Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 5
Blessed are the peacemakers: for they shall be called the children of God.
The peacemakers with others are not only those who reconcile enemies, but those who unmindful of wrongs cultivate peace. That peace only is blessed which is lodged in the heart, and does not consist only in words. And they who love peace, they are the sons of peace.
