11. In view of the risks which humanity is facing in our time, all Catholics in every part of the world have a duty to proclaim and embody ever more fully the ''Gospel of Peace'', and to show that acknowledgment of the full truth of God is the first, indispensable condition for consolidating the truth of peace. God is Love which saves, a loving Father who wants to see his children look upon one another as brothers and sisters, working responsibly to place their various talents at the service of the common good of the human family. God is the unfailing source of the hope which gives meaning to personal and community life. God, and God alone, brings to fulfilment every work of good and of peace. History has amply demonstrated that declaring war on God in order to eradicate him from human hearts only leads a fearful and impoverished humanity toward decisions which are ultimately futile. This realization must impel believers in Christ to become convincing witnesses of the God who is inseparably truth and love, placing themselves at the service of peace in broad cooperation with other Christians, the followers of other religions and with all men and women of good will.
[Pope Benedict, Message for the XXXIX World Day of Peace, 2006]
