The Symposium (Banquet of the Ten Virgins)

The dragon, which is great, and red, and cunning, and manifold, and seven-headed, and horned, and draws down the third part of the stars, and stands ready to devour the child of the woman who is travailing, is the devil, who lies in wait to destroy the Christ-accepted mind of the baptized, and the image and clear features of the Word which had been brought forth in them. But he misses and fails of his prey, the regenerate being caught up on high to the throne of God—that is, the mind of those who are renovated is lifted up around the divine seat and the basis of truth against which there is no stumbling, being taught to look upon and regard the things which are there, so that it may not be deceived by the dragon weighing them down. For it is not allowed to him to destroy those whose thoughts and looks are upwards. And the stars, which the dragon touched with the end of his tail, and drew them down to earth, are the bodies of heresies; for we must say that the stars, which are dark, obscure, and falling, are the assemblies of the heterodox; since they, too, wish to be acquainted with the heavenly ones, and to have believed in Christ, and to have the seat of their soul in heaven, and to come near to the stars as children of light. But they are dragged down, being shaken out by the folds of the dragon, because they did not remain within the triangular forms of godliness, falling away from it with respect to an orthodox service. Whence also they are called the third part of the stars, as having gone astray with regard to one of the three Persons of the Trinity. As when they say, like Sabellios, that the Almighty Person of the Father Himself suffered; or as when they say, like Artemas, that the Person of the Son was born and manifested only in appearance; or when they contend, like the Ebionites, that the prophets spoke of the Person of the Spirit, of their own motion. For of Marcion and Valentinus, and those about Elkesaios and others, it is better not even to make mention.
