear of pride or ambition. Because they are living symbols of God's justice and authority, they are called Thrones and have as one of their symbols the throne.

Function and Philosophy of Ophanim
This group of Angelic Princes are often also called "Ophanim, Wheels or Galgallin." It is said that they were the actual wheels of the Lord's Heavenly Chariot (Merkabah). "The four wheels had rims and they had spokes, and their rims were full of eyes round about." They are also frequently referred to as "many-eyed ones."
God's spirit is conveyed in a certain manner to these angels, who in turn pass on the message to men and the inferior angels
