Over the times, the thrust concerns of integral humanism have been driven within and along the values of the human family. For so many ecclesiological thinkers and theologians like John Paul II and Benedict XVI, the sustainability of the universe depends on the values place on the human family. Such social philosophy recognised that the human family is a common home for common and authentic development. It is a platform that places humanity as an end, not a means for the content of progress and advancement. After-all, humanity is conceived as the measure of all things. Humanity determines what should be called development. With such social and developmental conviction, humanities are expected to take more seriously the respects, promotion and protection of their families as the cradle of civilization and as a community of peace. Here, the paper philosophically revisits Benedict XVI’s 2008 Message for the World Day of Peace, by assessing its ethics of living for the realization of integral human development. Only through the valuation of the family can true peace, since the foundation of the human family is in God. The paper is also concerned about the trends of human civilization and development that should commonly adopted, along the dictates of natural law, in order to safeguard the human family from the effects of misguided and erotic world policies and programmes, that may even lead it into extinction in possible future, if human freedom and powers of legislations and innovations are not properly checkmated.
