2 But now We want to give you a new proof of Our regard for you, something We have wanted to do for a long time. Since the time of the solemn celebration of the fourth centenary of the discovery of America, We have diligently sought a way to provide for the common interests of Latin America which comprises more than half of the New World. And We foresaw that this could best be done if all you bishops from these regions came together for consultation at Our invitation and under Our authority. We knew that by comparing ideas and sharing the wisdom which each of you has derived from experience, you will be perfectly able to ensure that the unity of Church discipline is preserved among your peoples who are united by racial affinity; that morals worthy of the profession of the Catholic faith flourish; and that thus, by the concerted efforts of good citizens, the Church publicly prospers.
