6 Your statements about the sun himself are so false and absurd, that if he were to repay you for the injury done to him, he would scorch you to death. First of all, you call the sun a ship, so that you are not only astray worlds off, as the saying is, but adrift. Next, while every one sees that the sun is round, which is the form corresponding from its perfection to his position among the heavenly bodies, you maintain that he is triangular, that is, that his light shines on the earth through a triangular window in heaven.
Hence it is that you bend and bow your heads to the sun, while you worship not this visible sun, but some imaginary ship which you suppose to be shining through a triangular opening. Assuredly this ship would never have been heard of, if the words required for the composition of heretical fictions had to be paid for, like the wood required for the beams of a ship. All this is comparatively harmless, however ridiculous or pitiable. Very different is your wicked fancy about youths of both sexes proceeding from this ship, whose beauty excites eager desire in the princes and princesses of darkness; and so the members of your god are released from this humiliating confinement in the members of the race of darkness, by means of sinful passion and sensual appetite.
And to these filthy rags of yours you would unite the mystery of the Trinity; for you say that the Father dwells in a secret light, the power of the Son in the sun, and His wisdom in the moon, and the Holy Spirit in the air.
