Whether peace is the same as concord?

Objections

Objection 1 : It would seem that peace is the same as concord. For Augustine says (De Civ. Dei xix, 13): "Peace among men is well ordered concord." Now we are speaking here of no other peace than that of men. Therefore peace is the same as concord.
Objection 2 : Further, concord is union of wills. Now the nature of peace consists in such like union, for Dionysius says (Div. Nom. xi) that peace unites all, and makes them of one mind. Therefore peace is the same as concord.
Objection 3 : Further, things whose opposites are identical are themselves identical. Now the one same thing is opposed to concord and peace, viz. dissension; hence it is written (1 Cor. 16:33): "God is not the God of dissension but of peace." Therefore peace is the same as concord.
