Why did Marcion introduce HULE into his Teaching?

And if Mani and Bardaisan have called the Maker God, perhaps a way might have come to them to call HULE also (God). For it is the cause of the Making as they say. As for Marcion who compelled him to rend again his tunic and dance with the wanton. . . .? For if he says concerning the Stranger that he is not the Maker this would be sufficient to put him in error. For he said that the Good One came—he who did not make (things)—and gave life to the Sons of the Maker; and because he had no property in the realm of the Creator it would not be necessary for him to undertake the cause of HULE. And if in order to show that the Maker tricked HULE the Stranger Himself did not keep faith with him when he came, and transferred by fasting and prayer the bodies which were from HULE, and after he worked all this work in them he sent them by death to the realm of HULE, he removed them without [P. 142.] compensating the Maker in that he raised the bodies of Enoch and Elijah to Heaven, and promised resurrection in his Scriptures [Dan. xii.13.] as He said to Daniel, 'Go, rest till the end, and thou shalt stand in thy time at the end of the days.' And who forced Marcion to introduce the subject of HULE except HULE herself, For she who is preached could not fail to make a revelation concerning her name by the mouth of her Preachers.
