21. This is what they say and other things like it in endless writings. And they persuade those who are their disciples to read the theory of Composition and Mixture[271] which is studied by many others and by Andronicus the Peripatetic. The Sethians then say that the theory about Composition and Mixture is to be framed after this fashion: The light ray from on high has been compounded and the [Sidenote: p. 221.] very small spark has been lightly mingled[272] in the dark waters below, and (these two) have united and exist in one mass as one odour (results) from the many kinds of incense on the fire. And the expert who has as his test an acute sense of smell ought to delicately distinguish from the sole smell of the incense the different kinds of it set on the fire; as (for example) if it be storax and myrrh and frankincense or if anything else be mixed with it. And they make use of other comparisons, as when they say that if brass has been mixed with gold, a certain process[273] has been discovered which separates the gold from the brass. And in like manner if tin or brass or anything of the same kind be found mixed with silver, these by some better process of alloy are also separated. But even now any one distinguishes water mixed with wine. Thus, he says, if all things are mingled together they are distinguished. And truly, he says, learn from the animals. For when the animal is dead each (of its parts) is separated (from the rest) and thus when dissolved, the animal disappears. This he says is the saying: “I come not to bring peace upon the earth but a sword”[274]--that is to cut in twain and separate the things [Sidenote: p. 222.] which have been compounded together. For each of the compounds is cut in twain and separated when it lights on its proper place. For as there is one place of composition for all the animals, so there has been set up one place of dissolution, which no man knoweth, he says, save only we who are born again, spiritual not fleshly, whose citizenship is in the heavens above. With these insinuations they corrupt their hearers, both when they misuse words, turning good sayings into bad as they wish, and when they conceal their own iniquity by what comparisons they choose. All things then, he says, which are compounds have their own peculiar place and run towards their own kindred things as the iron to the magnet, the straw to the amber, and the gold to the sea-hawk’s spine.[275] And thus the (ray) of light which was mingled with the water having received from teaching and learning (the knowledge of) its own proper place hastens to the Word come from on high in slave-like form and becomes with the Word a Word where the Word is, more (quickly) than the iron (flies) to the magnet.
