The Seraphim Choir is the highest and most magnificent of the nine accepted Angelic choirs. Without question they are the closest in all of heaven to the very throne of God, and their primary function is to circle the incomprehensibly beautiful throne in perpetual adoration of the Lord. This is a task that is not nearly as monotonous as it may seem to mortals, given the nature of the angels (who have perfect powers of concentration) and the delight that such an honour actually brings to the spirits.
The Seraphim are almost always identified with fire-not the burning, painful flames and heat of hell, but the healing flame of Love. They are literally living flames. The intensity of their adoration and pure Love of God pure out of them as a flawless reflection of the divine Love that emanates from the Lord. Like the rising sun, each angel radiates such light that even the other holy beings, the cherubim and the thrones, cannot look upon them.
Characteristics
According to Enoch, each Seraphim has six wings. In the Old Testament Book of Isaiah (6:1-3) he writes "...I saw the Lord sitting upon a throne, high and lifted up; and his train filled the temple. Above him stood the seraphim; each had six wings: with two he covered his face, and with two he covered his feet, and with two he flew." In the Book of Revelation (4:8) is another possible reference: "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!"
