51. From this point of view, if we recall that Jesus came to "preach the good news to the poor" (Mt 11:5; Lk 7:22), how can we fail to lay greater emphasis on the Church's preferential option for the poor and the outcast? Indeed, it has to be said that a commitment to justice and peace in a world like ours, marked by so many conflicts and intolerable social and economic inequalities, is a necessary condition for the preparation and celebration of the Jubilee. Thus, in the spirit of the Book of Leviticus (25:8-12), Christians will have to raise their voice on behalf of all the poor of the world, proposing the Jubilee as an appropriate time to give thought, among other things, to reducing substantially, if not cancelling outright, the international debt which seriously threatens the future of many nations. The Jubilee can also offer an opportunity for reflecting on other challenges of our time, such as the difficulties of dialogue between different cultures and the problems connected with respect for women's rights and the promotion of the family and marriage.
