It is characteristic of the candour of Celsus that he lets slip a caution or two about the service of daemons. Christians are as credulous, he says in one place, as "those who lightly (_alogos_) believe in the roaming priests of Cybele (_metragurtais_) and wonder-seers, Mithras and Sabadios and the like--phantoms of Hecate or some other female daemon or daemons."[96] Again, he has a word of warning as to magic, and the danger and injury into which those fall who busy themselves with it--"One must be on one's guard, that one may not, by being occupied with these matters, become entangled in the service of them [literally; fused with them, _syntake_], and through love of the body and by turning away from better things be overcome by forgetfulness. For perhaps we should not disbelieve wise men, who say (as a matter of fact) that of the daemons who pervade the earth the greater part are entangled in 'becoming' (_genesei syntetekos_)--fused and riveted to it--and being bound to blood and smoke and chantings and other such things can do no more than heal the body and foretell future destiny to man and city; and the limits of their knowledge and power are those of human affairs."[97] [Sidenote: The rescue of the empire] At the last comes his great plea. Human authority is of divine ordinance. "To the Emperor all on earth is given; and whatever you receive in life is from him."[98] "We must not disbelieve one of old, who long ago said-- Let one be king, to whom the son of wise Kronos has given it.
