This document discusses integral human development from Catholic social teaching. It outlines Pope Paul VI's vision of development as advancing humanity from less human to more human conditions through meeting material needs, overcoming social issues, and growing in knowledge, dignity, and spiritual values like faith. Pope Benedict XVI's encyclical Caritas in Veritate elevates Populorum Progressio as providing a framework for development and integral humanism. True development requires respecting human freedom and responsibility as well as truth, and sees development as a vocation toward the good of all people and their fulfillment in God.
