成唯識論述記 6.241

6.241

述曰：論主難云：應通三性，愛三境故。若許三性體應即欲，欲緣所樂故。若汝之信有其善、惡，惡不信可是有，於無記中其信是無，復非是欲。又信於三，信非三性，何妨愛三而唯性善，及為遮此妨作是言。又於四諦皆有信生，若愛樂是信，應於苦、集二諦信不緣之，誰有聖者愛樂苦、集故，苦、集諦應非信所緣。

The Commentary states: The author of the treatise raises an objection, saying: it would have to be common to the three natures, because one has fondness for objects of the three [natures]. If one grants that it is common to the three natures, its substance should be desire, because desire takes delight in what is cherished. If your faith has wholesome and unwholesome kinds, unwholesome lack of faith may indeed exist, but among indeterminate states, faith does not exist, nor is it desire. Furthermore, regarding faith directed toward the three [natures], faith is not of the three natures; why should fondness directed toward the three be solely wholesome in nature? To ward off this objection, this statement is made. Moreover, faith arises with respect to all four noble truths; if fondness and delight were faith, faith would not take the two truths of suffering and origination as its intentional object, for what noble one would have fondness and delight toward suffering and origination? Therefore, the truths of suffering and origination would not be intentional objects of faith.
