Whether we ought to do good to those rather who are more closely united to us?

Objections

Objection 1 : It would seem that we are nor bound to do good to those rather who are more closely united to us. For it is written (Lk. 14:12): "When thou makest a dinner or a supper, call not thy friends, nor thy brethren, nor thy kinsmen." Now these are the most closely united to us. Therefore we are not bound to do good to those rather who are more closely united to us, but preferably to strangers and to those who are in want: hence the text goes on: "But, when thou makest a feast, call the poor, the maimed," etc.
Objection 2 : Further, to help another in the battle is an act of very great goodness. But a soldier on the battlefield is bound to help a fellow-soldier who is a stranger rather than a kinsman who is a foe. Therefore in doing acts of kindness we are not bound to give the preference to those who are most closely united to us.
Objection 3 : Further, we should pay what is due before conferring gratuitous favors. But it is a man's duty to be good to those who have been good to him. Therefore we ought to do good to our benefactors rather than to those who are closely united to us.
Objection 4 : Further, a man ought to love his parents more than his children, as stated above (Question [26], Article [9]). Yet a man ought to be more beneficent to his children, since "neither ought the children to lay up for the parents," according to 2 Cor. 12:14. Therefore we are not bound to be more beneficent to those who are more closely united to us.
