Whether a man ought to love more his benefactor than one he has benefited?

Objections

Objection 1 : It would seem that a man ought to love his benefactor more than one he has benefited. For Augustine says (De Catech. Rud. iv): "Nothing will incite another more to love you than that you love him first: for he must have a hard heart indeed, who not only refuses to love, but declines to return love already given." Now a man's benefactor forestalls him in the kindly deeds of charity. Therefore we ought to love our benefactors above all.
Objection 2 : Further, the more grievously we sin by ceasing to love a man or by working against him, the more ought we to love him. Now it is a more grievous sin to cease loving a benefactor or to work against him, than to cease loving one to whom one has hitherto done kindly actions. Therefore we ought to love our benefactors more than those to whom we are kind.
Objection 3 : Further, of all things lovable, God is to be loved most, and then one's father, as Jerome says [*Comment. in Ezechiel xliv, 25]. Now these are our greatest benefactors. Therefore a benefactor should be loved above all others.
