Whether peace is the proper effect of charity?

Objections

Objection 1 : It would seem that peace is not the proper effect of charity. For one cannot have charity without sanctifying grace. But some have peace who have not sanctifying grace, thus heathens sometimes have peace. Therefore peace is not the effect of charity.
Objection 2 : Further, if a certain thing is caused by charity, its contrary is not compatible with charity. But dissension, which is contrary to peace, is compatible with charity, for we find that even holy doctors, such as Jerome and Augustine, dissented in some of their opinions. We also read that Paul and Barnabas dissented from one another (Acts 15). Therefore it seems that peace is not the effect of charity.
Objection 3 : Further, the same thing is not the proper effect of different things. Now peace is the effect of justice, according to Is. 32:17: "And the work of justice shall be peace." Therefore it is not the effect of charity.
