Blessed are the peacemakers is the 7th of the eight beatitudes that can be found in St. Matthew: Blessed are the poor in spirit: for theirs is the kingdom of heaven. Blessed are the meek: for they shall possess the land. Blessed are they who mourn: for they shall be comforted. Blessed are they that hunger and thirst after justice: for they shall have their fill. Blessed are the merciful: for they shall obtain mercy. Blessed are the clean of heart: for they shall see God. Blessed are the peacemakers: for they shall be called the children of God. Blessed are they that suffer persecution for justice's sake, for theirs is the kingdom of heaven. You can read more about Melanie Rigney's new book at Being Catholic ... Really .
