The higher orders [of angels] are presumed to be closer in their nature to God and to function in roles that serve God more directly than the lower orders, which tend to the administration of the physical universe and the service of humankind. Some orders are associated with particular divine qualities - Seraphim with Love, Cherubim with Wisdom, Thrones with Judgment.
