Context

“, because the act of temperance requires both an act of reason, and an act of the concupiscible faculty, even as the act of faith requires an act of the will, and an act of the intellect. Reply Obj. 1: The truth is itself the good of the intellect, since it is its perfection: and consequently faith has a relation to some good in so far as it directs the intellect to the true. Furthermore, it has a relation to the good considered as the object of the will, inasmuch as it is formed by charity.” source
