Whether use regards also the last end?

Objections

Objection 1 : It would seem that use can regard also the last end. For Augustine says (De Trin. x, 11): "Whoever enjoys, uses." But man enjoys the last end. Therefore he uses the last end.
Objection 2 : Further, "to use is to apply something to the purpose of the will" (De Trin. x, 11). But the last end, more than anything else, is the object of the will's application. Therefore it can be the object of use.
Objection 3 : Further, Hilary says (De Trin. ii) that "Eternity is in the Father, Likeness in the Image," i.e. in the Son, "Use in the Gift," i.e. in the Holy Ghost. But the Holy Ghost, since He is God, is the last end. Therefore the last end can be the object of use.
