"SERAPHIM of the FIRST SPHERE - CHRISTIAN HIERARCHY"

The Seraphim are closest to divinity. They are concerned with keeping divinity constant and intact, and are considered the angels of pure love, light and fire. They ensure that only positive energy reaches to divinity, and create positive energy through all the choirs of angels and into the physical realms. When you wish to raise energy for humanitarian or planetary causes ask for their help and guidance.

"It is not because angels are holier than men or devils that makes them angels, but because they do not expect holiness from one another, but from God alone.  ~William Blake"

The First Order or Choir in the first sphere are the Seraphim. Seraphim are the divine beings of purest love. They are said to have 6 wings. They also shine the brightest. Of all the angels, based on what I have researched, they are the holy ones that do not show their face and feet. As per the picture above, the one on the left symbolizes their burning passion towards God, while on the right implies how the wings are used. 

CI:

The Seraphim (singular "Seraph"), mentioned in Isaiah 6:1-7, were considered the highest order of the Hierarchy of Angels. Seraphim means "the fiery or burning ones" from the Hebrew root word "sarap" (fiery) and they are the angels of divine fire, love and light. They are the closest to God as they serve as the caretakers of God's throne and are continuously singing the "Trisagion" translating to "Holy, Holy, Holy".

It is said that there are four Seraphim surrounding God's throne, where they burn eternally from their love and zeal for God and that such a bright light emanate from them that nothing, not even other divine beings, can look upon them.

"Isaiah 6" in the Old Testament speaks of them as "having six wings; two covering the face, two covering the feet, and two were used for flying."

They are associated with the colour of white. Unlike other Seraphim who had six wings, Lucifer (the Fallen Angel) was featured to have twelve wings.
