And now, concerning His words: “And He
shall send His angels....” By “angels” is meant those who, reinforced by the
power of the spirit, have consumed, with the fire of the love of God, all human
traits and limitations, and have clothed themselves with the attributes of the
most exalted Beings and of the Cherubim.… And… inasmuch as these holy beings
have sanctified themselves from every human limitation, have become endowed
with the attributes of the spiritual, and have been adorned with the noble
traits of the blessed, they therefore have been designated as “angels.”
- Baha'u'llah (The Kitab-i-Iqan)
