Peace is based on respect for the rights of all. Conscious of this, the Church champions the fundamental rights of each person. In particular, she promotes and defends respect for life and the religious freedom of everyone.
Pope Benedict XVI, World Day of Peace Message, 2007
In today’s world, a world of unprecedented advances in many fields and yet one marked by crushing poverty, intractable conflicts, bloody violence and widespread denial of human rights, building an international order on the foundation of fundamental human rights is not simply a moral ideal; it is a practical necessity… Today’s advances in human knowledge and capacity offer humanity an unparalleled opportunity to affirm in law and practice the human dignity of every person, regardless of their religious tradition, social status, ethnic background, racial group, or national origin. But to move toward greater respect for human rights, humanity’s technological and economic achievements must be matched by moral advancement, greater commitment to human rights and the active pursuit of the universal common good of peace with justice. In the words of our late Holy Father, a genuine respect for human rights throughout the world would represent “a true milestone on the path of humanity’s moral progress.”
The principle of solidarity, also articulated in terms of "friendship" or "social charity," is a direct demand of human and Christian brotherhood…Solidarity is manifested in the first place by the distribution of goods and remuneration for work. It also presupposes the effort for a more just social order where tensions are better able to be reduced and conflicts more readily settled by negotiation. Socio-economic problems can be resolved only with the help of all the forms of solidarity: solidarity of the poor among themselves, between rich and poor, of workers among themselves, between employers and employees in a business, solidarity among nations and peoples. International solidarity is a requirement of the moral order; world peace depends in part upon this. The virtue of solidarity goes beyond material goods. In spreading the spiritual goods of the faith, the Church has promoted, and often opened new paths for, the development of temporal goods as well. Catechism of the Catholic Church, 1939-1942
