The Seraphs or Seraphim, meaning the Burning Ones, are angelic beings associated with the prophet Isaiah's vision of God in the Temple when God called him to his prophetic ministry. They are described as having six wings, with two wings covering their faces, two covering their feet, and two used for flight. Their voices are also said to be powerful enough to fatally kill a mere human and shatter glass. It is said that before his fall from grace, Lucifer was once a Seraphim himself and a prince of the choir.

It is said that the Seraphim flew about the throne on which God was seated, singing His praises as they called special attention to God’s glory and majesty. These beings apparently also served as agents of purification.

Seraphim are known to defy the laws of the universe when commanded such as when one placed a hot coal against Isaiah's lips with the words, “See, this has touched your lips; your guilt is taken away and your sin atoned for." It did not burn him, but instead healed. Similar to the other types of holy angels, the seraphim are perfectly obedient to God. Similar to the Cherubim, the Seraphim are particularly focused on worshipping God.
