Seraphim Angels

Traditionally, Seraphim angels are believed to be celestial beings with two or three pairs of
wings who guard the throne of God. In christianity, seraphim angels are the highest ranking
in angel hierarchy. Seraphim angels are usually depicted as being red -- symbolizing fire.
Seraphim angels appear in the Old Testament as six-winged creatures who praise God.

The following Seraphim angel information is from the Catholic tradition:

"The name, a Hebrew masculine plural form, designates a special class of heavenly
attendants of Yahweh's court. In Holy Writ these angelic beings are distinctly mentioned only
in Isaiah's description of his call to the prophetical office (Isa., vi, 2 sqq.). In a vision of deep
spiritual import, granted him in the Temple, Isaiah beheld the invisible realities symbolized
by the outward forms of Yahweh's dwelling place, of its altar, its ministers, etc. While he
stood gazing before the priest's court, there arose before him an august vision of Yahweh
sitting on the throne of His glory. On each side of the throne stood mysterious guardians,
each supplied with six wings: two to bear them up, two veiling their faces, and two covering
their feet, now naked, as became priestly service in the presence of the Almighty. His
highest servants, they were there to minister to Him and proclaim His glory, each calling to
the other: "Holy, holy, holy, Yahweh of hosts; all the earth is full of His glory." These were
seraphim, one of which flew towards Isaiah bearing a live coal which he had taken from the
altar, and with which he touched and purified the Prophet's lips, that henceforth these might
be consecrated to the utterances of inspiration. Such, in substance, is Isaiah's symbolical
vision from which may be inferred all that Sacred Scripture discloses concerning the
seraphim. Although described under a human form, with faces, hands, and feet (Is., vi, 2, 6),
they are undoubtedly existing spiritual beings corresponding to their name, and not mere
symbolic representations as is often asserted by advanced Protestant scholars. Their
number is considerable, as they appear around the heavenly throne in a double choir and
the volume of their chorus is such that the sound shakes the foundations of the palace.
They are distinct from the cherubim who carry or veil God, and show the presence of His
glory in the earthly sanctuary, whilst the seraphim stand before God as ministering servants
in the heavenly court. Their name too, seraphim, distinguishes them from the cherubim,
although it is confessedly difficult to obtain from the single Scriptural passage wherein these
beings are mentioned a clear conception of its precise meaning. The name is oftentimes
derived from the Hebrew verb saraph ("to consume with fire"), and this etymology is very
probable because of its accordance with Isa., vi, 6, where one of the seraphim is
represented as carrying celestial fire from the altar to purify the Prophet's lips. Many
scholars prefer to derive it from the Hebrew noun saraph, "a fiery and flying serpent",
spoken of in Num., xxi, 6; Isa., xiv, 29, and the brazen image of which stood in the Temple in
Isaias's time (IV Kings, xviii, 4); but it is plain that no trace of such serpentine form appears
in Isaias's description of the seraphim. Still less probable are the views propounded of late
by certain critics and connecting the Biblical seraphim with the Babylonian Sharrapu, a
name for Nergal, the fire-god, or with the Egyptian griffins (séréf) which are placed at
Beni-Hassan as guardians of graves.
