Probably those who embrace the views of Celsus will smile at us when we say, “At the name of Jesus every knee shall bow, of things in heaven, of things on earth, and of things under the earth, and every tongue” is brought to “confess that Jesus Christ is Lord, to the glory of God the Father.” But although they may ridicule such a statement, yet they will receive much more convincing arguments in support of it than Celsus brings in behalf of Chnoumen, Chnachoumen, Cnat, Sicat, and the rest of the Egyptian catalogue, whom he mentions as being called upon, and as healing the diseases of different parts of the human body.
And observe how, while seeking to turn us away from our faith in the God of all through Jesus Christ, he exhorts us for the welfare of our bodies to faith in six-and-thirty barbarous demons, whom the Egyptian magi alone call upon in some unknown way, and promise us in return great benefits. According to Celsus, then, it would be better for us now to give ourselves up to magic and sorcery than to embrace Christianity, and to put our faith in an innumerable multitude of demons than in the almighty, living, self-revealing God, who has manifested Himself by Him who by His great power has spread the true principles of holiness among all men throughout the world; yea, I may add without exaggeration, He has given this knowledge to all beings everywhere possessed of reason, and needing deliverance from the plague and corruption of sin.
