“ Now it is evident to all that the silly successors of Noetus, and the champions of his heresy, even though they have not been hearers of the discourses of Heraclitus, nevertheless, at any rate when they adopt the opinions of Noetus, undisguisedly acknowledge these (Heraclitean) tenets. For they advance statements after this manner—that one and the same God is the Creator and Father of all things; and that when it pleased Him, He nevertheless appeared, (though invisible,) to just men of old. For when He is not seen He is invisible ”

“ The Heresy of Noetus of Heraclitean Origin; Noetus’ View of the Birth and Passion of Our Lord.
In this manner Heraclitus assigns to the visible an equality of position and honour with the invisible, as if what was visible and what was invisible were confessedly some one thing. For he says, “An obscure harmony is preferable to an obvious one;” and, “Whatsoever things are objects of vision, hearing, and intelligence,” that is, of the (corporeal) organs,—“these,” he says, “I pre-eminently honour,” not (on this occasion, though previously) , having pre-eminently honoured invisible things. ”

“ And, confessedly, he asserts that what is immortal is mortal, [4] and that what is mortal is immortal, in the following expressions: “Immortals are mortal, and mortals are immortal, that is, when the one derive life from death, and the other death from life.” ”
