20 These perspectives, which Populorum Progressio opens up, remain fundamental for giving breathing-space and direction to our commitment for the development of peoples. Moreover, Populorum Progressio repeatedly underlines the urgent need for reform , and in the face of great problems of injustice in the development of peoples, it calls for courageous action to be taken without delay. This urgency is also a consequence of charity in truth . It is Christ's charity that drives us on: “ caritas Christi urget nos ” (2 Cor 5:14). The urgency is inscribed not only in things, it is not derived solely from the rapid succession of events and problems, but also from the very matter that is at stake: the establishment of authentic fraternity. The importance of this goal is such as to demand our openness to understand it in depth and to mobilize ourselves at the level of the “heart”, so as to ensure that current economic and social processes evolve towards fully human outcomes.
