“Peacemakers truly “make” peace; they build peace and friendship in society. To those who sow peace Jesus makes this magnificent promise: “They will be called children of God” (Mt 5:9). He told his disciples that, wherever they went, they were to say: “Peace to this house!” (Lk 10:5).
The word of God exhorts every believer to work for peace, “along with all who call upon the Lord with a pure heart” (cf. 2 Tim 2:22), for “the harvest of righteousness is sown in peace by those who make peace” (Jas 3:18).
And if there are times in our community when we question what ought to be done, “let us pursue what makes for peace” (Rom 14:19), for unity is preferable to conflict.” ( Is 1:17).
