The origin of the word dates back to an Assyrian word karabu, which were the servants of the gods of the various religions of that place and time. These emotionless servitors were visually much closer to the Sphinx of Egypt than modern child angels. These cherubs were included in the folk religions which eventually became what we now call Judaism, which had a well developed theology that assigned different classes of angels to different tasks in the supernatural world. Of these, the cherubim were considered the lowest class of angels, tasked with guardianship and protection of believers.Christianity incorporated both this hierarchy of angels, with seraphs at the peak, and cherubim just below them, and the various pagan religions which were its competitors. It was the image of the Roman god Cupid (and his Greek counterpart Eros) which was grafted on to the Assyrian and Semitic concepts of the cherub. The familiar winged child was developed in the early years of the Church to incorporate the beliefs and rituals of non-Christian religions into Christianity. Much as other pagan gods were turned into Saints, the Cupid/Cherub concept was fully enmeshed into Christian mythology. Cherubs immediately became one of the most popular classes of angels, both because of their non-threatening appearance and the positive reputation for helping believers and delivering good tidings.
