"The Church's love for the poor . . . Is a part of her constant tradition." This love is inspired by the Gospel of the Beatitudes, of the poverty of Jesus, and of his concern for the poor. Love for the poor is even one of the motives for the duty of working so as to "be able to give to those in need." It extends not only to material poverty but also to the many forms of cultural and religious poverty.
