The Seraphim are the highest order of angels. The word Seraphim i means "he who heals." Therefore, a Seraph literally means “a higher spirit who heals.” They are the angels of “divine fire, love and light.” They have the power to purify us with a lightening flash and flame. They hold the unveiled light of God and are the greatest illuminators. They are the most light-filled beings in creation.
They are the uppermost section of the hierarchy who are the closest to the Throne of God. They chant the Trisagion (ancient anthem), "Holy, holy, holy..." and encircle the Throne thereby existing through the love that is emanated by Creator God.
They are such wonderful angels to work with and if you're ever in a predicament and want to feel the pure Love of God through the angels, summon the Seraphim and they will come immediately
